SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance,

or use can cause fire, electrical shock, or other conditions which

may cause personal injury or property damage. Consult a qualified

installer, service agency or your distributor or branch for informa-

tion or assistance. The qualified installer or agency must use

factory-authorized kits or accessories when modifying this prod-

uct. Refer to the individual instructions packaged with the kits or

accessories when installing.

Follow all safety codes and wear safety glasses. Have fire

extinguisher available. Read these instructions thoroughly and

follow all warnings or cautions attached to the unit. Consult local

and state building codes and Sheet Metal and Air Conditioning

National Association (SMACNA) for special installation require-

ments.

Recognize safety information. This is the safety-alert symbol .

When you see this symbol on the unit or in instructions and

manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAU-

TION. These words are used with the safety-alert symbol. DAN-

GER identifies the most serious hazards which will result in severe

personal injury or death. WARNING signifies hazards which

could result in personal injury or death. CAUTION is used to

identify unsafe practices which would result in minor personal

injury or product and property damage.

INSTALLATION CONSIDERATIONS

Before the actual installation of a zoning system can begin,

decisions need to be made to determine the number and location of

zones and sensors. This affects duct and damper selections. For

assistance with these decisions, consult the Design Guide available

from your distributor or branch.

This instruction covers the physical installation and start up of the

Zone Perfect Plus system. Use this instruction to guide the actual

installation process after all the air side decisions have been made.

1. Install User Interface and Remote Sensors in non-

condensing areas with ambients between 32°F and 120°F.

Install Dampers and Equipment Controller in non-

condensing areas with ambients between 32°F and 158°F.

2. Dampers may need to be vibration isolated to reduce noise.

3. TXV is required in air conditioning and heat pump appli-

cations.

4. Use separate isolated transformer to supply power to Zone

Perfect Plus System (40 va minimum, class 2, field sup-

plied).

5. Proper equipment and duct sizing are important in a zoned

system. Be sure to refer to the Design Guide for assistance

in making these selections.

CAUTION: TXV on indoor coil is required on all

zoning installations.

INTRODUCTION

The Zone Perfect Plus System allows air conditioning and heating

equipment to control temperatures and humidity in up to 8 distinct

spaces or Zones within a building. Each zone has independent

temperature settings.

The comfort temperature settings can change automatically

through the use of schedules. This allows Zone Perfect Plus to

change temperature settings in zones to reflect occupancy or usage.

For example, you can condition the bedrooms in a home from 5:00

PM through 7:00 AM or the kitchen from 3:00 PM through 6:00

PM. The Zone Perfect Plus System uses motorized air volume

control dampers (also called zone dampers) to regulate flow of

conditioned air into zones. In this manner Zone Perfect Plus can

selectively heat or cool certain portions of a building depending

upon space temperature requirements.

Each zone requires a motorized zone damper to control the air

supplied to it and a zone sensor to sense zone temperature. There

are 3 types of zone sensors available and they may be used in

combination:

• User Interface — Each installation has only 1 User Interface.

This is the command center for the entire system, and it will

typically be located in Zone 1 to sense and control the

installation instructions

temperature in this zone. If desired, a Remote Sensor may be

used to sense the Zone 1 temperature. This can give the

installer some flexibility in locating the User Interface to

another area.

• Remote Sensor — This is a temperature sensor only, having no

additional user inputs.

• Smart Sensor — Any zone other than Zone 1 may use a Smart

Sensor. It provides a display of zone temperature and means to

adjust the desired temperature in that zone only. It also displays

the outdoor temperature and indoor humidity.

Be sure to select the desired sensor type for each zone. Standard

kits include only Remote Sensors. Other types must be purchased

separately. Installation Instructions for Smart Sensors are included

with them.

INSTALLATION

I. CHECK EQUIPMENT AND JOB SITE

A. Inspect Equipment

File claim with shipping company, prior to installation, if shipment

is damaged or incomplete.

II. COMPONENT LOCATION AND WIRING

CONSIDERATIONS

WARNING: To prevent personal injury or possible

equipment damage disconnect power supply before rout-

ing wire.

All wiring must comply with national, local, and state codes.

A. Locating Equipment Controller

All wiring is run back to the Zone Perfect Plus Equipment

Controller. Select a location near the furnace or fan coil where

wiring from the User Interface, each Remote Sensor or Smart

Sensor, each damper actuator, and the equipment itself can come

together easily.

The Zone Perfect Plus System is approved for indoor use only and

should never be installed with any of its components exposed to

the elements. The Equipment Controller (and the zone dampers)

may be installed in any area where the temperature remains

between 32° and 158°F, and there is no condensation. The cover

must be installed to prevent damage from other sources. Do not

locate where it will be accessible to children. Avoid areas in which

the sound of relays energizing on the Equipment Controller may be

an annoyance. It may be mounted in either vertical or horizontal

position. Remember that wiring access is likely the most important

consideration.

CAUTION: To prevent possible damage to Equipment

Controller, do not mount on plenum, duct work, or flush

against furnace.

B. Locating User Interface

The User Interface is the command center for the Zone Perfect

Plus system. It should be located where it is easily accessible and

visible to home or business owner. It is also normally the Zone 1

sensor and as such needs to be located to properly measure the

temperature in Zone 1. If these 2 requirements conflict, a separate

Remote Sensor can be added for Zone 1. When Remote Sensor is

connected to Zone 1 terminals (OS1 and OS1C) of Equipment

Controller, the system automatically switches to using this sensor

for Zone 1 and ignores the sensor within the User Interface. This

arrangement allows User Interface to be located at any convenient

place within the home or business, and only the Zone 1 Remote

Sensor must be located in Zone 1.

NOTE: The User Interface also controls humidity functions. If

the User Interface is not used to control Zone 1 temperature, it

must still be located in a suitable area where humidity control will

not be affected.

C. Locating Sensors

For proper operation, each sensor must accurately measure the

temperature within its zone. Remember that zone sensors can be a

combination of 3 different types as described in introduction.

For accurate temperature measurement, the following guidelines

should be followed:

Sensor should be mounted:

• Approximately 5 ft (1.5m) from floor.

• Close to the center of its zone, preferably on an inside wall.

• On a section of wall without pipes or duct work.

Sensor should NOT be mounted:

• Close to a window, on an outside wall, or next to a door leading

to the outside.

• Where it will be exposed to direct light and heat from a lamp,

sun, fireplace, or other temperature-radiating object which may

cause a false reading.

• Close to or in direct airflow from supply registers and return-air

grilles.

• In areas with poor air circulation, such as behind a door or in

an alcove.

The Remote Sensor terminals are not marked for polarity because

polarity is not important.

D. Wiring Considerations

All wiring in the Zone Perfect Plus system may be unshielded.

Ordinary thermostat wire is ideal. Use 22 gage or larger for normal

wiring. Lengths over 100 ft should use 20 gage or larger wire.

Remote Sensors require only 2 conductors, but it is recommended

that at least 4 conductors be run. This will allow a Smart Sensor to

replace the Remote Sensor with no wiring changes at a later date.

The User Interface requires 4 conductors, each damper actuator

requires 3 conductors. The connection to equipment (furnace or

fan coil) could require as many as 8 conductors for a multi-stage

installation. The leaving air temperature (LAT), heat pump tem-

perature (HPT)—used with heat pumps only, and optional outdoor

air temperature (OAT) sensors require 2 conductors each. The

outdoor air temperature sensor may be able to be connected at the

outdoor unit using existing wiring. Refer to Installation Instruc-

tions included with the outdoor air temperature sensor.

Cables with excess conductors are acceptable. Cut off or fold back

and tape any unneeded conductors.

Plan the routing of wiring early to avoid possible problems later

on.

Remember all wires converge at the Equipment Controller, so its

location is important.

