How do I install the Carrier Infinity Thermostat?
Begin by turning off all power to the equipment and selecting your mounting type (recessed or surface mount). Route the thermostat wires through the mounting plastic, level it against the wall, and drill two 3/16-inch mounting holes. Strip 1/4 inch of insulation from each wire and match them to the proper terminals on the User Interface backplate according to the wiring diagram. Use 22 AWG wire or larger for normal applications, or 20 AWG for wire lengths over 100 feet. Finally, attach the Infinity Control to the mounting plastic by lining up the plastic guides and pushing it on, then turn on power to the equipment.
2
What are the correct wire colors for the ABCD connection on the Infinity Thermostat?
The recommended color code for ABCD connections is: A (Green) = Data A, B (Yellow) = Data B, C (White) = 24VAC Common, and D (Red) = 24VAC Hot. While it is not mandatory to use these colors, each ABCD connector in the system MUST be wired consistently throughout. If thermostat wiring is located near high voltage, cable TV, or Ethernet wiring, shielded thermostat wire can be used with the shield connected to ground at the indoor unit only, not at the user interface.
3
Where should I mount the Infinity Thermostat for accurate temperature readings?
The Infinity Control should be mounted approximately 5 feet from the floor on an inside partitioning wall in a frequently used room where it is easily accessible and visible. It should be on a section of wall without pipes or ductwork, and away from windows, outside walls, doors to the outside, direct light or heat sources, and direct airflow from supply registers. A Remote Room Sensor can be used if the Infinity Control cannot be mounted in an area with optimal airflow, allowing it to be placed in less ideal locations like near exterior doors or in closets.
4
How do I access the Install/Service menus on the Infinity Thermostat?
Press and hold the ADVANCED button for at least 10 seconds to enter the INSTALL/SERVICE menus. The menu will automatically exit after 60 minutes of no button activity. From this menu, you can access Equipment Summary, Install, Setup, Checkout, and Service options to view system information, add or change equipment, modify settings, test equipment operation, and view fault history.
5
What should I do if the Infinity Thermostat display says 'Indoor Unit Not Found'?
First, recheck the ABCD wiring on all devices to ensure all colors match for every terminal. Press the left-side button to try again. If the display still reads 'Indoor Unit Not Found,' disconnect accessories and all devices from the ABCD connection and connect the User Interface directly to the indoor unit with a short piece of thermostat wire. Add other devices one at a time to determine where the communication issue exists.
6
What is the correct procedure for initial power-up of a new Infinity Thermostat?
When power is first applied, the User Interface will display 'Establishing Communications With Equipment PLEASE WAIT,' followed by 'Searching For Equipment' and 'SEARCHING FOR OUTDOOR EQUIPMENT.' The system will automatically identify all Infinity components. You will then be asked to select the outdoor unit type (AC, HP, or None), enter the BTU size, select accessories (filter type, humidifier, UV lights), and review the Equipment Summary. After confirming all selections are correct, the system will perform a static pressure check, which takes about 1½ minutes to complete.

The Infinity System consists of several intelligent communicating components which includes the Infinity Control (or User Interface), variable speed furnace or FE fan coil, 2--stage AC or HP and Infinity Packaged Products, 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 Infinity 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 Infinity (communicating), or a standard 24VAC controlled outdoor unit may be used. When using conventional outdoor units, the Infinity furnace or fan coil provides the 24 volt signals needed to control them. Also, the Infinity Network Interface Module (P/N SYSTXCCNIM01) allows connection of a Carrier HRV or ERV without the need for a separate wall control. All system components are controlled through the wall mounted Infinity Control, which replaces the conventional thermostat and provides the homeowner with a single wall control for all features of the system.

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 Infinity System to simplify and automate the initial commissioning of the system. S Install Infinity 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.Installation
Check Equipment and Job Site Inspect equipment. File claim with shipping company prior to installation if shipment is damaged or incomplete. Infinity Control Location and Wiring ConsiderationsElectrical 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. Infinity Control Location The Infinity Control User Interface 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 Control and 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 Control and 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. 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. Remote Room Sensor Option A Remote Room Sensor can be used with the Infinity Control to take the place of the User Interface internal temperature sensor. This allows the Infinity 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 User Interface backplate, or the ZS1 and ZS1C connection at the Damper Control Module. In either case, the Infinity Control will automatically detect the Remote Room Sensor and ignore its internal temperature sensor. 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 Fig. 2. 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.

