1.Safety ConsiderationsImproper installation, adjustment, alteration, service, maintenance, or use can causeexplosion, fire, electrical shock, or other conditions which may cause death,personal injury or property damage. Consult a qualified installer, service agency oryour distributor or branch for information or assistance. The qualified installer oragency must use factory-- authorized kits or accessories when modifying this HVACsystem. Refer to the individual instructions packaged with the kits or accessorieswhen installing.Follow all safety codes. Wear safety glasses, protective clothing, and work gloves.Have a fire extinguisher available. Read these instructions thoroughly and followall warnings and cautions included in literature and attached to the unit. Consultlocal 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 CodeCSA C22.1.Recognize safety information. When you see this symbolon the unit and ininstructions or manuals, be alert to the potential for personal injury. Understand thesignal words DANGER, WARNING, and CAUTION. These words are used withthe safety-- alert symbol. DANGER identifies the most serious hazards, which willresult in severe personal injury or death. WARNING signifies hazards, which couldresult in personal injury or death. CAUTION is used to identify unsafe practices,which may result in minor personal injury or product and property damage. NOTEis used to highlight suggestions which will result in enhanced installation,reliability, or operation.1

2.IntroductionThe Infinityr System consists of several intelligent communicating componentswhich include the Infinityr Touch Control (or User Interface), variable speedfurnace or FE fan coil, 2-- stage AC and HP, (including Geothermal units),multi-- stage AC and HP, variable capacity HP and AC units, and Infinity SystemPackage units which continually communicate with each other via a four-- wireconnection called the ABCD bus. Commands, operating conditions, and other dataare passed continually between components over the ABCD bus. The result is anew level of comfort, versatility, and simplicity.All Infinityr System furnaces or fan coils are variable-- speed and multi stage formaximum flexibility, efficiency, and comfort. They support controlled ventilation,humidification, dehumidification, and air quality control. Either an Infinityr System(communicating), or a standard single-- stage 24VAC controlled outdoor unit may beused.When using conventional single-- stage outdoor units, the Infinity System furnace orfan coil provides the 24 volt signals needed to control them. When usingmulti-- stage conventional outdoor units or heat pumps, an Infinity SystemNetwork Interface Module or ”NIM” (P/N SYSTXCCNIM01) may be required toprovide additional control outputs. Also, the NIM allows connection of a CarrierHRV or ERV without the need for separate wall control.When using a Carrier HRV or ERV with a zoned system, the Infinityr SystemZone board allows connection of a Carrier HRV or ERV without the need forseparate wall control or NIM.All system components are controlled through the wall mounted Infinity TouchControl, which replaces the conventional thermostat and provides the homeownerwith a single wall control for all features of the system.2

4.3.Location!WARNINGELECTRICAL OPERATION HAZARDFailure to follow this warning could result in personal injuryor death.Disconnect power before routing control wiring.All wiring must comply with national, local, and state codes.4.3.1.Wall ControlThe Infinity Touch Control is the command center for the Infinity System. It shouldbe located where it is easily accessible and visible to the adult homeowner or enduser. For accurate temperature measurement, the following guidelines should befollowed: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 bemounted: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 othertemperature-- radiating objects which could cause a false reading.7

SSClose to or in direct airflow from supply registers.In areas with poor air circulation, such as behind a door or in an alcove.4.3.2.Remote Room SensorsA Remote Room Sensor can be used with the Infinity Touch Control to take theplace of the control’s internal temperature sensor. This allows the Infinity TouchControl to be mounted in areas with less than optimal airflow (such as near anexterior door, window or in a closet). The remote sensor can be wired to theterminal block connectors labeled S1 and S2 at the control’s backplate, or the ZS1and ZS1C connection at the Damper Control Module. In either case, the InfinityTouch Control will automatically detect the Remote Room Sensor and ignore itsinternal temperature sensor.NOTE: Humidity sensing will occur ONLY at the Infinity Touch Wall Control. TheRemote Room Sensor does NOT have humidity sensing capability.4.3.2.1.Remote Room Sensor AveragingTypically, one remote sensor is used but, multiple sensors may be used andaveraged in some applications. Averaging requires a special series-- parallel wiringmethod with a specific number of sensors. See figure below. It is also important tonote the humidity sensor cannot be remotely located, so do not locate the InfinityControl in an area where humidity sensing may not be accurate.8