III. INSTALL COMPONENTS

A. Install Equipment Controller

The Equipment Controller is designed so that wires can enter it

from behind, above, or below. Plan wire routing before mounting

Controller.

1. Open doors or remove cover to access mounting holes.

Remove the 2 Zone system cover from the left side first.

2. Mount back plate to wall using screws and wall anchors

provided.

3. Level back plate and tighten screws.

B. Install User Interface

1. Open User Interface rear door (mounting base) to expose

mounting holes. Press back half of the right end inward and

then pull front and back halves apart at the right end to

open. The mounting base (the back half of the plastic) can

be separated from the User Interface body by snapping the

hinge apart.

—2—

→

a. Remove hinged cover by snapping apart its hinge.

b. Separate the main body from the mounting plate by

snapping its hinge apart.

c. Mount base before wiring and attaching remaining parts.

2. Route User Interface wires through large hole in mounting

base. Level mounting base against wall and mark wall

through 2 mounting holes. Any thermostat cable of 4 or

more conductors may be used. Shielded cable is not needed.

3. Drill two 3/16-in. holes in wall where marked.

4. Secure mounting base to wall with 2 screws and anchors

provided, making sure all wires extend through hole in

mounting base.

5. Adjust length and routing of each wire to reach proper

terminal and connector block on mounting base with 1/4 in.

of extra wire. Strip only 1/4 in. of insulation from each wire

to prevent adjacent wires from shorting together when

connected.

6. Match and connect 4 wires to proper terminals of the

connector blocks. Recommended connection is RED to V+,

WHITE to VG, BLUE or YELLOW to RS+, and GREEN

to RS-.

CAUTION: Improper wiring or installation may damage

the User Interface. Check to make sure wiring is correct

before proceeding with installation or turning on unit.

7. Push any excess wire into wall and against mounting base.

Seal hole in wall to prevent air leaks. Leaks can affect

operation.

8. Snap hinge back together.

9. Close User Interface assembly making sure pins on back of

circuit board align with sockets in connector.

C. Install Remote Sensors

1. Separate the sensor and mounting back plate (with provided

screws and anchors). Squeeze the top and bottom of the

cover together firmly by grasping the raised top and bottom

ridges. This will release the cover.

2. Pull a 2-conductor wire through hole on right-hand side.

3. Recommended connection is BLACK to either terminal,

WHITE to remaining terminal. Stranded or common bell

wire may be used. Lengths up to 1000 ft will contribute no

noticeable error.

4. Align sensor case with base plate then press firmly until

cover snaps into place.

For installation of other sensor types, refer to Installation Instruc-

tions provided for them.

IV. INSTALL ZONE DAMPERS

Proper selection and sizing of dampers is very important for proper

system operation. Be sure to consult the System Design Manual for

assistance in making these selections. Selection and sizing infor-

mation is not provided in this installation instruction.

If conditions exist for possible condensation, do not mount the

actuator beneath the duct.

If duct work requires multiple dampers for a single zone, up to 3

dampers may be wired in parallel. A multi-damper enabler is not

needed.

For retrofit applications, older type dampers with their original

actuators may be used under the following conditions:

1. A single damper may be connected directly to a Zone

Perfect Plus output.

2. If multiple dampers are needed for a single zone, a

multi-damper enabler must be used.

Older type dampers having an extended shaft and driven by a

crank arm may be fitted with the new DAMPACT actuators for

quieter operation. Mounting is straightforward. Be sure to use 45°

actuators (part No. DAMPACT45DEG) with round dampers and

90° actuators (part No. DAMPACT90DEG) with rectangular

dampers. When new actuators are fitted to older dampers, multi

damper enablers are not needed and up to 3 actuators can be

connected in parallel to a single Zone Perfect Plus output.

Zone dampers may be installed in any position.

Install dampers so that actuator is visible for inspection and

accessible in the event it would ever need to be serviced. The black

mark on the end of damper shaft represents position of damper

blade.

NOTE: Insulate damper using 1-1/2 in. insulation (check local

codes). In areas where excessive condensing may occur, carefully

insulate over the actuator assembly. Make sure insulation does not

interfere with operation of actuator.

Before insulating over the actuator, check for proper damper

operation. This will be done as part of the installer set up or may

be done by applying 24vac between COM and OPN to open

damper and between COM and CLS to close damper. (See Fig. 1.)

The damper will modulate counter-clockwise to open and clock-

wise to close (viewed from the actuator end).

If in an emergency it becomes necessary to force a damper open,

manually press in the red quick blade release button with one hand

and turn mounting hub to reposition damper shaft. Release button

to hold damper shaft in new position.

A. Round Metal Duct Work

1. Crimp end of branch duct.

2. Slip end of zone damper over end of duct work. Use

self-tapping sheet metal screw to secure. (See Fig. 2.)

3. Properly seal joint using duct tape, mastic, or other ap-

proved method. Do not allow mastic to come in contact

with actuator.

4. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check

your local codes.)

NOTE: All zone dampers and duct work must be properly

supported according to local codes or SMACNA standards.

with actuator.

3. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check

your local codes.) (See Fig. 4.)

NOTE: All zone dampers and duct work must be properly

supported according to local codes or SMACNA standards.

C. Round Flexible Duct Work

1. Slip 1 end of flexible duct work over 1 end of zone damper.

(See Fig. 5.)

2. Secure flexible duct to zone damper using SMACNA or

other approved method.

3. Properly seal joint using duct tape, mastic, or other ap-

proved method. Do not allow mastic to come in contact

with actuator.

4. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check

your local codes.) (See Fig. 6.)

NOTE: All zone dampers and duct work must be properly

supported according to local codes or SMACNA standards.

D. Rectangular Fibrous Glass Duct Work

1. Insert 1 end of zone damper into 1 end of fibrous glass duct

work approximately 2 to 3 in. (See Fig. 7.)

2. Screw field-supplied screws and tabs into zone damper.

3. Properly seal joint using duct tape, mastic, or other ap-

proved method. Do not allow mastic to come in contact

with actuator.

4. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check

your local codes.) (See Fig. 8.)

V. INSTALL BAROMETRIC BYPASS DAMPER

NOTE: The barometric bypass damper is a critical part of Zone

Perfect Plus System for controlling noise at minimum airflow. A

barometric bypass should be installed unless the duct work and

indoor unit have been sized for use without a bypass.

The bypass should be installed according to local codes and

SMACNA standards. Be sure bypass is properly supported.

For proper installation, refer to Installation Instructions packaged

with barometric bypass.

CAUTION: Failure to properly install leaving air tem-

perature sensor can cause permanent damage to the

HVAC equipment.

VI. INSTALL LEAVING AIR TEMPERATURE (LAT)

SENSOR

Locate LAT sensor in main supply trunk after heating and cooling

coil and before bypass damper and first branch. The LAT sensor is

radiant shielded to prevent heat from affecting correct air tempera-

ture.

1. Drill a 1/4-in. hole at location in supply trunk where sensor

will be installed.

2. Insert sensor in hole and use as a template to mark the 2

mounting holes.

3. Drill two 1/16-in. holes to accept No. 6 screws through

pre-drilled holes in duct temperature sensor back plate.

4. Use 2 No. 6 sheet metal screws to mount duct temperature

sensor to unit.

5. Connect sensor to 2-conductor wire using provided wire

nuts. (See Fig. 9, 10, or 11 for connection to Equipment

Controller.)

VII. INSTALL HEAT PUMP TEMPERATURE (HPT)

SENSOR

The HPT sensor is required in all heat pump/fan coil installations.

