NOTE: Once the Infinity Touch Control is secured to wall with the backplate
assembly (snapped together), care must be taken not to bend or break the
interlocking tabs when removing.
4.6. Humidifier Connections
A 24VAC bypass or fan powered humidifier may be installed.
NOTE: Do NOT use a traditional humidistat to control humidifier operation. If a
humidifier is installed, let the Infinity Touch Control operate humidifier.
4.6.1. Bypass Humidifier
A bypass humidifier should be wired directly to the furnace or fan coil HUM and
24VAC COM terminals. The Infinity Control Touch will automatically energize the
HUM output during a call for humidification.
4.6.2. Fan Powered Humidifiers
Most fan powered humidifiers produce internal 24VAC in order to energize upon a
switch or contact closure. For this application, a 24VAC N.O. Isolation Relay
(DPST) MUST be used to prevent mixing the internal humidifier power with the
indoor equipment transformer. Applying 24VAC isolation relay coil to furnace or
fan coil HUM and COM terminals will allow the Infinity Touch Control to 
						

							14
automatically energize the HUM output during a call for humidification. The N.O.
relay contacts will be used to energize the humidifier. See fan powered humidifier
installation instructions for more details.
5. Commissioning
This section addresses initial power up (or commissioning) of a new Infinityr
Touch Control. The control will communicate and identify all components in the
InfinityrSystem. The following is a typical example for a communicating
variable --speed furnace / fan coil with a 2 --stage air--conditioner / heat pump
(including HYBRIDHEATrdual fuel system).
5.1. Searching for Indoor Unit
The Infinity Touch Control will light up and begin the commissioning process by
displaying “Searching for indoor unit”.
A12177
NOTE: If the variable --speed indoor equipment (furnace or fan coil) cannot be
found, the control will display “Indoor unit not found”. ThisMUSTbe corrected
before the initial power up sequence can continue. Proceed to the next section,
Searching for outdoor unit. If it is not corrected, the Infinity Touch Control will go
into itsDEMOoperating mode. 
						

							15
A12178
5.2. Searching for Outdoor Unit
The Infinity Touch Control will then proceed to communicate with the outdoor unit
by displaying “Searching for outdoor unit”.
NOTE: If the outdoor unit cannot be found, the control will display “Outdoor unit
not found”.
SSelect the appropriate unit installed; then, touchNEXT.
dAC1Stage– 1 --stage air conditioner
dAC2Stage– 2 --stage air conditioner
dHP1Stage– 1 --stage heat pump
dHP2Stage– 2 --stage heat pump
dNone– No outdoor unit installed
SThe installer will first be instructed to select the appropriate size of the outdoor
unit; then, touchNEXT.

A12183
5.3. Indoor Evaporator Selection
If a furnace is installed with a variable capacity heat pump, a screen will appear to
select the installed indoor evaporator coil. This selection is used to adequately
calculate the refrigerant charge required while in the heat pump charging screens
under the Heat Pump Checkout menu (See page 44). Select “other” for non --Carrier
evaporators.
5.4. Electric Heater Selection
If the indoor equipment is a fan coil, the control will display “Searching for heater”
until one is found. If the electric heater is not self--identifying, the select heater
screen will appear. Touch the appropriate heater size; then, touchNEXT. 
						

							17
A12184
5.4.1. Hydronic Heat Application
The Infinity Touch Control supports 2 types of Hydronic Heat applications:
1. Hot water coil in combination with an FE fan coil and heat pump, or hot
water coil as sole heat source with an FE fan coil.
2. Non --zoned FE fan coil combined with radiant hot water heat.
In either application, a Hydronic Heat kit should be installed in place of an electric
heater. See FE fan coil Product Data for accessory part number. The system will
self--identify that hydronic heat has been installed during electric heater selection.
The system will treat the hot water coil as either auxiliary heat in a heat pump
application, or the sole heat source. Setup options for Hydronic Heat applications
are described in the setup section of this instruction.
5.5. Searching for Zones (if applicable)
“Zoning -- Searching” will appear on the screen to determine if any zones are
present. The screen will show Zone 1, Zone 2, etc. and indicate all zones having
either a Remote Room Sensor, or smart sensors associated with them. If the system
contains smart sensors, they must be assigned a zone number before continuing.
See the Smart Sensor Installation Instructions on how to assign Smart Sensors to
their respective zones. After each zone has been identified, touchNEXT. 
						

							18
A12185
5.6. Filter Type Selection
The installer will next be prompted to select the air filter type installed with the
Infinity System. After the selection is made, touchNEXT.
SAir Filter: 1 --in. to 4 --in. media filter
SEAC: high voltage electronic air cleaner
SAir Purifier: Infinityror PerformancetAir Purifier
5.7. Humidifier Installation
Next, the installer will be prompted to select whether a humidifier is installed in the
system. SelectYESorNO, then touchNEXT.
5.8. Ultraviolet Lights Installation
Next, the installer will be prompted to select whether ultraviolet lights are installed
in the system. SelectYESorNO, then touchNEXT.
5.9. Equipment Summary
The equipment summary screen will appear after accessories have been selected.
This screen will give a summary of all equipment automatically found or manually
selected. If an incorrect selection was made, touchRE-- INSTALLto go back to 
						

							19
that particular screen and make changes. When everything is OK, touchNEXTto
continue.
A12144
5.10. Static Pressure Check
The static pressure check screen will appear next. The system will perform a static
pressure check. This process will take about 1 --1/2 minutes to complete. When
completed, a screen will appear displaying the static pressure (in inches) across the
equipment at the expected highest delivered airflow. If the blower RPM is greater
than 1200, then a warning will appear, but equipment operation and the
TrueSensetdirty filter detection operation will not be affected. When the static
pressure check is complete, touchNEXT.
NOTE: The static pressure check occurs only at initial installation, or when
INSTALLisrunintheINSTALL/SERVICEmenu.
5.11. Duct Assessment (zoning applications only)
The duct assessment screen will be displayed next for zoning applications. Touch
NEXTto start Duct Assessment. Duct Assessment will measure the relative size of
the ductwork, up to and through the dampers. These measurements are used to
control the correct amount of airflow in the zoned system. Status messages will
appear on the screen to indicate what the system is doing. The process will take 
						

							20
approximately one minute per zone. The duct assessment will override a call for
heat or cool.
A duct assessment will automatically occur each day at a user selectable time. The
factory default time is 1:00 p.m. but, may be changed by entering the Zoning Setup
menu (see pages 36 -- 37). If there is an active call for heating or cooling, the
system will wait until the call is satisfied before it performs the duct assessment.
The system will first open all zones and drive the blower to 175 CFM/ton of cooling
(or the minimum indoor unit’s airflow, whichever is greater). It will then take a
static pressure measurement. The system will then close all zones and open one
zone at a time, taking a static pressure measurement for each zone.
The system will then close all zones and take a pressure measurement, getting a
value for the duct leakage up to and through the dampers. With these static pressure
measurements, the system will calculate the relative size of each zone as well as the
percent leakage through the dampers At the end of the process, the display will
show the relative size of each zone duct.
If the Infinity Touch Control detects an error (damper not moving or damper wired
backwards), it will perform the duct assessment again. If it still detects a damper
problem, it will default the measurements into equal sizes, with 10% leakage, and
display the zone number for the suspected zone damper.
After the duct assessment is complete, touchNEXT.
