NOTE: Read the entire instruction manual before starting the
installation.
SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause death, personal injury or property
damage. Consult a qualified installer, service agency or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory--authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing,
and work gloves. Have a fire extinguisher available. Read these
instructions thoroughly and follow all warnings and cautions
included in literature and attached to the unit. Consult local
building codes and the current edition of the National Electrical
Code (NEC) NFPA 70. In Canada, refer to the current editions of
the Canadian Electrical Code CSA C22.1.
Recognize safety information. When you see this symbol on
the unit and in instructions or manuals, be alert to the potential for
personal injury. Understand the signal words DANGER,
WARNING,andCAUTION. These words are used with the
safety--alert symbol. DANGER 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 may result
in minor personal injury or product and property damage. NOTE
is used to highlight suggestions which will result in enhanced
installation, reliability, or operation.
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.
See the IontSystem Zoning Design Guide for more
information on specifying and designing zoning systems.
This instruction covers the physical installation and start up of the
IontDamper Control. Use this instruction to guide the actual
installation process after all the air side decisions have been made.
One Damper Control is capable of handling up to four zones of
operation. When greater than four zones are required, a second
Damper Control Module is needed for zones 5 through 8 (8 zones
maximum).
SNOTE: The IontZoning System IS NOT compatible with all
ICP communicating indoor equipment. For example,
(F,G)9MV and (F,G)8MV two--stage, communicating gas
furnaces are NOT compatible with the IontZoning System.
See the Ion tSystem Control product data for more
information.
SNOTE: Only use modulating dampers provided by ICP for
use with the IontZoning System. Dampers provided by
other companies are NOT compatible with the IontZoning
System.
SNOTE: ObserverrSystem accessories, except for certain
dampers (see damper list), are NOT compatible with the Ion
Zoning System.
Use the Observer rZoning System, or equivalent, for
non--compatible indoor units, such as non--communicating
indoor units, or the (F,G)9MV and (F,G)8MV gas furnaces. The
Observer rZoningSystemmayalsobeusedinretrofit
applications where it is impractical to change existing zone
dampers.
SInstall the IontSystem Control and Remote Room Sensors in
non--condensing areas with ambient temperatures between 32F
and 120F. Install dampers and the IontDamper Control in
non--condensing areas with ambient temperatures between --4F
to 158F(--20to 70C).
SA TXV is required on the indoor coil when used with all
residential split system equipment.
SProper equipment selection and duct sizing are important in a
zoned system. See the Ion Zoning System Design Guide for more
information.
SDO NOT USE a bypass damper with the IontZoning System.
Addition of a bypass will cause improper operation. Airflow
management will be performed by the IontSystem Control
algorithms. The IontSystem Control will monitor the system
and will maintain proper airflow through the heating / cooling
equipment. INTRODUCTION
The IontZoning 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 the Iont
System to change temperature settings in zones to reflect
occupancy or usage. For example, the end user can condition
bedrooms in a home from 5:00 PM through 7:00 AM or the
kitchen from 3:00 PM through 6:00 PM. The IontSystem uses
motorized air volume control dampers (also called zone dampers)
to regulate flow of conditioned air into zones. In this manner, the
system can selectively heat or cool certain portions of a building
depending upon space temperature requirements.
Each zone requires a motorized, modulating zone damper to
control the air supplied to it and a zone sensor to sense temperature
in each zone. There are two types of zone sensors available and
may be used in combination:
SIontSystem Control (p/n SYST0101CW) — Each installation
has only one Master wall/zoning control. This is the command
center for the entire system. It will typically be located in Zone 1
to sense and control the temperature in this zone. If desired, a
Remote Room Sensor may be used to sense the Zone 1
temperature. This can give the installer some flexibility in locating
the Master IontSystem Control wall control to another area.

2
SRemote Room Sensor (p/n SYSTXIIRRS01) — Any zone may
use a Remote Room Sensor (including Zone 1). This is a
temperature sensor only, having no additional user inputs. In
applications where zone temperature averaging may be desired,
this may be done using 4 Remote Room Sensors in a series /
parallel wiring configuration (See Fig. 11 for Remote Room
Sensor Averaging).
Be sure to select the desired sensor type for each zone. Zone sensors
otherthan theIontSystemControlmust bepurchased separately.In-
stallation Instructions for these sensors are included with the sensor.
INSTALLATION
Step 1 — Check Equipment and Job Site
INSPECT EQUIPMENT—File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.