It is not used in dual fuel(heat pump/furnace installation). It

measures the temperature of the air leaving the indoor coil. The

sensor is to be installed downstream of the indoor coil but before

the electric heaters. It can be installed through the wall of the fan

coil or may be located entirely inside the fan coil near the blower

inlet. Anchor firmly in place with cable ties so that it cannot

interfere with the blower wheel. (See Fig. 9, 10, or 11 for

connection to Equipment Controller.)

VIII. FINAL WIRING

Bring all Equipment Controller wires together at Equipment

Controller. Make all connections as indicated on Fig. 9 (for 2-zone

installations), Fig. 10 (for up to 4-zone installations), or Fig. 11

(for up to 8-zone installations).

Figures 15 through 38 show the connection between the Equip-

ment Controller and the HVAC equipment. Select proper diagram

for your equipment and connect accordingly. This connection will

require as few as 4 or as many as 7 conductors. See Table 4 to

identify the correct wiring figure.

NOTE: Table 4 and wiring diagrams appear in sequence near the

end of this document.

NOTE: It is good practice to mark each wire as the final

connection is made. This will preserve its identity if it is ever

disconnected.

Separable RC and RH connections are provided for systems with

separate transformers for heating and cooling. To accommodate

separate transformers, cut jumper R12 on the Equipment Control-

ler board. It is located just below and to the right of the RC and RH

connections. As shipped, the R12 jumper ties RC and RH

terminals together so either can be used in single transformer

application.

When installing a 24-vac humidifer, connect it directly to the

HUM terminal on Equipment Controller, and C terminal of indoor

equipment. Do not use an external humidstat. All necessary control

is provided by Zone Perfect Plus.

When using an FK series fan coil, connect DHUM (dehumidify)

output directly to DH terminal of fan coil. This output may also

drive a relay (connected with other side to C) which can be

connected to reduce fan speed in other types of blowers. The relay

will be energized when humidity is normal and will deenergize

when humidity is high, calling for reduced fan speed.

An LAT sensor must be connected in all systems. Both LAT and

HPT sensors must be connected in heat pump/fan coil systems.

WIRING CONSIDERATIONS

Zone Perfect Plus treats all furnaces as if they were 2-stage. For

single stage equipment, connect to W1. The same holds true for

auxiliary heat in fan coils. (Refer to Fig. 15-38.)

With any 2-stage furnace, configure the furnace so that low fire is

controlled by W1 and high fire is controlled by W1 and W2

together. This means the internal algorithm is to be disabled. See

furnace instructions.

Some variable speed furnaces have a "zoning" setting. If such a

setting exists, it should be turned on. It forces the furnace to adjust

its airflow more frequently to accommodate the effects of damper

movement. See furnace instructions.

All 2-speed air conditioners and heat pumps need to be configured

so that Y1 controls low speed and Y1 and Y2 together control high

speed in both heating and cooling. This is usually done by

selecting the "zoning" position of the stage 2 latch pot. See 2-speed

equipment instructions.

In 2-speed dual fuel applications (2-speed heat pump and furnace),

do not set the furnace interface jumper on the heat pump to ON,

even though its instructions say to do so. The necessary interlock-

ing to keep both the heat pump and furnace from operating at the

same time is done by Zone Perfect Plus.

The special 3-stage auxiliary heat feature of Bryant thermostats is

incorporated into Zone Perfect Plus. This requires an FK type fan

coil and specific heater packages with a single-speed heat pump.

See FK fan coil Installation Instructions.

IX. UNDERSTANDING SEQUENCE OF OPERATION

A. Temperature Set Points

The Zone Perfect Plus System uses 2 temperature set points for

each zone, the higher for cooling and the lower for heating. A

minimum difference of 2°F is enforced between the 2 set points.

Each set point may be manually adjusted or controlled by a

programmed time schedule established by the home or business

owner.

B. Heating and Cooling Comfort Set Points

If space temperature is between heating and cooling set points for

the zone, then the zone is said to be "satisfied" with respect to

temperatures. When a zone is satisfied, no heating or cooling is

required. When all zones are satisfied, there is no demand and the

equipment is turned off. For example, if cooling set point is 76°F

and heating set point is 72°F, then a space temperature of 73°F is

assumed to be satisfactory and no heating or cooling of the zone is

required.

If space temperature in a zone falls below heating set point, then

that zone needs to have heat added to zone which will raise space

temperature back to heating set point. For example, if heating set

point is 72°F and space temperature is 70°F, then space tempera-

ture must be raised 2°F in order for zone to be satisfied. In this

case, temperature "heating demand" for zone is 2°F. (72° minus

70°F.)

Otherwise, if space temperature in a zone rises above cooling set

point, then that zone needs to have heat removed from zone which

will lower space temperature back to cooling set point. For

example, if cooling set point is 76°F and space temperature is

77°F, space temperature must be lowered 1°F in order for zone to

be satisfied. In this case, "cooling demand" for zone is 1°F. (77°

minus 76°F.)

C. Out Feature

A new feature called OUT can be selected via the OUT button.

When this selection is made, the system is being told that the

selected zone is unoccupied. It will normally supply no condition-

ing to an OUT zone. If zone temperature exceeds 85°F or goes

below 60°F, conditioning will be supplied to maintain the zone

within these limits.

The system will also use OUT zones to relieve the equipment

under overload conditions. If the total demand from all zones is

such that airflow is insufficient (or bypassing is excessive) this

condition will be sensed by the LAT or HPT temperature sensors.

When these temperatures begin to approach their limits, Zone

Perfect Plus will first begin to open dampers in the OUT zones to

relieve overload condition. The system will also monitor tempera-

tures in the OUT zone and never allow them to become cooler than

the coolest zone (in cooling) or warmer than the warmest zone (in

heating). This prevents over conditioning of OUT zones while still

using them to relieve an overload condition.

Zones can be set to OUT at any time or OUT can be programmed

like any other temperature. The home or business owner can then

program OUT for times that the zone is not likely to be occupied.

When OUT is selected, both heating and cooling set points are

replaced by "--."

D. Sequence Of Events For Normal Heating Or Cooling

Cycle

Given comfort set points and space temperature for zones within

system, Zone Perfect Plus will determine if active heating or

cooling is required. If so, Zone Perfect Plus will perform the

following:

1. Fully open 1 or more dampers and position others so that all

zones will be conditioned back to their set points at the

same time.

2. Turn on equipment.

3. While equipment is on, continually make small adjustments

in damper positions so that all zones converge on their set

points at the same time.

4. Turn off equipment when all zones reach their set points.

5. Leave dampers at their final positions while equipment is

off.

6. If equipment does not run for 2 hours, it will fully open all

dampers.

This is the basic sequence of operation for the Zone Perfect Plus

system. The actual control of dampers, HVAC equipment, and

system fan will change with the configuration of system. Depend-

ing upon configuration, Zone Perfect Plus can control heat pumps,

furnaces, and dual fuel applications.

E. Control Strategy for Heating / Cooling Stages

The Zone Perfect Plus system will attempt to minimize use of

additional stages of heating or cooling equipment.

Zone Perfect Plus controls multi-stage equipment in response to

the level of demand and the number of zones with demand. In

general, it tries to satisfy demand with a minimum number of

stages. In heat pump systems, where auxiliary heat is usually

expensive, a small extra demand is required to bring on auxiliary

heat. This acts to prevent the unnecessary use of auxiliary heat. In

addition, when an outdoor sensor is attached, the system can be set

to lock out auxiliary heat for outdoor temperatures above an

installer selectable value. This will be covered under System

Configuration.

SYSTEM CONFIGURATION

Zone Perfect Plus must be configured to match the type of

equipment connected to it. In addition, there are several choices of

configuration based on how the user wants the system to operate.

Configuration is done in 2 parts. One is the setting of 8 DIP

switches on the Equipment Controller. The second is a group of 11

software selections made via User Interface. Follow the sequence

below for easy setup.