Fig. 2 -- Remote Room Sensor -- Parallel Wiring 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 Infinity 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) It is not mandatory that the above color code be used, but each ABCD connector in the system MUST be wired consistently. Shielded Wire If the thermostat wiring will be located near or in parallel with high voltage wiring, cable TV or Ethernet wiring, then shielded thermostat wire 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. Mounting Infinity Control First become familiar with all plastic assembly pieces shown in Figures 3 through 10. The User Interface will snap together with the backplate. A backplate is supplied (see Fig. 4 and 5). 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 (see Fig. 6 and 9) 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.Uid01--V

Electrical Operation Hazard
Failure to follow this caution may result in equipment damage or improper operation. Improper wiring of the ABCD connector will cause the Infinity System to operate improperly. Check to make sure all wiring is correct before proceeding with installation or turning on power.Caution
!Note:
For other applications not listed, refer to the Network Interface Module (NIM) Installation Instructions. Humidifier Connection 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 Control operate humidifier. Bypass Humidifiers A bypass humidifier should be wired directly to the furnace or fan coil HUM and 24VAC COM terminals. The Infinity Control 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 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.Equipment Hazard
Failure to follow this caution may result in equipment damage. Do not apply 24VAC fan powered humidifier (with internal power supply) direct to indoor unit HUM and COM terminals.Caution

Selects the airflow of the furnace when heating. EFFICIENCY is the airflow used to meet specified ratings, COMFORT is a decreased airflow used to increase the output air temperature and provide increased comfort. Cooling Airflow: S COMFORT (default) -- cooling airflow is varied depending on humidity and temperature demands settings. This selection enables the full dehumidify and comfort capabilities of the system. When COMFORT is not selected, the unit will not run reduced airflows for dehumidification. S EFF 325 -- fixed airflow used to achieve specified ratings -- no dehumidification airflow reduction. This is nominally 325 CFM/ton, but will vary if a 2--stage outdoor unit is used. S EFF 350 -- fixed airflow used to achieve specified ratings -- no dehumidification airflow reduction. This is nominally 350 CFM/ton, but will vary if a 2--stage outdoor unit is used. S MAXIMUM -- 400 CFM/ton. No dehumidification airflow reduction. S QUIET-- 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 be an issue. Heat Pump Heating: S COMFORT (default) Heat Pump airflow is varied depending on outdoor temperature to maximize comfort. S EFF 325 -- Fixed airflow used to achieve specified ratings . This is nominally 325 CFM/ton, but will vary if a 2--stage outdoor unit is used. S EFF 350 -- Fixed airflow used to achieve specified ratings . This is nominally 350 CFM/ton, but will vary if a 2--stage outdoor unit is used. S MAXIMUM -- 400 CFM/ton.

Operational Information
Continuous Fan Operation Pressing FAN button will scroll through the following: S AUTO = No fan operation except during equipment operation. S LOW = Approximately 50% of High Speed operation. S MED = Half way between High and Low speed operation. S HIGH = Highest of either High Heating or High Cooling CFM. Continuous fan operation is programmable. The programming option must be enabled in the Thermostat Setup. See the Homeowner’s Manual for detailed instructions on programming the fan. Five--Minute Compressor Timeguard This timer prevents compressor from starting unless it has been off for at least 5 minutes. It can be defeated by simultaneously pressing the Fan and Right Up buttons. Emergency Heat (for heat pump applications) To activate Emergency Heat, you must press and hold the HEAT button for 3 seconds to activate. Repeat to deactivate. Heat Source Selection (Hybrid or Hydronic Heat) If user wishes to override normal operation in Hybrid Heat or Hydronic Heat applications, press and hold the heat button for 3 seconds to select desired heat source. Keypad Lockout Keypad can be locked by pressing “Fan” and “Humidity/Oat” buttons at the same time for 3 seconds. When keys are locked, a lock symbol will appear in the upper left corner of screen. Follow same procedure to unlock keypad. Heat and Cool LED The Heat and Cool LEDs will pulsate during actual equipment operation. This can be defeated in the Advanced Setup Screens. Equipment Cycle Timer (adjustable 4--6 cycles per hour) This timer prevents the start of a heating or cooling cycle until 15 (or 10) minutes after the last start of the same cycle. Its function is to assure that the equipment is not cycled more than the selected times per hour. This timer is adjustable from 4 to 6 cycles per hour. This timer is defeated for one cycle when the desired temperature is manually changed. It can also be defeated for one cycle by simultaneously pressing the Fan and Right Up buttons. Staging Timer In multistage heating or cooling, this timer prevents any higher stage from turning on until the preceding stage has been on for 10 minutes. For furnace heating, the high stage timer is adjustable to force longer minimum low stage run time. See Furnace Setup for details. A demand of 5_ or more will override the staging timer and allow higher stages to energize. In Hybrid Heat, the staging timer is 15 minutes between heat pump and gas furnace operation. This timer is adjustable in the Hybrid Heat Setup menu to force longer minimum heat pump run time and longer low stage furnace run time. A demand of 5_F or more will override the staging timer and allow higher stages to energize. Three--Minute Minimum On Time In normal operation, when a stage turns on, it will remain on for a minimum of three minutes. If the setpoint is changed, this timer is automatically cancelled, allowing the equipment to turn off immediately when the demand is removed. Heat/Cool setpoints (Desired Temperatures) A minimum difference of 2_ (default) is enforced between heating and cooling desired temperatures. This is done by allowing one setting to “push” the other to maintain this difference. This difference is adjustable via the Install/Service menu under Thermostat Setup. Temperature Display The actual temperature displayed is always rounded toward the setpoint. This is because the system is operating and measuring the temperature in sixteenths of a degree, but displaying in whole numbers. The system may be turned off and on within .5_ of setpoint, but the display may not change. This is by design and does not indicate a problem with the control. Auto Changeover When Auto mode is enabled (factory default) a change from heat to cool (or vice versa) will not occur until an opposite mode demand has existed for 30 minutes. If the setpoint is changed, the 30--minute requirement is defeated. This Auto Changeover time is adjustable via the Install/Service menu under Thermostat Setup. Range = 5 -- 120 min. Smart Recovery With Smart Recovery selected (factory default), transition out of setback begins 1.5 hours before selected recovery time and gradually adjusts room temperature so desired temperature will be achieved at selected recovery time. It operates in both heating and cooling. This only applies to programmable operation. For example: Set back temperature in heating is 64_F. Smart Recovery setpoint is 70_F at 7:00 a.m. At 5:30 a.m., the control calculates the required temperature recovery rate (recovery temp -- set back temp or current temp if greater) / 90 minutes. If the current temp at 5:30 = 66_F, the recovery rate = (70 -- 66)_F/90 minutes = 0.04_ per minute. In order to achieve setpoint, the control ramps up the setpoint 0.04_F / minute from 5:30 a.m. until 7:00 a.m. This changing setpoint is displayed while it is occurring.Note:
Temperatures should not be set back so far that the equipment cannot recover in 90 minutes.Uid01--V

