1. 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 o r 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.

2. Introduction

The Infinityr System consists of several intelligent communicating components
which includes the Infinityr Touch Control (or User Interface), variable speed
furnace or FE fan coil, and 2--stage AC or HP, which continually communicate with
each other via a four--wire connection called the ABCD bus. Commands, operating

2

conditions, and other data are passed continually between components over the
ABCD bus. The result is a new level of comfort, versatility, and simplicity.

All Infinityr furnaces or fan coils are variable--speed and multi stage for maximum
flexibility, efficiency, and comfort. They support controlled ventilation,
humidification, dehumidification, and air quality control. Either an Infinityr
(communicating), or a standard single--stage 24VAC controlled outdoor unit may be
used.

When using conventional single--stage outdoor units, the Infinity furnace or fan coil
provides the 24 volt signals needed to control them. Also, the Infinityr Network
Interface Module (P/N SYSTXCCNIM01) allows connection of a Carrier HRV or
ERV without the need for separate wall control.

When using a Carrier HRV or ERV with a zoned system, the Infinityr Zone board
allows connection of a Carrier HRV or ERV without the need for separate wall
control.

All system components are controlled through the wall mounted Infinity Touch
Control, which replaces the conventional thermostat and provides the homeowner
with a single wall control for all features of the system.

4. Installation

4.1. Overview

This instruction covers installation of the Infinityr Touch Control and the Infinityr
Wireless Access Point only. Physical installation instructions for the indoor and
outdoor equipment, and accessories are provided with each unit.

Setup, commissioning, operation, and troubleshooting of the Infinityr System are
covered only in this installation instruction. It is the guide to connecting the system
components and commissioning the system once all physical components are
installed. Special screen prompts and start--up capabilities are provided in the
Infinityr System to simplify and automate the initial commissioning of the system.

S Install the Infinity Touch Control according to this instruction.
S Install indoor unit, outdoor unit, and accessories according to their instructions.
S Wire complete system according to this instruction.
S Setup, commission, and operate system according to this instruction to assure a

smooth and trouble free start--up.

4.2. Check Equipment

Inspect equipment. File a claim with shipping company prior to installation if
shipment is damaged or incomplete.

5

4.3. Location

ELECTRICAL OPERATION HAZARD

Failure to follow this warning could result in personal injury
or death.

Disconnect power before routing control wiring.

!

WARNING

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

4.3.1. Wall Control

The Infinity Touch Control is the command center for the Infinity System. It should
be located where it is easily accessible and visible to the adult homeowner or end
user. For accurate temperature measurement, the following guidelines should be
followed:

The Infinity Touch Control and Remote Room Sensors SHOULD be mounted:

S Approximately 5--ft (1.5 m) from the floor.
S Close to or in a frequently used room, preferably on an inside partitioning wall.
S On a section of wall without pipes or ductwork.

The Infinity Touch Control and Remote Room Sensors SHOULD NOT be
mounted:

S Close to a window, on an outside wall, or next to a door leading to the outside.
S Exposed to direct light or heat from a lamp, sun, fireplace, or other

temperature--radiating objects which could cause a false reading.

6

S Close to or in direct airflow from supply registers.
S In areas with poor air circulation, such as behind a door or in an alcove.

4.3.2. Remote Room Sensors

A Remote Room Sensor can be used with the Infinity Touch Control to take the
place of the control’s internal temperature sensor. This allows the Infinity Touch
Control to be mounted in areas with less than optimal airflow (such as near an
exterior door, window or in a closet). The remote sensor can be wired to the
terminal block connectors labeled S1 and S2 at the control’s backplate, or the ZS1
and ZS1C connection at the Damper Control Module. In either case, the Infinity
Touch Control will automatically detect the Remote Room Sensor and ignore its
internal temperature sensor.

4.3.2.1. Remote Room Sensor Averaging

Typically, one remote sensor is used but, multiple sensors may be used and
averaged in some applications. Averaging requires a special series --parallel wiring
method with a specific number of sensors. See figure below. It is also important to
note the humidity sensor cannot be remotely located, so do not locate the Infinity
Control in an area where humidity sensing may not be accurate.

