before removing cover

from Thermostat.

IMPORTANT

Do not remove battery tags to activate the

thermostat or wireless sensor until instructed to

do so.

For proper operation of the RF wireless

communication, when installing:

zAvoid locating thermostat or sensor near any

wireless or noise generating devices, particularly

radio devices that operate in the range of 418 to

428 MHz.

zBe sure that there are no electrical wires, metal

pipes or ductwork in the part of the wall chosen for

thermostat or sensor location

zAvoid locating the thermostat or sensor on a

concrete wall, metal junction box or metal plate.

zThermostat antenna wire must be installed into the

wall.Do not allow the antenna wire to be between

the thermostat and the wall.

zThermostat must have uninterrupted 24VAC for

proper communication.

System Power

Thermostat is received from the factory for system

power to be hardwired with a common wire connected to

terminal C. If no common wire is available, the thermo-

stat will use Power Stealing and must be configured.

See Thermostat 24VAC Requirement on page 5.

This device complies with Part 15 of the FCC Rules.

Operation is subject to the following two conditions:

(1) this device may not cause harmful interference, and

(2) this device must accept any interference received,

including interference that may cause undesired

operation.

Refer to Thermostat Configuration beginning on

page 10. If the remote sensor is to be an indoor

sensor, on Step 4, change Remote Off to Remote

On to enable the indoor sensor.

When the configuration menu is exited, the display

will indicate the indoor sensor is enabled.

4Provide battery power to remote sensor

and check sensor transmission

Connect wires to thermostat

Connect wires following standard wiring procedures.

Questions on wiring, see system diagrams on page 7.

24 VAC Requirement

The thermostat must have 24VAC to operate. If a

common wire is connected to terminal C, the

system is providing 24VAC to the thermostat and

the RC/PS switch (S7) should be in the RC posi-

tion. (See Figure 1 on page 5) Proceed to step 3.

If the thermostat does not have a common wire

connected to terminal C, the RC/PS switch must be

in the PS position to allow Power Stealing.

Antenna Wire – When installing the thermostat,

antenna wire must be installed into the wall for

proper communication between the thermostat

and the remote sensor.

Now, remove Battery Tag only from remote sensor

to provide power. Do not remove Battery Tag from

thermostat.

Enable the Learn mode of the remote sensor to

confirm that remote sensor is transmitting and

thermostat is receiving. Press and keys at

the same time and hold for approximately five

seconds. When keys are released, display will

show OFF and Learn. Press to change OFF to

ON. Then press both keys at the same time three

more times to exit the menu. The remote sensor

will be in the Learn mode and will transmit once

every 10 seconds for 10 minutes.

Place the sensor on the thermostat for the best

transmitting-receiving conditions.

Do not remove battery tags to power the thermostat or sensor

with batteries until instructed to do so. The thermostat requires

24voltsystem power to operatecorrectly.Leavingthebatteries

disconnected during installation and check out will verify sys-

tem power is present. If the thermostat goes blank, system

power is not reliable and will be corrected in the System Power

section below.

1. Remove the packing material from the thermostat and

sensor.

2. Pull the front cover of the thermostat straight off the base.

Forcing or prying will cause damage to the control.

selected wall locations and mark the location of all

mounting holes (Figure 1), and the hole for the thermostat

antenna wire illustrated in Figure 2.

4. Move base out of the way and drill the holes. If mounting

holes drilled are too large and do not allow you to tighten

base snugly, use the plastic screw anchors (provided) for

secure mounting.

5. Make sure the remote communication receiver is

plugged in properly to the thermostat and that the

antenna wire is routed through the thermostat subbase

as shown in Figure 2.

6. Insert antenna wire into the wall and position base into

mounting position.

7. Fasten base loosely to wall, using two mounting screws.

Place a level against bottom of base (leveling is for

BatteryLocationBatteryLocation

BatteryLocation

The thermostat requires 2 "AA" alkaline batteries and the

sensor requires 2 "AAA" alkaline batteries. Batteries are

included at the factory with a battery tag to prevent power

drainage. The battery tag must be removed to engage the

batteries. For best results, replace batteries once a year with

new premium brand alkaline batteries such as Duracell®or

Energizer®.