Configuration of the Equipment Controller is done first with the

power off. Then power is applied and the User Interface is

configured with power on.

NOTE: A DIP switch module is oriented with switch 1 at the

bottom and switch 8 at the top. Refer to Fig. 12 for switch

orientation and labels.

I. EQUIPMENT CONTROLLER CONFIGURATION

Located near bottom of Equipment Controller circuit board, there

is an 8 section DIP switch. The use of each switch is described

below. Using a pen or pencil, set each switch to its proper state.

ON is to the left and is the factory setting. OFF is to the right. Fig.

12 is a pictorial drawing of this selector switch.

Switch 1—Selects AC or HP.

ON—Selects AC.

OFF—Selects HP.

Switch 2—Selects single- or 2-speed compressor.

ON—Selects single speed.

OFF—Selects 2 speed.

Switch 3—Selects 3-stage electric heat. Equipment must include

FK fan coil with single-speed heat pump and selected heater with

2:1 ratio element size.

ON—Normal 1- or 2-stage electric heat.

OFF—Special 3-stage electric heat.

Switch 4—Selects Smart Recovery in both heating and cooling.

The system starts adjusting temperature 1-1/2-hours earlier than

selected recovery time so it will arrive at new temperature at

selected time.

ON—Smart recovery.

OFF—Normal recovery.

Switch 5—Zone system address selection. When 2 zoning systems

are connected together, the second system should be set to OFF.

ON—Normal single system.

OFF—Address selection for second zoning system.

Switch 6—Select installer test mode to assist in checking out the

system. See Starting System.

ON—Selects normal operation.

OFF—Selects installer test mode.

Switch 7—Disables cooling when outdoor temperature is below

55°F. Requires outdoor air temperature sensor.

ON—Cooling enabled at all temperatures.

OFF—Low temperature cooling disabled.

Switch 8—Dual fuel selection for systems with heat pump and

furnace.

ON—Selects normal system.

OFF—Selects dual fuel system.

II. USER INTERFACE CONFIGURATION

The User Interface is configured via a group of selections made

through the keypad in a special configuration mode. Before the

equipment is operated, the system must be properly configured.

Make sure this step is not left out.

Before turning power on to the zoning system, disable the system

equipment itself by either turning off its main power or by

temporarily disconnecting its 24-vac power at the RC and RH

terminals of the Equipment Controller. This will allow the zoning

system only to operate. Go through the following steps with the

equipment power off.

By this time 8 DIP switches on the Equipment Controller should

be properly set.

Turn on power to the zoning system by applying power to its

24-vac transformer. When power is first applied to Zone Perfect

Plus the Equipment Controller immediately begins positioning all

dampers to fully open by running each damper motor in the open

direction for 15 sec. This is done in succession, 2 zones at a time,

starting with Zone 1. The time required will be 15 sec for each pair

of zones. Remember that the system automatically determines the

number of zones by detecting the presence of zone sensors.

—8—

→

At power up the User Interface displays all segments for a few sec.

This is followed by the selected system type for an additional few

sec. The system type shows as follows:

1. AC—1-Speed Air Conditioner

2. HP—1-Speed Heat Pump

3. A2—2-Speed Air Conditioner

4. H2—2-Speed Heat Pump

5. AS—1 or 2-Speed Air Conditioner with 3-Stage Auxiliary

Heat

6. HS—1 or 2-Speed Heat Pump with 3-Stage Auxiliary Heat

7. dF—Dual Fuel with 1-Speed Heat Pump

8. d2—Dual Fuel with 2-Speed Heat Pump

Power-on check of the User Interface itself can be done by

separating the User Interface from its backplate and then recon-

necting it by attaching the 2 parts. This will allow observation of

the User Interface at power up.

Several installer select options are set using the User Interface

keypad.

These configuration options, like DIP switch settings, are intended

to be selected at installation and are normally not modified by

home or business owner. These options are not discussed in the

Owner’s Guide and therefore must be made as part of the

installation. A special procedure allows entry into configuration

mode. Zone Perfect Plus will automatically exit this mode if no

button is pressed for 3 minutes. While in the configuration mode,

11 configuration choices can be made. In addition, LAT and HPT

temperatures as well as all damper positions can be viewed. A brief

description of each is given below, followed by instructions on

how to make the selection.

A. To Enter the Configuration Mode:

Press and hold FAN button for approximately 10 sec until room

temperature and set point displays change to 2 numbers. You are

now in the configuration mode.

Option 1—Clean filter timer

Option 2—English/Metric

Option 3—Fan ON with W

Option 4—User Interface address

Option 5—Disable zoning

Option 6—Ignore LAT and HPT safeties

Option 7—Variable speed blower present

Option 8—Select LAT shutdown temperature

Option 9—Auxiliary heat lockout

Option 10—Dual fuel crossover temperature

Option 11—Auto changeover timer

Option 12 to 18—Not available

Option 19—Display HPT temperature reading

Option 20—Display LAT temperature reading

Option 21 and up—Display zone damper positions.

NOTE: If END button is pressed or if no button is pressed for 180

sec, Zone Perfect Plus will exit configuration mode and return to

normal operation. To re-enter configuration mode, FAN button

must be pressed and held for 10 sec again.

While in configuration mode, the large display shows the selection

which has been made and the smaller display (COOL set point

display) shows current option number. One of these will be

flashing.

The up and down buttons are used both to move between available

options and to make selection for each option. When option

number (small display) is flashing, the up and down buttons adjust

it, moving between available option numbers. After desired option

number has been selected, press SET TIME/TEMP button. The

large display will now flash, indicating that the up and down

buttons now control available choices within that option. Each

press of the SET TIME/TEMP button switches between available

option (small display) and available selections within each option

(large display).

Available options and available selections for each are described

below.

OPTION 1—CLEAN FILTER TIMER

Select hours of blower operation (heating, cooling, or fan) before

CLEAN FILTER icon is displayed. With OFF selected, icon will

never come on, disabling this feature. Time selection can be from

400 to 3600 hours by selecting numbers 1 through 9. (Time is

400X number selected.) Factory default is 2 (800 hours). Recom-

mended selections are: disposable filter—400 to 800 hours, media

filter—1200 to 1600 hours, or electronic air cleaner—1600 to 2400

hours of blower operation.

OPTION 5—DISABLE ZONING

When this option is selected, all dampers go fully open and zone

1 sensor (normally User Interface itself) becomes the sensor for the

entire home or business. In effect, the zoning system disappears

and is replaced by a single thermostat. In this mode, the ZONE X

where X is the zone number is not displayed. Factory default is OF

(off), zoning enabled. This option is used to check out the system

equipment. The User Interface acts as normal thermostat.

TO SELECT:

1. Enter configuration mode (if not already there).

2. Use up and down buttons to display 5 on flashing small

display.

3. Press SET TIME/TEMP button once to flash large display.

4. Use up and down buttons to alternate between ON and OF

(off). Remember: OF (off) enables zoning, ON disables

zoning.

5. Press SET TIME/TEMP button again to flash 5 on small

display, or press END button to exit configuration mode.

OPTION 6—IGNORE LAT AND HPT TEMPERATURES

CAUTION: Leaving this selection ON can cause perma-

nent damage to HVAC equipment

This option, when ON, tells the system to ignore the LAT and HPT

temperature information. It should only be used for troubleshoot-

ing and to allow temporary operation with a failed or missing

sensor until the sensor can be replaced. Factory default is OF (off).

TO SELECT:

1. Enter configuration mode (if not already there).

2. Use up and down buttons to display 6 on flashing small

display.

3. Press SET TIME/TEMP button once to flash large display.

4. Use up and down buttons to alternate between ON and OF

(off). Remember ON is for temporary use only.