4.3.3. Smart Sensors (for zoning applications)

Any zone may use a Smart Sensor. It provides a temperature display and buttons to
adjust the desired temperature in that zone only. It also displays outdoor
temperature and indoor humidity sensed at the control. Only one Smart Sensor may
be used per zone. They cannot be averaged like Remote Room Sensors. If a Smart
Sensor is used in a zone, a Remote Room Sensor may also be used in the same
zone. The Remote Room Sensor has priority over the Smart Sensor. The Smart
Sensor will display the Remote Room Sensor temperature.

NOTE: Smart Sensors must be addressed to identify which zone it will control. See
Smart Sensor Installation Instructions for details.

4.4. Wiring Considerations

Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal
wiring applications. Continuous wire lengths over 100 ft. should use 20 AWG or
larger.

8

NOTE: ABCD bus wiring 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.

Each communicating device in the Infinityr Zone System has a four --pin connector
labeled ABCD. It is recommended that the following color code be used when
wiring each device:

A — Green = Data A
B — Yellow = Data B
C — White = 24VAC (Com)
D — Red = 24VAC (Hot)

ABCD

A03193

It is not mandatory that the above color code be used, but each ABCD connector in
the system MUST be wired consistently.

NOTE: Some outdoor units provide their own low--voltage power source and do
not require the “C” (24VAC common) and “D” (24VAC power) connections. See
the outdoor unit installation instructions for more information.

9

ELECTRICAL OPERATION HAZARD

Failure to follow this warning could result in personal injury
or death.

Before installing, modifying, or servicing system, the main
electrical disconnect switch must be in the OFF position. There
may be more than 1 disconnect switch. Lock out and tag
switch with a suitable warning label.

!

WARNING

S Turn off all power to equipment.
S If an existing Infinityr Control or other control is being replaced:

d Remove existing control from wall.

d Disconnect wires from existing control.

d Discard or recycle old control.

S NOTE: Mercury is a hazardous waste, if existing control contains any

mercury, it MUST be disposed of properly. The Infinity Touch Control
does not contain mercury.

S Select Infinity Control mounting plastic (backplate and decorative backplate if

desired).

S Route wires through large hole in mounting plastic. Level rear plastic against

wall (for aesthetic value only; Infinity Touch Control need not be level to
operate properly) and mark wall through two mounting holes.

S Drill two 3/16--in (4.8 mm) mounting holes in wall where marked.
S Secure mounting plastic to wall using two screws and anchors provided.

10

S Adjust length and routing of each wire to reach each wire entry on the

connector backplate. Strip 1/4--in (6.4 mm) of insulation from each wire.

S Match and connect thermostat wires to proper terminals on control backplate.

d See wiring diagrams in Appendix A.

S Push any excess wire into the wall. Seal hole in wall to prevent any air leaks.

Leaks can affect operation.

S Attach Infinity Control to the mounting plastic by lining up the plastic guides

on the back of the control with the opening on the mounting plastic and push
on.

S Perform installation of all other system equipment (i.e. dampers, humidifier,

ventilator, UV lights, etc.).

S Turn on power to equipment.

4.4.1. Shielded Wire

If the thermostat wiring will be located near or in parallel with high voltage wiring,
radio, TV or Ethernet wiring, then four conductor, twisted--pair, shielded cable can
be used to reduce or eliminate potential interference. The shield wire should be
connected to the C terminal, or ground, at the indoor unit. The shield wire should
NOT be connected to any terminal at the user interface. Connecting the shield to
ground at both ends can cause current loops in the shield, reducing shield
effectiveness.

Connect one pair of the two--pair (minimum) cable to the A and B communication
terminals, and another pair to the C and D terminals at both ends of the cable. The
shield wire should ONLY be connected at the indoor equipment ground or C
terminal. Note that some outdoor units only require the A and B connections. See
the outdoor unit installation instructions for more information.