Electric/Gas Switch (Fan Option)Electric/Gas Switch (Fan Option)

Electric/Gas Switch (Fan Option)

The ELEC/GAS switch on the thermostat (Fig. 1) is factory

set to the ELEC position. In this position, the thermostat will

power the circulator fan on a call for heat. Electric heat

systems may require the switch to be in the ELEC position.

If your system does not require that the thermostat power the

circulator fan, this switch should be set to the GAS position.

Typically, gas and oil heating systems do not require the

thermostat to power the circulator fan during a call for heat. If

your heat is gas or oil, the switch should be set to the GAS

position.

When the thermostat is configured for Heat Pump, the

thermostat will always power the circulator fan on a call for

heat in the HEAT mode. The ELEC/GAS switch must be set

to match the type of Auxiliary heat your system uses for

proper operation in the EMERgency mode.

Typical wiring diagrams are provided below for the following systems:

Single Stage Heat/Cool systems

Multi-Stage Heat/Cool systems (No Heat Pump)

Heat Pump system, one compressor or one speed compressor with Aux. Heat

Heat Pump systems, two compressors or two speed compressor with Aux. Heat

Refer to the equipment manufacturers instructions for specific wiring information. After completing the connections configure

the thermostat in the Installer Configuration Menu to match your system type.

equipment operates on the same frequency. The interfer-

ence may degrade the communications between the

sensor and the thermostat. To avoid interference, you

may select a different radio frequency for your sensor.

This menu item allows you to select a radio frequency

offset from 1 to 9MHz from the base frequency. For

example; if you selected an offset of 4, the transmitter

radio frequency will be 418MHz + 4MHz = 422MHz. Note

that the sensor’s transmitter and the thermostat’s receiver

must operate on the same frequency to communicate. To

change thermostat’s receiver frequency please refer to

Thermostat Configuration Menu (Item 6).

Second Stage Time DelaySecond Stage Time Delay

Second Stage Time Delay

Your thermostat is designed to determine the optimum time

to activate the second stage. Simply raising the temperature

in heating or lowering it in cooling will not always force the

thermostat to bring the second stage on quickly. If the fast

second stage option in the configuration menu (step 12) is

set to "OFF", there is a delay from 0-30 minutes depending

on the performance of the first stage of the system.

EXAMPLE: For the last 2 hours the thermostat is set on 70°

and the room temperature is 70° with the equipment using

only the first stage of heat. Since the equipment is keeping

the temperature within 1 degree of setpoint, the thermostat

will delay second stage for a longer time if you manually

raise the temperature or if the room temperature quickly

changes. Once the second stage comes on, it will come on

sooner the next time there is a difference between the

setpoint and the room temperature. The net effect of the

staging program is that when the first stage is capable of

holding temperature, the second stage will delay longer.

When the thermostat calculates that first stage cannot make

temperature in a reasonable time, the second stage will

come on sooner. This built in function automatically opti-

mizes the use of additional stages of heat or cool.

LearLear

Your thermostat is configured at the factory to recognize the

wireless remote sensor shipped with it. This sensor is stored

as Sensor A. The Learn Mode Option must be performed on

the thermostat and wireless remote sensor if:

• A wireless remote sensor is added to another channel.

• The wireless remote sensor is replaced.

• The thermostat is replaced.

• The thermostat has been reset using ,,

SYSTEM keys.

During the Learn Mode, the wireless remote sensor will

transmit identification information every ten seconds for ten

minutes. In this ten-minute period, the display will show

“LEARN” and the antenna icon will show for a short time with

each transmission. The thermostat will be receiving the

transmitted identification information.

To perform the Learn Mode on the thermostat and sensor:

Remove the batteries from all wireless remote sensors in

the same building except the sensor you are going to put

into the Learn Mode. This will prevent interference from

the other sensors.