5. Press SET TIME/TEMP button again to flash 6 on small

display, or press END button to exit configuration mode.

OPTION 7—VARIABLE SPEED (ICM) OR PSC BLOWER

If the furnace or fan coil contains a variable speed ICM blower, set

this option ON. For normal (PSC) blowers, set to OF (off). This

selection enables the system to use the special dehumidification

features available only with the ICM blower. Factory default is OF

(off).

TO SELECT:

1. Enter configuration mode (if not already there).

2. Use up and down buttons to display 7 on flashing small

display.

3. Press SET TIME/TEMP button once to flash large display.

4. Use up and down buttons to alternate between OF (off) and

ON.

5. Press SET TIME/TEMP button again to flash 7 on small

display, or press END to exit configuration mode.

OPTION 8—LEAVING AIR TEMPERATURE (LAT) SHUT-

DOWN TEMPERATURE

This option selects maximum allowable LAT in furnace and fan

coil auxiliary heat installations. Equipment will be turned off if its

LAT exceeds selected value. Values are 35, 40, 45, 50, 55, 60, 65,

70, or 75 corresponding to temperatures of 135° to 175°F. As LAT

nears selected limit, actions are taken by the system to try to reduce

the LAT. These include staging down multi-stage equipment and

limited conditioning of OUT zones.

When the LAT temperature approaches its limit, OUT zone

dampers progressively open, allowing more airflow into the duct

system. The temperatures of the OUT zones are also monitored. As

any OUT zone approaches the temperature of the most conditioned

zone, its damper closes again, preventing the OUT zone from

being over conditioned. If OUT zones are not available and LAT

temperature cannot be maintained at a safe value, the system will

shut down the equipment when the LAT temperature reaches its

limit. With earlier Comfort Zone systems, temperature set here

was temperature where actions were started. Shutdown tempera-

ture was 20°F higher than selected temperature. Therefore a setting

of 155°F on Zone Perfect is equivalent to 175°F on Zone Perfect

Plus.

HPT temperature limit for shut down is fixed at 115°F and cooling

LAT temperature limit for shut down is fixed at 40°F (down from

Zone Perfect which was 45°F.)

Fan coils vary greatly in their LAT (leaving air temperature)

because of variations in the size of their heaters and their air flow.

This makes proper selection of LAT limits difficult. A value of 50

—10—

→

(150 °F limit) should be adequate. After the system is in operation,

LAT can be monitored via User Interface (configuration option 20)

to check actual operating temperature. For furnaces select a value

of 75°F plus the rated maximum temperature rise from the furnace

nameplate. Factory default is 50 (or 150°F).

TO SELECT:

1. Enter configuration mode (if not already there).

2. Use up and down buttons to display 8 on flashing small

display.

3. Press SET TIME/TEMP button once to flash large display.

4. Use up and down buttons to alternate between 35, 40, 45,

50, 55, 60, 65, 70, and 75.

5. Press SET TIME/TEMP button again to flash 8 on small

display, or press END button to exit configuration mode.

OPTION 9—AUXILIARY HEAT/DUAL FUEL UPPER LOCK-

OUT TEMPERATURE SELECTION

This option is available only with heat pump and dual fuel systems.

In heat pump systems, auxiliary heat is prevented from coming on

while outdoor temperature is above the selected value. In dual fuel

systems, the furnace is prevented from operating while outdoor

temperature is above the selected value. This temperature must be

set higher or equal to that of option 10. (See option 10 below.)

Outdoor temperatures of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, or

55°F, or OF (off) may be selected. If OF (off) is selected, outdoor

temperature does not affect system operation. Factory default is

OF (off).

TO SELECT:

1. Enter configuration mode (if not already there).

2. Use up and down buttons to display 9 on flashing small

display.

3. Press SET TIME/TEMP button once to flash large display.

4. Use up and down buttons to alternate between OF (off), 5,

10, 15, 20, 25, 30, 35, 40, 45, 50, or 55.

5. Press SET TIME/TEMP button again to flash 9 on small

display, or press END button to exit configuration mode.

OPTION 10—DUAL FUEL LOWER LOCKOUT

TEMPERATURE SELECTION

This option is only available with dual fuel systems. While outdoor

temperature is below the selected value, only the furnace is used

for heating. This option must be set higher than or equal to that of

option 9. (See option 9 above.) If the temperature selections of

option 9 and 10 are set to the same value, a dual fuel system will

use the heat pump only above this temperature and the furnace

only below this temperature. If the selections are different, the

range between the 2 selections will use the heat pump as the first

stage and the furnace as the second stage. Once the furnace comes

on, it will remain on until the demand is satisfied. The following

cycle will start with the heat pump. Outdoor temperatures of 5, 10,

15, 20, 25, 30, 35, 40, 45, 50, or 55°F, or OF (off) may be selected.

If OF (off) is selected, outdoor temperature does not affect system

operation. Factory default is OF (off).

other options or press END button to exit configuration

mode.

SYSTEM STARTUP AND CHECKOUT

Zone Perfect Plus is designed with built-in checkout capability for

both the equipment and the zoning system. Use the sequence

below for trouble free setup. When it is time to start up system for

the first time, you may want to check out the zoning system first

and the equipment second or to reverse the process, checking

equipment first and zoning system second. Either way is accept-

able.

The following sequence checks out zoning system first. If you

wish to check equipment first, proceed to Step 4 below. Then, after

equipment is operating properly, return to Steps 1, 2, and 3 to

check out zoning system.

I. ENABLE INSTALLER SETUP MODE

Before proceeding, temporarily disconnect all Y and W wires at

Equipment Controller so that heating and cooling cannot occur

during Steps 1 and 2. Leave G connected so that fan can operate.

Select installer setup mode at the Equipment Controller by moving

DIP switch No. 6 to the OFF position. (See Fig. 12.) This may be

done with power on or off. This mode is indicated by InSt

appearing in the User Interface clock display. In this mode

several special features are available to assist in the setup/checkout

process:

a. When a zone is selected with the NEXT ZONE button,

its damper opens fully and all other dampers close.

b. The selected zone’s temperature appears on the large

display.

—11—

→

c. The FAN button turns the blower ON or OFF.

d. The MODE button operates HEAT, COOL, or EHEAT

for 2 minutes and then returns automatically to OFF. No

demand from the zones is needed to bring on the

equipment in installer setup mode.

II. CHECK DAMPER AND SENSOR OPERATION

At the User Interface, set the mode to OFF using the MODE

Button to make sure cooling or heating outputs are not turned on.

Use the FAN button to turn on the blower by selecting ON (not

AUTO) under the fan icon. This will start the blower (if its supply

power is on). Use the NEXT ZONE button to select ZONE 1 above

the large display. This will open Zone 1 fully and close all other

zones. It will take the system 15 sec for each zone to complete this

process.

You may now observe the dampers to verify their positions are

correct (and check for air blowing out all Zone 1 registers only).

The large display reads the temperature in Zone 1. Use this

opportunity to verify the Zone 1 sensor is properly connected and

is located in Zone 1 by breathing on the Zone 1 sensor and

observing the temperature change. Remember, the Zone 1 sensor is

normally inside the User Interface but a remote sensor may be

used.

Use the NEXT ZONE button to select Zone 2 and repeat the above

process. Continue through all zones. When finished, you will have

verified that all the dampers and zone sensors are properly

connected and working.

III. QUICK CHECK OF EQUIPMENT OPERATION

Either this or the next step (Step 4) may be used for initial startup.

This check runs equipment for only 2 minutes on each stage and is

adequate to see that each stage comes on properly. For temperature

rise, charge levels, etc. use the longer check, or disable zoning

feature.

Be sure installer setup is still selected (Equipment Controller DIP

switch No. 6 is OFF).

Reconnect W and Y wires to enable equipment operation.