Step 2 — Component Location and Wiring
Considerations
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing sensor, turn off all power to unit. There may
be more than one power disconnect.
!WARNING
NOTE: All wiring must comply with national, local, and state
codes.
LOCATING IONtDAMPER CONTROL
All system wiring is run back to the IontDamper Control. Select
a location near the ICP communicating furnace or fan coil where
wiring from the IontSystem Control, each Remote Room Sensor,
each damper actuator, and the equipment itself can come together
easily.
The IontDamper Control is approved for indoor use only and
should never be installed with any of its components exposed to
the elements. The IontDamper Control (and the zone dampers)
may be installed in any area where the temperature remains
between --4F to 158F(--20Cto70C), and where 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.
It may be mounted in either vertical or horizontal position.
Remember that wiring access is likely the most important
consideration.
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
To prevent possible damage to the IontDamper Control, do
not mount on plenum, ductwork, or flush against surface.
CAUTION
!
LOCATING IONtSYSTEM CONTROL WALL CONTROL
The IontSystem Control is the command center for the Iont
Zone 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 two requirements conflict, a
separate Remote Room Sensor can be added for Zone 1.
When a Remote Room Sensor is connected to Zone 1 terminals
(ZS1 and ZS1C) of the IontDamper Control, the system
automatically switches to using this sensor for Zone 1 and ignores
the sensor within the IontSystem Control. This arrangement
allows the IontSystem Control to be located at any convenient
place within the home or business. In this arrangement, only the
Zone 1 Remote Room Sensor must be located in Zone 1.
NOTE:The IontSystem Control also controls humidity
functions. If the System Control is not used to control Zone 1
temperature, it must still be located in a suitable area where
humidity control will not be affected.
LOCATING SENSORS
For proper operation, each sensor must accurately measure the
temperature within its zone. For accurate temperature
measurement, the following guidelines should be followed:
Sensor should be mounted:
SApproximately 5 ft. (1.5m) from floor.
SClose to the center of its zone, preferably on an inside wall.
SOn a section of wall without pipes or duct work.
Sensor should NOT be mounted:
SClose to a window, on an outside wall, or next to a door leading to
the outside.
SWhere 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.
SClose to or in direct airflow from supply registers.
SIn areas with poor air circulation, such as behind a door or in an
alcove.
WIRING CONSIDERATIONS
Ordinary thermostat wire is ideal when wiring the IontZoning
System (shielded cable is not necessary). Use 20 AWG or larger for
typical installations. Lengths over 100 ft. should use 18 AWG or
larger wire. Remote Room Sensors require only two conductors,
but it is recommended that at least four conductors be run. This
will allow a Smart Sensor (when available) to replace the Remote
Room Sensor with no wiring changes at a later date. The Iont
System Control requires four conductors, each damper actuator
requires three conductors. Cut off or fold back and tape any
unneeded wires. Plan the routing of wiring early to avoid possible
problems later. Remember, all wires converge at the IontDamper
Control, so its location is important.
NOTE: Wiring of the communications bus only requires a
four--wire connection; however, it is good practice to run
thermostat cable having more than four wires in the event of a
damaged or broken wire during installation.
The following color code is recommended for each
communications bus connection:
DX+ — Green = Data A
DX-- — Yellow = Data B
C— White = 24 VAC (Com)
R— Red = 24VAC (Hot)
It is not mandatory that the above color code be used, but each bus
connection in the system MUST be wired consistently.

Step 3 — Install Components
INSTALL IONtDAMPER CONTROL
The IontDamper Control is designed so that wires can enter it
from behind, above, or below. Plan wire routing before mounting
Damper Control.
1. Remove cover to access mounting holes.
2. Mount back plate to wall using screws and wall anchors
provided.
3. Level back plate and tighten screws.
INSTALL IONtSYSTEM CONTROL
See the IontSystem Control Installation Instructions for details.
NOTE: Improper wiring of the communications connector will
cause the IontZoning System to operate improperly. Check to
make sure all wiring is correct before proceeding with installation
or turning on power.
INSTALL REMOTE ROOM SENSORS
1. Separate the sensor cover and mounting back plate by
squeezing the top and bottom of the cover together firmly
by grasping the raised top and bottom ridges. This will re-
lease the cover. Mount to the wall using the screws and an-
chors provided.
2. Pull a 2--conductor wire through hole on right--hand side.
3. Recommended connection is BLACK to either terminal,
WHITE to remaining terminal (sensor terminals are not
marked for polarity because polarity is not important).