TemperatureAveragingTemperatureAveraging

TemperatureAveraging

Your thermostat is designed to sense the temperature of

the indoor remote sensor and average or weight it with the

local sensor in the thermostat for each program period. The

averaging will only be active when both the local and the

indoor remote sensors are functional and turned on in the

configuration menu. When the thermostat is placed in view

schedule mode (press PRGM once), the weight of the

indoor remote sensor will be shown on the left side of the

display when HOLD button is pressed. The weighting

classes of the indoor remote sensor are designated as A

(default for average weight), HI (high weight), or LO (low

weight). The HI weight is two times the weight of the average

weight. The Aweight is two times the weight of the LO

weight. The weight of the local sensor is fixed to A(average

weight). The actual temperature displayed, in the clock

digits, in the normal operation mode is the mathematical

weighted sum of the enabled functioning sensors. For

example, if the local sensed temperature is 80°F and the

remote sensed temperature is 70°F then:

If weight selected is HI , then the averaged temperature is

(2 x (80°F) + 4 x (70°F))/ 6 = 73.3°F.

If weight selected is A, then the averaged temperature is

(2 x (80°F) + 2 x (70°F))/ 4 = 75°F.

If weight selected is LO , then the averaged temperature is

(2 x (80°F) + 1 x (70°F))/ 3 = 76.6°F.

The example above shows that the weight selected would

prioritize the overall averaged temperature between the two

sensors. The high weight selection caused the remote

sensor to carry more weight in the calculated temperature

average than the local sensor. The low weight selection

caused the remote sensor to carry less weight in the

calculated temperature average than the local sensor.

stat when the temperature changes 3/16 degree or more

from the last update. If the temperature does not change for

10 minutes, the sensor will transmit to assure communica-

tion.

BATT icon to indicate a low battery power

condition. The 2 "AAA" batteries must be replaced to ensure

a proper sensor performance. For optimum performance,

replace batteries once a year with new premium brand

alkaline batteries such as Duracell®or Energizer®.

Increasing the sensor Comfort graph toward H decreases

the displayed remote temperature shown on the thermostat

by 1°F per bar. This will lower the actual calculated room

temperature by up to 4°F. Decreasing the sensor Comfort

graph toward C increases the displayed remote temperature

and will raise the actual calculated room temperature. The

set to PS), the thermostat draws a small

amount of power through the heating

circuit to operate. Some furnace

systems using high impedance input

electronic modules may react to the

current draw and actuate system

components.

Reset OperationReset Operation

Reset Operation

If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermo-

stat by removing the wires from terminals R and C and removing batteries for 2 minutes. After resetting the thermostat,

replace the wires and batteries. If the thermostat has been reset and still does not function correctly contact your heating/

cooling service person or place of purchase.

Pressing

and and the SYSTEM keys at the same time will reset the thermostat to its factory default setting. This will

also clear any limited temperature ranges or keypad lockout settings. Note default system configuration is multistage system

operation.

Re-light pilot.

Set SYSTEM Switch to HEAT and raise setpoint

above room temperature.

Verify thermostat and system wires are securely

attached.

Many furnaces have safety devices that shut down

when a lock-out condition occurs. If the heat works

intermittently contact the furnace manufacturer or

local service person for assistance.

Diagnostic: Set SYSTEM Switch to HEAT and raise

the setpoint above room temperature. Within a few

seconds the thermostat should make a soft click

sound. This sound usually indicates the thermostat

is operating properly. If the thermostat does not

click, try the reset operation listed above. If the

thermostat does not click after being reset contact

your heating and cooling service person or place of

purchase for a replacement. If the thermostat clicks,

contact the furnace manufacturer or a service

person to verify the heating is operating correctly.

Set SYSTEM Switch to COOL and lower setpoint

below room temperature.

Verify thermostat and system wires are securely

attached.

Same procedure as diagnostic for No Heat condi-

tion except set the thermostat to COOL and lower

the setpoint below the room temperature. There

may be up to a five minute delay before the

thermostat clicks in Cooling.