At User Interface, select HEAT mode. The first stage of heat will

come on immediately (no temperature demand is needed). For a

heat pump, this will be Y1 and G. For an air conditioning system,

this will be W1. The first stage will remain on for 2 minutes. Then

the second stage of heat will come on for 2 minutes. This will be

Y1, Y2, and G for a heat pump, or W1 and W2 for an air

conditioning system. At the end of 4 minutes, equipment will turn

off and mode will automatically return to OFF. If mode is set to

OFF at any time during 4 minutes, equipment will turn off

immediately. Note that single stage system (heat or cool) will

remain on for full 4 minutes because there will be no connection

to Y2 or W2.

The same applies to COOL. When selected, cooling will come on

immediately with no need for temperature demand. First stage will

be Y1, G (and O if a heat pump) and will run for 2 minutes. Then

Y1, Y2, G (and O if a heat pump) will come on for next 2 minutes.

At the end of 4 minutes equipment will turn off and mode will

return to OFF.

In a heat pump system, EHEAT may also be selected at User

Interface. This will turn on W1 only for first 2 minutes and then

W1 and W2 for the second 2 minutes. The compressor will not run.

As above, equipment may be turned off at any time during the 4

minutes by setting mode to OFF.

For all operation in this installer setup mode, no demand is needed,

no compressor timeguard exists, and no temperatures are moni-

tored. This means there is no protection for equipment, and this is

the reason that operation is limited to 4 minutes.

When leaving this step, be sure to return installer setup switch

(Equipment Controller DIP switch No. 6) to ON position. This will

enable normal operation.

When any output is turned on, a red LED on the Equipment

Controller board adjacent to the output’s connection terminal is

also turned on. This can be used at any time to monitor the state of

the Equipment Controller outputs, even if the equipment is not yet

connected or powered. Remember, the DEHUM output is a reverse

logic relay. This means its LED will be ON while there is no

dehumidify demand. See dehumidification section.

IV. LONGER CHECK OF EQUIPMENT OPERATION

When more detailed tests need to be made on equipment, the 2 or

4 minute run time provided in Step 3 may not be adequate. By

selecting disable zoning mode (turn Option No. 5 to ON under

User Interface configuration), system operates like a standard

thermostat system. All dampers go fully open, and the zone which

is displayed on User Interface provides set points. This zone’s

temperature is the only controlled temperature. Equipment will

operate as if it were being controlled by a single thermostat in the

displayed zone. Use this option to check out equipment as you

would with a normal thermostat. When finished, be sure to return

to the configuration mode and turn Option No. 5 OFF to enable

normal zoning operation.

FINAL INSTALLATION SETTINGS

→HUMIDIFICATION

If a humidifier is included in the system, Zone Perfect Plus can

directly control it. If a conventional humidity control exists, it

should be removed and the zoning system used in its place. Zone

Perfect Plus provides superior convenience and features. When

installing a 24-vac humidifier, connect it directly to the HUM

terminal on the Equipment Controller and C terminal of indoor

equipment.

A humidity sensor is built into the User Interface to monitor and

control relative humidity. The HUM output will control any

humidifier with a 24-vac input. A humidify set point can be set by

the home or business owner to any value between 10 percent and

45 percent or can be turned off. When the humidity drops 2 percent

below the set point, the HUM output is activated to turn on a

humidifier. When the humidity rises 2 percent above the set point,

the HUM output will turn off.

When an outdoor air temperature sensor is attached, an automatic

humidity level adjustment can be selected. This selection provides

a 1 percent reduction in the humidity set point for every 2 degrees

reduction in outdoor temperature. The set point can be changed at

any time, and it will then automatically adjust itself up and down

with changes in outdoor temperature. In no case will the set point

go above 45 percent or below 10 percent. This feature is to prevent

sweating of windows in very cold weather while allowing higher

humidity levels in warmer weather.

Another selection involves the interlocking of the HUM output to

heating or fan operation. The HUM output can be set to come on

only when there is a humidity demand and any heat output is on

(heat pump, furnace, or auxiliary heat). A second setting allows the

HUM output and the blower to turn on when there is humidity

demand. This selection allows humidification with the fan when

there is a no heat call. In no case will the HUM output be on

without either heat or fan.

It may be advisable to configure the humidity control as part of the

installation process. Following is a brief description of the hu-

midify setup process. It is also covered in the Owner’s Manual.

There are 5 selections for humidification in the heating mode:

1. Normal Humidify

2. Fan Humidify

3. Auto Humidify

4. Auto and Fan Humidify

5. OFF

—12—

→

To make a humidification selection or change the humidity (hu) set

point, a 2-button keypad press is required. Press SET TIME/TEMP

and FAN buttons simultaneously (indicated on the keypad by the

RH symbol) to enter the humidity mode. Either hu (humidify) or

dhu (dehumidify) will appear on the display. Use the SET

TIME/TEMP buttons to select hu (humidify). Now UP and

DOWN buttons may be used to adjust the value of the humidify set

point to a value between 10 and 45 percent. One of the following

humidification modes may also be selected:

1. Normal Humidify Mode — This is the factory default. This

configuration will bring on the humidifier only in the

heating mode when there is a humidify demand.

2. Fan Humidify Mode — This is selected by pressing FAN

button to turn on FAN icon. This configuration allows a

humidify demand to turn on the fan and humidifier together,

even if there is no heat demand.

3. Auto Humidify — This is selected by pressing MODE

button to turn on AUTO icon. This configuration allows the

rh set point to automatically track and adjust according to

the outdoor air temperature. The set point will automatically

increase or decrease with every 2°F change in outdoor

temperature between 0° to 50°F. To use this feature an

outdoor air sensor must be attached, or an E3 error will

occur.

4. Auto and Fan Humidify — This is selected by pressing both

MODE button and FAN button to turn on AUTO and FAN

icons. This configuration combines both fan humidify and

auto humidify together in bringing on the humidifier when

there is a humidify demand (without any heating demand),

and will automatically track and adjust the rh set point

according to the outdoor air temperature.

5. Humidify Off — This is used to disable the humidify mode.

To turn the humidify function OFF, use DOWN button to

scroll the humidity set point all the way down. The lowest

setting will be 10 percent before off (OF) appears in the

display. When OF is displayed, the humidification mode is

disabled.

To exit humidity setup mode, press END button, or if no buttons

are pressed for 3 minutes, the User Interface will save and exit this

mode returning to normal operation.

→DEHUMIDIFICATION

Zone Perfect Plus contains a rich set of capabilities for the

enhancement and control of dehumidification, particularly when

used with a variable speed (ICM) blower.

A dehumidification set point(separate from the humidification set

point) can be set to a value between 50 percent and 90 percent

humidity or can be turned off. When the humidity rises above this

set point by 2 percent, the dehumidify output is turned off. When

the humidity falls to 2 percent below this set point, the dehumidify

output turns on, supplying 24vac at its output. This output can be

used to control any 24-vac device which decreases humidity when

its control signal is removed.

When a variable speed blower with a dehumidify input is used

with the system, the dehumidify output can be connected to its

dehumidify input. This connection provides reduced cooling air

flow while dehumidification is needed yielding better moisture

removal from cooling air.

If the system has a 2-speed compressor (as selected by Equipment

Controller DIP switch No. 2) and a PSC blower (as selected by

User Interface Option No. 7), a dehumidify demand will make

compressor operate at high speed only for any cooling demand.

High speed provides better water removal than low speed when a

2-speed compressor is used with PSC blower.

Another selection provides humidity control by operating the

cooling system when cooling is not required. If the humidity rises

above the dehumidification set point, a special dehumidification

routine is executed. As long as zone temperatures are not more

than 3°F below their cooling set points, a dehumidify demand will

turn on the cooling equipment but will limit its ON time to no more

than 7 minutes at a time.