11

4.4.2. Damper Control Module (zoning systems only)

All wiring is run back to the Damper Control Module. Select a location near the
furnace or fan coil where wiring from the control, each Remote Room Sensor or
Smart Sensor, each damper actuator, and the equipment itself can come together
easily. The Damper Control Module is approved for indoor use only and should
never be installed with any of its components exposed to the elements. The Damper
Control Module (and zone dampers) may be installed in any area where the
temperature remains between --4_F to 158_F(--20_Cto70_C), and there is no
condensation. The cover must be installed to prevent damage from o ther 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.

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal injury.

To prevent possible damage to the Damper Control Module,
DO NOT mount on plenum, ductwork, or flush against
furnace or fan coil.

CAUTION

!

4.5. Mounting

First become familiar with all plastic assembly pieces shown on the following page.
The Infinity Touch Control will snap together with the backplate. A backplate is
supplied. Attach backplate using only a small hole in the wall allowing a four wire
connection to pass through. Mount the assembly to the backplate.

12

A12214

A12215

NOTE: Once Infinity 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.

4.5.1. Decorative Backplate

Sold separately, a thin decorative backplate is available to hide any marks/screw
holes left from the previous thermostat. This decorative backplate (or beauty ring)
is used by snapping it onto the back of the mounting plate before securing the plate
to the wall.

13

A12213

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
Infinityr System. The following is a typical example for a communicating
variable-- speed furnace / fan coil with a 2--stage air --conditioner / heat pump
(including HYBRIDHEATr dual 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”. This includes Infinityr small packaged
products (SPP), with UI Version 8.0 software or later.

A12177

NOTE: If the Infinity--compatible indoor equipment (furnace or fan coil) cannot be
found, the control will display “Indoor unit not found”. This MUST be 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 its DEMO operating 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”. This includes Infinityr small packaged
products (SPP), with UI Version 8.0 software or later.

NOTE: If the outdoor unit cannot be found, the control will display “Outdoor unit
not found”.

S Select the appropriate unit installed; then, touch NEXT.

d AC1Stage – 1-- stage air conditioner

d *AC2Stage – 2 --stage air conditioner

d *HP1Stage – 1 --stage heat pump

NOTE: For small p ackaged products (SPP), the selection screen is not needed and
will not appear.

S The installer will first be instructed to select the appropriate size of the outdoor

unit; then, touch SELECT.

*Network Interference Module (NIM) may be required for these selections to be displayed.

16

A13118

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, touch SELECT.

17

A13119

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.

18

A13117

5.5. Searching for SAM Module (If Applicable)

“Searching for SAM Module” will appear on the screen to determine if a System
Access Module, used for home automation only, is connected to the system.

NOTE: For more information regarding the SAM Module, reference the latest
version of the application specification entitled “Carrier Communicating HVAC
System” (Version 2 or later), available on HVACpartners.com, or the System
Access Module Installation Instructions.

5.6. 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, touch NEXT.

19

A12185

5.7. 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, touch NEXT.

S Air Filter: 1--in. to 4 --in. media filter
S EAC: high voltage electronic air cleaner
S Air Purifier: Infinityr or Performancet Air Purifier

5.8. Humidifier Installation

Next, the installer will be prompted to select whether a humidifier is installed in the
system. Select YES or NO, then touch NEXT.

5.9. Ultraviolet Lights Installation

Next, the installer will be prompted to select whether ultraviolet lights are installed
in the system. Select YES or NO, then touch NEXT.

5.10. 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

20

selected. If an incorrect selection was made, touch RE--INSTALL to restart the
installation process.

Example: SPP Equipment Summary Screen

A13120

5.11. 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
TrueSenset dirty filter detection operation will not be affected. When the static
pressure check is complete, touch NEXT.

NOTE: The static pressure check occurs only at initial installation, or when
INSTALL isrunintheINSTALL/SERVICE menu.

5.12. Duct Assessment (zoning applications only)

The duct assessment screen will be displayed n ext for zoning applications. Touch
NEXT to start Duct Assessment. Duct Assessment will measure the relative size of
the ductwork, up to and through the dampers. These measurements are u sed 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

21

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, touch NEXT.