Stranded or common bell wire may be used. Lengths up to
1000 ft. will contribute no noticeable error.
4. Push any extra wire into the wall and seal the hole to pre-
vent air leaks. Align the sensor cover with the base plate,
then press firmly until the cover snaps into place.
Step 4 — Install Zone Dampers
NOTE: Only use modulating dampers provided by ICP for use
with the Ion Zoning System. Dampers provided by other
companies are NOT compatible with the Ion Zoning System.
Proper selection and sizing of dampers is very important for proper
system operation. Be sure to consult the IontSystem Control
Product Data Sheet and IontZoning Design Guide for assistance
in making these selections. Selection and sizing information is not
provided in this installation instruction. Zone dampers are available
in round, rectangular, and slip--in design, and may be installed in
any position, except, avoid placing the actuator directly below the
ductwork if condensation on or within the duct is expected. Install
the damper so that the actuator is visible for inspection and
accessible in the event it would need to be serviced. The black
mark on the end of the damper shaft represents the position of the
damper blade. To wire the damper, locate the terminals labeled:
OPN (open); COM (common); CLS (closed; and wire
appropriately (see Fig. 1 for Damper 24 VAC connection).

If the duct system requires multiple dampers for a single zone, up
to five dampers (maximum) may be wired in parallel. DO NOT
use dampers with crank--arm style actuators.
If an actuator is removed from a damper for any reason, it must be
properly aligned when it is reinstalled. This can be done by
rotating the actuator and the blade to their closed positions and
then tightening the actuator (set screw) to the shaft. This assures
alignment at the closed position. (Pressing the quick blade release
button allows the actuator to be manually turned.)
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Condensation can damage the actuator. When dampers are
located in an unconditioned space, condensation is likely to
occur in cooling. To prevent condensation and losses, all
dampers and ductwork in unconditioned space must be
insulated or otherwise protected.
CAUTION
!
Do not mount the dampers with their actuators hanging directly
beneath the ductwork. It is best to mount the actuator facing in
either the three or nine o’clock position.
For specific duct types, follow the instructions below:
NOTE: All zone dampers and ductwork must be properly
supported according to local codes or SMACNA standards.
ROUND METAL DUCTWORK
1. Crimp the end of the branch duct.
2. Slip the end of the zone damper over the ductwork end. Use
a self--tapping sheet metal screw to secure.
3. Properly seal the joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with the actuator.
4. If dampers are applied in an unconditioned space, insulate
themusing1--1/2inchto2inchinsulation(SeeFig.2).

Step 5 — Final Wiring
Bring all damper and sensor wires together at the IontDamper
Control. Make all system wiring connections as shown in Fig. 9.
The two communications bus connections on the IontDamper
Control are in parallel with each other. Use either terminal block to
connect the IontSystem Control, Smart Sensor(s) (when
available), variable--speed indoor unit and 2--speed communicating
outdoor unit (if applied). If more than four zones are required (up
to 8 zones maximum), see Step 6 and Fig. 10 for additional
Damper Control Board Setup for Zones 5--8.

LEAVING AIR TEMPERATURE / HEAT PUMP TEMPER-
ATURE (LAT / HPT) SENSORS
These inputs on the IontDamper Control are used only for
diagnostic purposes and NOT required for regular use.
Traditionally, the LAT/HPT sensors were required for temperature
and equipment monitoring. The IontZoning System does not
require these because the IontSystem Control algorithms will
perform temperature and airflow management without the use of
these sensors. If desired, one or both sensors may be used to
monitor leaving air temperature and/or indoor coil air temperature.
Consideration and/or flexibility will now permit using one of these
sensors in the return air duct giving the dealer an option to view
both entering and leaving air temperature at the IontSystem
Control. If applied, connect sensors to the LAT / HPT terminals
(See Fig. 9, System Wiring, for connection to the IontDamper
Control). LAT is monitored by both AC and HP systems. LAT and
HPT are both monitored only in HP systems.
To install -- Locate the LAT sensor in the main supply trunk after
the heating and cooling coil and before the first branch. The LAT
sensor is radiant shielded to prevent heat from affecting correct air
temperature.
1. Drill a 1/4 inch hole at the location in the supply trunk
where the sensor will be installed.
2. Insert the sensor in the hole and use it as a template to mark
the two mounting holes.
3. Drill two 1/16 inch holes to accept #6 screws through pre--
drilled holes in the duct temperature sensor backplate.
4. Use two #6 sheet metal screws to mount the duct tempera-
ture sensor to the unit.