Finally, OUT zones are used to their maximum capability. When

a zone is set to OUT it can be used to help remove humidity by

cooling it as much as possible. When there is a dehumidify demand

and a zone set to OUT, its damper is fully opened, and it can be

cooled down to as low as 70°F. If it reaches 70°F its damper will

close.

When all zones are set to OUT the house or business is in vacation

mode. The cooling equipment will come on either to maintain the

house or business below 85°F or to maintain the dehumidify set

point by cooling the house or business down to as low as 70°F.

This is a valuable feature for unoccupied homes or businesses in

hot and damp climates.

IMPORTANT: It may be advisable to configure the dehumidify

control as part of the system installation process. Following is a

brief description of the dehumidify setup process. It is also covered

in the Owner’s Manual.

There are 4 selections for dehumidification in the cooling mode:

1. Normal Dehumidify

2. Cool to Dehumidify

3. Vacation Dehumidify

4. OFF

To make a dehumidification selection or change the dehumidify

(dhu) set point, a 2-button keypad press is required. Press SET

TIME/TEMP and FAN buttons simultaneously (indicated on the

keypad by the RH symbol) to enter the humidity mode. Either hu

(humidify) or dhu (dehumidify) will appear on the display. Use

SET TIME/TEMP buttons to select dhu (dehumidify). Now UP

and DOWN buttons may be used to adjust the value of the

dehumidify set point to a value between 50 and 90 percent. One of

the following dehumidification modes may also be selected:

The dehumidify relay is a reverse logic relay. When the humidity

level is above the dehumidify set point, the DHUM relay is off.

When the humidity level is below the dehumidify set point, the

DHUM relay is on.

When in the dehumidification mode, the following can be selected:

1. Normal Dehumidify Mode — This is the factory default.

The dehumidification feature is designed for use with

variable speed indoor equipment. When normal dehumidify

is selected, the compressor will not turn on without a

cooling demand. If a dehumidify demand exists while

cooling, the dehumidify output will be active (i.e. 24vac

removed from DHUM).

2. Cool to Dehumidify Mode — This is selected by pressing

the MODE button to turn on the COOL icon. In selecting

this mode, you are controlling to the rh set point. The cool

to dehumidify feature allows the system to turn on the air

conditioning (i.e. Y output) as needed to try to reach the

selected set point. The equipment will be cycled for

approximately 7 minutes on, and 8 minutes off to control

the humidity. Zone temperatures may be over conditioned

up to 3°F when trying to lower the humidity level. If a

cooling demand exists at the same time as a dehumidify

demand, then the equipment will run until the cooling

demand is satisfied.

3. Vacation Dehumidify — This is selected by selecting the

above cool to dehumidify function (turning on COOL icon),

then exit the humidity program by pressing END key. Next,

press HOLD, OUT, and ALL ZONE buttons in that order to

program all zones to an unoccupied status. The air condi-

tioning equipment will now turn on as needed to control to

the selected dehumidification set point, but it will not drop

the indoor temperature lower than 70°F.

—13—

4. Dehumidify Off — This is used to disable the dehumidify

mode. To turn this function OFF, use UP button to scroll the

set point all the way up. The highest setting will be 90

percent before off (OF) appears in the display. When OF is

displayed, the dehumidification mode is disabled (the

DHUM relay will remain on).

To exit humidity setup mode, press END button, or if no buttons

are pressed for 3 minutes, the User Interface will save and exit this

mode returning to normal operation.

OPERATIONAL INFORMATION

FIVE-MINUTE COMPRESSOR TIMEGUARD

This timer prevents the compressor from starting unless it has been

off for at least 5 minutes. It can be defeated for 1 cycle by

simultaneously pressing the FAN mode button and the UP button.

It is not active in the installer setup mode.

FIFTEEN-MINUTE CYCLE TIMER

This timer prevents the start of the next cycle until at least 15

minutes after the start of the present cycle. Its job is to assure that

equipment is not cycled more than 4 times per hour (or 1 cycle

every 15 minutes). It is defeated for 1 cycle when the desired set

point is manually changed to provide fast response to set point

change. It can also be defeated for 1 cycle by simultaneously

pressing the FAN mode and UP buttons.

STAGING TIMER

In multistage heating or cooling this timer prevents any higher

stage from coming on until the previous stage has been on for 10

minutes. The timer is extended to 15 minutes for heat pump

auxiliary heat and dual fuel furnace operation.

MINIMUM ON TIME

When a cooling or heating stage is turned on, it will remain on for

at least 3 minutes. These timers are canceled when set points are

changed.

HEAT/COOL SET POINT DIFFERENCE

A minimum deadband of 2°F is enforced between heating and

cooling set points. This is done by allowing one set point to "push"

the other to maintain this difference.

AUTO CHANGEOVER

When the auto changeover mode is selected, a change from heat to

cool or cool to heat cannot occur until a demand exists in the new

mode and no demand has appeared in the old mode for 30 minutes

or 10 minutes if option 11 is used. This prevents cycling

continually between heat and cool.

EMERGENCY HEAT MODE

When system is configured for a heat pump and EHEAT mode is

selected, Y outputs are disabled and W outputs only are used for

heat.

POWER-ON CHECK

When power is first applied to the system the large display

indicates the equipment type selected by DIP switches as follows:

1. AC—1-Speed Air Conditioner

2. HP—1-Speed Heat Pump

3. A2—2-Speed Air Conditioner

4. H2—2-Speed Heat Pump

5. AS—1 or 2-Speed Air Conditioner with 3-Stage Auxiliary

Heat

6. HS—1 or 2-Speed Heat Pump with 3-Stage Auxiliary Heat

7. dF—Dual Fuel with 1-Speed Heat Pump

8. d2—Dual Fuel with 2-Speed Heat Pump

OTHER MESSAGES

Small Arrow—A small arrow is located to the left of HEAT and

COOL icons which are located under the two set point displays.

These indicate when cooling or heating equipment is actually

operating. When arrows flash, equipment is waiting to come on but

is being held off by compressor timeguard, cycle timer, or because

LAT or HPT has exceeded its limits and temporarily turned

equipment off.

INITIAL POWER-ON PERFORMANCE

When power is applied to system all dampers are fully opened. As

operation progresses, the system "learns" optimum damper posi-

tions needed to maintain set points in all zones. This learning

process may require up to 2 hours of operation. Allow the system

time to complete its learning.

OVERSHOOT CONTROL

If for any reason a zone is overconditioned by more than 1.5

degrees and the equipment is still operating, that zone’s damper

will close until the overconditioning is less than 1.5 degrees.

TEMPERATURE BALANCING

Under heavy load conditions when the HVAC system does not

have sufficient capacity to maintain all set points, the system does

not automatically open all dampers fully. It continues to control

dampers to keep temperature error in each zone the same as all

others.

VENTILATOR MODE

An automatic ventilation mode is provided by keeping all dampers

at their final position while equipment is off. If the fan is left ON,

more air is supplied to zones which required most conditioning.

Those which required none will have their dampers closed. If 2

hours pass and there is no call for conditioning, all dampers open

fully. In addition, if the mode selection is set to OFF and the fan

selection is set to ON, all dampers will immediately open.

OUTPUTS VS. STAGES

Table 1 lists the active outputs for each stage of each possible

system configuration. G is not shown. It is turned on with any Y.

If installer setup No. 3 is on, G is also turned on with any W.

For 1-stage furnaces and auxiliary heat connect to W1 and leave

W2 open.

For single speed compressors, connect to Y1 and leave Y2 open.

NOTE: Other ways to program comfort schedules with their

function keys can be found in the Owner’s Manual.

