Introduction

The Infinityr® System consists of several intelligent communicating components which include 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 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 the 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.

Location

WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
Disconnect power before routing control wiring.

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

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:

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

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

• Close to a window, on an outside wall, or next to a door leading to the outside.
• Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature–radiating objects which could cause a false reading.
• Close to or in direct airflow from supply registers.
• In areas with poor air circulation, such as behind a door or in an alcove.

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.

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.

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.

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.

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)

WARNING

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing, modifying, or servicing the system, the main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch.  Lockout and tag switch with a suitable warning label.

• Turn off all power to equipment.
• If an existing Infinityr Control or other control is being replaced:
  • Remove existing control from wall.
  • Disconnect wires from existing control.
  • Discard or recycle old control.
    •  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.
• Select Infinity Control mounting plastic (backplate and decorative backplate if desired).
• 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.
• Drill two 3/16–in (4.8 mm) mounting holes in wall where marked.
• Secure mounting plastic to wall using two screws and anchors provided.
• 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.
• Match and connect thermostat wires to proper terminals on control backplate.
  • See wiring diagrams in Appendix A.
• Push any excess wire into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.
• 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.
• Perform installation of all other system equipment (i.e. dampers, humidifier, ventilator, UV lights, etc.).
• Turn on power to equipment.

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 the 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.

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° C to70° C), 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. It may be mounted in either vertical or horizontal position. Remember that wiring access is likely the most important consideration.

CAUTION
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.

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.

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.

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.

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.

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.

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.

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 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.

Commissioning

This section addresses initial power-up (or commissioning) of a new Infinity® 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 HYBRIDHEAT® dual fuel system).

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 an outdoor unit. If it is not corrected, the Infinity Touch  Control will go into its DEMO operating mode.

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”.

• Select the appropriate unit installed; then, touch NEXT.
  • AC1Stage – 1–stage air conditioner
  • *AC2Stage – 2–stage air conditioner
  • *HP1Stage – 1–stage heat pump
  • *HP2Stage – 2–stage heat pump
  • None – No outdoor unit installed

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

• 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.

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.

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.

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.

A13117

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.

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.

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.

• Air Filter: 1–in. to 4–in. media filter
• EAC: high voltage electronic air cleaner
• Air Purifier: Infinityr® or Performancet™ Air Purifier

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.

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.

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, touch REINSTALL to restart the
installation process.

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.

Duct Assessment (zoning applications only)

The duct assessment screen will be displayed next 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 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 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 backward), 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.

A12188

Airflow

This option allows the installer to select the appropriate airflow based on the needs of the installation. The QUIET airflow means the minimum cooling airflow that the system can safely run (typically 300 CFM/ton). Use this setting if duct noise is a severe problem. Note that duct sweating in high humidity environments could become an issue at low airflows. The COMFORT airflow means airflow is varied depending on humidity and temperature demand settings. This selection enables the full dehumidify and comfort capabilities of the system. The EFF325 airflow is a fixed airflow used to achieve specified ratings – no dehumidification airflow reduction is performed. This is nominally 325 CFM/ton, but will vary if a 2–stage outdoor unit is used. The EFF350 airflow is a fixed airflow used to achieve specified ratings – no dehumidification airflow reduction is performed. This is nominally 350 CFM/ton, but will vary if a 2–stage outdoor unit is used.  The MAX airflow is a fixed 400 CFM/ton. No dehumidification airflow reduction is performed.

The dehumidify airflow, when set to NORMAL, is allowed to adjust to a minimum to satisfy the dehumidification call. When set to HIGH, the minimum airflow during the dehumidify mode is increased to reduce duct and register to sweat. Also, the airflow increases minimum airflow during normal cooling operations to help reduce duct sweating.
After the selections are made, touch SAVE.