5. Connect the sensor to 2--conductor wire using the provided
wire nuts.
The HPT sensor (in heat pump applications) measures the
temperature of the air leaving the indoor coil. The sensor is
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).
LED INDICATORS
Under normal operation, the Yellow and Green LEDs will be on
continuously (solid). If the IontDamper Control does not receive
communications with the IontSystem Control, the Green LED
will not be on. If there are faults present, the Yellow LED indicator
will blink a two--digit status code. The first digit will blink at a fast
rate, and the second at a slow rate.
STATUS CODE DESCRIPTION
16 = Communication Failure
24 = Damper Fuse Failed
45 = Board Failure
46 = Low Input Voltage
FUSE
A 1A automotive type fuse is used to protect the IontDamper
Control from over current on the damper drive outputs. If this fuse
fails, the damper wiring should be inspected for shorts. Also, no
more than five damper motors should be connected to a single
damper output. The fuse should always be replaced with an
identical 1A automotive type.
Step 6 — Additional Damper Control Board Setup
If you have more than four zones, a second IontDamper Control
must be used and both dip switch settings on the second board
supporting zones 5 through 8 must be moved to the right. The
communications bus connector must be wired between both Iont
Damper Controls.
Step 7 — Transformer Requirements
The IontZoning System drives only two zone damper outputs at
a time. As a result, up to eight zones each with up to five dampers,
plus a smart sensor (when available), can be handled without
increasing the size of the system transformer or adding a second
zoning transformer.
Use of the transformer provided in the furnace or fan coil is
recommended without change in all zoning applications.
For those who still want more transformer capacity, a 60 VA
system transformer may be used in place of the supplied 40 VA
part. Note that if more power for the communicating system is
desired, use a field--installed, Class 2, 24VAC transformer. Remove
the ”C” and ”R” power connections from the indoor unit
communication bus connector. Connect the communication bus C
and R connections at the IontDamper Control to the
field--installed transformer to power the communication system.
Step 8 — System Start--up
Follow the system start--up process outlined in the IontSystem
Control Installation Instructions for details.

TROUBLESHOOTING
IontSystem Control does not power up:
1. Recheck the wiring to the communications connector on all
devices. Make sure all colors match for every terminal.
2. Make sure power is applied to the indoor unit, and the Yel-
low and Green LEDs are lit on the IontDamper Control.
3. Check for 24 VAC between the C and R terminals at the
IontSystem Control terminal block. See the Transformer
Requirements section if load issues on the indoor unit trans-
former is suspected.
4. Check the fuse at the indoor unit circuit board, and the
IontDamper Control.
IontSystem Control display says “Indoor Unit Not Found:”
1. Recheck the wiring to communications on all devices. Make
sure all colors match for every terminal.
2. Press the side button at the IontSystem Control to try
again.
3. Check for power to the indoor unit. If a field--supplied
transformer is used to power the communication, make sure
that power source is connected and powered.
4. Disconnect all communications connections from every de-
vice and only reconnect the IontSystem Control to the in-
door unit (and field--supplied transformer, if applicable). If
the indoor unit is identified by the system control, then an-
other device on the communications connection may be at
fault. Reconnect each device’s communications connection
one at a time and perform a Re--Install from the Service
Menu after each connection is made. If one or more devices
are not found after reconnecting the last device, the last de-
vice may be suspect.
5. If the communications connection only contains an indoor
unit and an IontSystem Control, then the wiring, indoor
unit control board, or IontSystem Control may be at fault.
IontSystem Control cannot find Zones 5 -- 8:
1. Make sure zone module 5 -- 8 has the dip switches set to the
far right.
2. Recheck the wiring to the communications connections.
IontSystem Control can find zones 5 -- 8, but not 1 -- 4:
1. Make sure zone module 1 -- 4 has the dip switches set to the
far left.
2. Recheck the wiring to the communications connections.
Zone dampers do not move:
1. Check the fuse located on the IontDamper Control. If the
fuse is failed, check the damper wiring and inspect for
shorts. No more than five damper motors should be con-
nected to a single damper output. The fuse should be re-
placed with an identical 1A automotive type.
2. Use the System Checkout procedure (refer to the Installa-
tion Instructions) to test the zoning dampers and to verify
that the correct set of dampers is opening for each zone.
3. Dampers may be powered directly—for testing purposes
only—by connecting 24VAC directly across Com and
Open, or Com and Close. The damper should open or
close, based on which input is being powered. This will
rule out the damper.