→HOLD, OFF, OUT, AND ALL ZONE

The following will provide detailed information regarding HOLD,

OFF, OUT, and ALL ZONE functions: (See Fig. 14.)

A. Hold Function

At the User Interface or Smart Sensor(s):

Pressing HOLD button activates and deactivates HOLD function

for a single zone.

When HOLD function is active, HOLD icon is displayed, and the

current set points will be used until the user cancels the HOLD

function. The HOLD function prevents the set points from

changing according to the program schedule. Cancelling the

HOLD function changes the set points to whatever is in the

program schedule for that period of the day.

B. OFF Function

At the User Interface:

Scrolling the heat set point past its lower limit (40°F), or the cool

set point past its upper limit (90°F) activates the OFF function for

a single zone. When a zone is set to OFF, the set points are

displayed as "OF" and the damper is closed. No conditioning will

be provided to that zone.

To cancel OFF, press UP button to change the heat set point, or

DOWN button to change the cool set point.

When a zone is set to OFF, the HOLD icon will turn on indicating

that OFF is a permanent override. The HOLD icon cannot be

turned off by pressing the HOLD button. However, if HOLD was

turned on prior to turning OFF that zone, then HOLD status will

remain after OFF is cancelled.

The ALL ZONE function cannot be activated from a zone that is

set to OFF.

All zones cannot be set to OFF. If end-user attempts to do this, the

User Interface software will prevent the last zone from going to

OFF.

At the Smart Sensor(s):

Same as above; scrolling the heat set point past its lower limit

(40°F), or the cool set point past its upper limit (90°F) activates the

OFF function for a single zone. When a zone is set to OFF, the set

points are displayed as "OF" and the damper is closed. No

conditioning will be provided to that zone.

C. OUT Function

At the User Interface:

Pressing OUT button activates and deactivates OUT function for a

single zone. When OUT function is active, OUT icon is displayed.

This function programs the zone as being unoccupied.

When OUT function is active, the zone has no set points. The zone

temperature will be kept within the 60-85°F range and if necessary,

the zone will be used as a "dump" zone to relieve LAT problems.

The set points are displayed as "--", and pressing UP and DOWN

buttons will have no effect.

To cancel OUT function, press OUT button and OUT icon will

turn off. Pressing OUT button is a temporary override that will be

cancelled at the next programmed schedule time or by a power

cycle, unless HOLD function is also active.

The OUT function is also a programmable option. You can

program the OUT function in the program schedules.

If a zone is set to OFF, the OUT button will have no effect. OFF

must be cancelled before OUT can become active.

At the Smart Sensor(s):

Same as the above; pressing OUT button will program the zone as

being unoccupied. Pressing OUT button again changes the zone to

occupied. When a zone is set to OUT, the desired temperature will

be displayed as "--" when UP and DOWN buttons are pushed.

D. ALL ZONE

At the User Interface:

Pressing ALL ZONE button activates and deactivates ALL ZONE

function. When the ALL ZONE function is active, ALL icon is

displayed.

This function allows the "entire house or business" to be controlled

to the set points and program schedule of a single zone.

The zone that is displayed when ALL ZONE button is pressed is

the controlling zone. Its set points will be displayed normally. If

the NEXT ZONE button is pressed while ALL ZONE is active, the

room temperature for each zone will be displayed, but the set

points for the non-controlling zones will be displayed as "--".

This function is not available if the zoning has been turned off

through software configuration.

This function is not available if the controlling zone is set to OFF.

At the Smart Sensor(s):

The ALL ZONE function cannot be changed from the Smart

Sensor, but if the function is active, and the Smart Sensor is in a

zone other than the controlling zone, the set point display will

show "--".

If the Smart Sensor is in the controlling zone, then it cannot be

scrolled to OFF.

→TROUBLESHOOTING

A. Error Messages

Several error messages are provided. They appear on the large

display and alternate with the normal room temperature data at a 2

sec rate. These are:

1. E1—COMMUNICATION FAILURE. An E1 will be dis-

played if the User Interface cannot communicate with the

Equipment Controller. Check and make sure V+, Vg, RS+,

and RS- are wired correctly between the User Interface and

Equipment Controller. This error message may sometimes

take up to 30 seconds before it is displayed. After the

problem has been fixed, cycle power to insure that all errors

have cleared.

2. E2—LAT or HPT SENSOR FAILURE. An E2 will be

displayed if the temperature sensor is open, or if it is

reading below -40°F or above 230°F. This error can be

temporarily overridden for troubleshooting purposes only

by turning on configuration option No. 6 in the User

Interface. This will ignore the LAT/HPT sensors while you

—17—

replace the sensors and/or investigate the problem. Dis-

abling this feature should only be temporary. Failure to

properly install the LAT/HPT sensors can cause permanent

damage to the HVAC equipment, as well as lose other

features that the zoning system can provide, e.g., OUT

zone, etc.

3. E3—OUTDOOR AIR TEMPERATURE SENSOR FAIL-

URE. An E3 will be displayed if the outdoor air temperature

sensor is open, or if it is reading below -40°F or above

180°F. This error will also occur if the following features

are active and the Equipment Controller cannot detect the

outdoor air temperature sensor:

Auxiliary Heat Lockout (System is configured as a heat

pump and Option No. 9 is active).

Dual Fuel Setup (DIP switch No. 8 off. System is config-

ured as a heat pump with dual fuel).

Cooling Lockout Below 55°F (DIP switch No. 7 off.

System is configured to disable cooling when outdoor

temperature is below 55°F).

Automatic Humidify Feature (User Interface is setup for

auto-humidify in heating mode).

4. E4—NONVOLATILE MEMORY FAILURE. An E4 will

be displayed if the configuration and program schedules

cannot be read. This is usually the result of a microproces-

sor failure. If cycling power does not reset this error, the

User Interface must be replaced.

5. E5—DEFROST LOCKED. An E5 will be displayed if the

defrost cycle is in process longer than 10 minutes. The

mode will automatically change to the EHEAT mode.

Cycling power will reset error, however, outdoor unit

should be checked to determine if defrost is operating

properly.

6. FF—DAMPER FUSE BLOWN. An FF will be displayed if

the fuse is open or missing. Remove plastic cover on

Equipment Controller to locate and replace fuse.

7. "--" (2 dashes)—TEMPERATURE SENSOR FAILURE.

Two dashes "--" will be displayed if a zone temperature

sensor has failed or is out of range. The User Interface and

Remote Room Sensors are considered failed if the tempera-

ture reading is outside the -40°F to 140°F range. A Smart

Sensor is considered failed if the temperature is outside the

32°F to 140°F range. See Table 4 to determine the

temperature/ohm relationship for a Remote Sensor. Do not

confuse dashes in the display ("--") for a zone that is set to

OUT or ALL ZONE.

OTHER HELPFUL HINTS

Read and understand "System Startup and Checkout" to review

Installer Test Setup Mode and check the equipment operation. This

is a good place to start in evaluating any problems associated with

the zoning system or the system equipment.

TEMPERATURE/OHM RELATIONSHIP

Table 3 shows a temperature/ohm relationship to help aid in

troubleshooting the Zone Perfect Plus System. This table will

evaluate the Remote Sensor, LAT, and HPT sensor operation. Use

a digital multimeter to perform the following:

To verify if a sensor is good, disconnect both leads from I/O board

and measure resistance through the sensor. Match ohm reading to

the table and compare temperature reading on table to ambient

temperature surrounding sensor (accuracy should be +/- 5 to 10

percent).

e.g. If 10.72k ohms are measured, this equals approximately 74°F.

To verify if I/O board is functioning normal, reattach sensor to I/O

board and set meter to 5vdc. Measure voltage across terminal

connections with sensor attached. A typical voltage of approxi-

mately 2.5vdc will indicate I/O board is functioning correctly.