16 Air Filter If AIR FILTER or AIR PURIFIER is installed in the indoor unit, the system will perform a static pressure check of the system every 24 hours at 1:00 p.m. to monitor filter accumulation (TrueSenset Dirty Filter Detection) or whenever power is applied to the system or the system is transitioned from Off to Cool or Heat modes. The blower will run at a medium airflow for one minute. This system operates by setting a base line static pressure based on the highest airflow the system could run (this could be heat or cool airflow). The measurement is taken at a low airflow and then calculated up to the highest airflow the system could see. Frozen Coil Detection During cooling operation, the User Interface will monitor the static pressure of the system. If the static pressure is increasing dramatically, the User Interface will turn off cooling for up to one hour, record fault in the “Last 10 Events” screen, and run the fan at a reduced airflow. The User Interface will continue to monitor the static pressure. If it is reduced before one hour has elapsed, it will resume cooling operation. After one hour, cooling will be resumed. Dehumidify Operation Once a target cooling humidity setpoint is selected in the Advanced Setup COOLING HUMIDITY screen, two other setup options affect Dehumidify operation:
Cooling
Airflow
andDehumidify.
COOLING AIRFLOW: Setting this to COMFORT or QUIET will enable the system to use low airflow to help dehumidify the space. If duct sweating becomes an issue, setting DEHUM AIRFLOW to HIGH may resolve the problem. DEHUMIDIFY: Located in the Cooling Humidity screen of the Advanced Setup, this option has 2 settings: ON and OFF. If DEHUMIDIFY is set to ON (factory default), then the cooling unit will be allowed to overcool the space up to 3_F (2_C) if the humidity level is above the cooling humidity target setpoint. The amount of over--cooling allowed varies with the dehumidification demand, the cooling demand, and the actual space temperature. More over--cooling is allowed with greater dehumidification demand. When the space temperature is at or above 75_F (24_C) and the dehumidify demand is high, over--cooling up to 3_F (2_C) is allowed. As the space temperature approaches 70_F (21_C), less over--cooling is allowed. At 70_F (21_C) space temperature, no more over--cooling is allowed no matter how great the dehumidify demand. This is done to protect the equipment. If DEHUMIDIFY is set to OFF and Cooling Airflow is set to COMFORT, normal dehumidification mode is enabled. For normal dehumidification, no over--cooling is allowed when the cooling humidity is above the target setpoint, but airflow will be reduced during a normal cooling mode to reduce humidity. The airflow depends on the amount of dehumidify demand. If Cooling Airflow is set toEfficiency
orMaximum,
only Dehumidify (over--cooling to dehumidify) will be performed. Hybrid Heat Setup / Operation Furnace Lockout — (in HYBRID HEAT SETUP menu) is the outside temperature above which the furnace will not run except for defrost (otherwise known as the aux heat lockout). Heat Pump Lockout — (in HYBRID HEAT SETUP) is the outside temperature below which the heat pump will not run (otherwise known as the balance point). These values can be set identical to each other. If they are not identical, the system will stage up and down normally from heat pump to furnace when the outside temperature is between these settings. The User Interface will not allow the heat pump lockout setting to be above the furnace lockout setting. The factory default settings for both of these is NONE (no lockouts). Even though a heat pump lockout temperature may be set, the system will still use the furnace in defrost operation, and may stage back down to heat pump when defrost is completed after a 2 minute delay. Hybrid Heat Defrost — (in HYBRID HEAT SETUP) When the outdoor unit needs a defrost cycle, the furnace will run during defrost regardless of lockout temperature, unless told not to in the Hybrid Heat Setup screen. After defrost, the system may stage down to heat pump after a 2 minute delay. If the room temperature falls below 40_F (4_C) and a furnace lockout is in enabled, the furnace lockout will be overridden to bring on the furnace.Uid01--V