Verify that the AM or PM settings are correct for

each program period and the current time of day.

Also verify the Day of the week is set correctly.

The EMR (Energy Management Recovery) feature

starts early to achieve the temperature it is pro-

grammed for by the time specified in the program.

See the Configuration Menu section to disable

EMR if you do not want the thermostat to start early.

1. Add a common connection from the system

transformer to the "C" terminal on the thermostat

and set the RC/PS switch to RC.

2. If the system has a standard cooling contactor

and no common connection is available at the

thermostat, clip jumper W25-W1 and separate the

ends. This prevents the thermostat from drawing

power from the W1 (heating) circuit. If the

condition persists after clipping the jumper, a

heating and cooling service person can install an

isolation relay to the system or add a common

wire as mentioned above.

Possible Cause

1. Loss of power from heating/cooling

system to thermostat.

2. Remote sensor too far from

thermostat.

3. Thermostat or remote sensor set to

different channels or a different

frequency offset.

4. Incorrect sensor identification

selected.

5. Replacement Sensor requires

running learn mode.

6. Remote sensor requires replace

ment.

1. Improper system sizing or improper

heating and cooling distribution

between areas.

2. An uneven change in occupancy

level, sun load or conditioned space

activities (cooking, washing dishes,

showers, etc.) between the areas.

1. Possible short in wiring.

2. Possible short in thermostat.

3. Possible short in heat/cool/fan

system.

4. FAN Switch set to Fan ON.

1. The location of the thermostat and/or

the size of the Heating System may

be influencing the cycle rate.

1. Thermostat thermometer setting

requires adjustment.

1. Voltage spike or static discharge.

1. The desired setpoint conflicts with the

setpoint of the COOL mode.

1. The desired setpoint conflicts with the

setpoint of the HEAT mode.

Corrective Action

1. Verify the thermostat is operating on AC power by

removing the thermostat batteries. If display goes

blank, AC power is lost.

2. Change remote sensor location.

3. Verify the thermostat and remote sensor are set

to the same channel and frequency offset.

4. For indoor sensor, verify sensor identification

selected is A, B or C. For an outdoor sensor,

verify the sensor identification selected is O.

5. If the sensor did not come with this thermostat

from the factory, perform the learn procedure for

thermostat and sensor.

6. If the sensor display indicate E0 or E1, replace

the remote sensor.

Selecting a high or low priority for the thermostat

or sensor location during program periods can

help even out minor temperature imbalances

between the thermostat and remote sensor

locations. This is also useful for scheduled or

predictable events like occupancy level or sun

load during particular times of the day. If the

temperature difference remains large after

assigning priorities, system modification or

zoning may be necessary to balance the tem-

perature distribution.

Check each wire connection to verify they are not

shorted or touching together. No bare wire should

stick out from under terminal screws. Try resetting

the thermostat as described above. If the condi-

tion persists the manufacturer of your system or

service person can instruct you on how to test the

Heat/Cool system for correct operation. If the

system operates correctly, replace the thermostat.

Digital thermostats normally provide precise

temperature control and may cycle faster than

some older mechanical models. A faster cycle

rate means the unit turns on and off more

frequently but runs for a shorter time so there is

no increase in energy use. If you would like to

increase the cycle time, choose SL for slow cycle

in the menu, step 4. If an acceptable cycle rate is

not achieved as received or by choosing slow

cycle, contact a local service person for additional

suggestions.

The thermometer can be adjusted +/- 3 degrees.

See Temperature Display Adjustment in the

Configuration Menu section.

Use the Reset Operation at top of previous page.

Change system mode to COOL. Raise the Cool

setpoint. Return to HEAT mode and set desired

temperature.

Change system mode to HEAT. Lower the Heat

Your thermostat is designed to determine the

optimum time to activate the second stage. Simply

raising the temperature in heating or lowering it in

cooling will not always force the thermostat to bring

the second stage on quickly. There is a time delay

from 0-30 minutes depending on the performance

of the first stage of the system.