Damper ControlModuleZSDamper ControlModuleZS CSensor 1Sensor 2Sensor 3Sensor 4A032334.3.3.Smart Sensors (for zoning applications)Any zone may use a Smart Zone Sensor (SYSTXCCSMS01). It provides atemperature display and buttons to adjust the desired temperature in that zone only.It also displays outdoor temperature and indoor humidity sensed at the Zone 1Infinity Touch control. Only one Smart Sensor may be used per zone. They cannotbe averaged like Remote Room Sensors. If a Smart Sensor is used in a zone, aRemote Room Sensor may also be used in the same zone. The Remote RoomSensor has priority over the Smart Sensor. The Smart Sensor will display theRemote Room Sensor temperature.NOTE: Smart Sensors must be addressed to identify which zone it will control. SeeSmart Sensor Installation Instructions for details.4.4.Wiring ConsiderationsOrdinary thermostat wire is recommended. Continuous wire lengths over 25 ft.should use 18 AWG wiring.9

NOTE: ABCD bus wiring only requires a four-- wire connection; however, it isgood practice to run thermostat cable having more than four wires in the event of adamaged or broken wire during installation.Each communicating device in the Infinityr Zone System has a four-- pin connectorlabeled ABCD. It is recommended that the following color code be used whenwiring each device:A — Green Data AB — Yellow Data BC — White 24VAC (Com)D — Red 24VAC (Hot)ABCDA03193It is not mandatory that the above color code be used, but each ABCD connector inthe system MUST be wired consistently.NOTE: Some outdoor units, typically those with multiple compressor stages,provide their own low-- voltage power source and do not require the “C” (24VACcommon) and “D” (24VAC power) connections. See the outdoor unit installationinstructions for more information.10

!WARNINGELECTRICAL OPERATION HAZARDFailure to follow this warning could result in personal injuryor death.Before installing, modifying, or servicing system, the mainelectrical disconnect switch must be in the OFF position. Theremay be more than 1 disconnect switch. Lock out and tagswitch with a suitable warning label.SSSSSTurn off all power to equipment.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.NOTE: Mercury is a hazardous waste, if existing control contains any mercury,it MUST be disposed of properly. The Infinity Touch Control does not containmercury.Select the appropriate Infinity Touch Control mounting configuration. Use thestandard backplate provided with the wall control, or add the decorativebackplate in addition to the standard backplate if desired. See Section 4.5 formore detail.Route wires through large hole in mounting plastic. Level rear plastic againstwall (for aesthetic value only; the Infinity Touch Control need not be level tooperate properly) and mark wall through two mounting holes.11

SSSSSSSSDrill 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 theconnector backplate. Strip 1/4-- in (6.4 mm) of insulation from each wire.Match and connect thermostat wires to proper terminals on control backplate.dSee wiring diagrams in Section 8.0.Push any excess wire into the wall. Seal hole in wall to prevent any air leaks.Leaks can affect operation.Attach Infinity Touch Control to the mounting plastic by lining up the plasticguides on the back of the control with the opening on the mounting plastic andpush on.Perform installation of all other system equipment (i.e. dampers, humidifier,ventilator, UV lights, etc.). See the equipment and device installationinstructions for details.Turn on power to equipment.4.4.1.Shielded WireIf 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 canbe used to reduce or eliminate potential interference. The shield wire should beconnected to the C terminal, or ground, at the indoor unit. The shield wire shouldNOT be connected to any terminal at the Infinity Touch wall control. Connectingthe shield to ground at both ends can cause current loops in the shield, reducingshield effectiveness.Connect one pair of the two-- pair (minimum) cable to the A and B communicationterminals, and another pair to the C and D terminals at both ends of the cable. Theshield wire should ONLY be connected at the indoor equipment ground or Cterminal. Note that some outdoor units only require the A and B connections. Seethe outdoor unit installation instructions for more information.12

4.4.2.Damper Control Module (zoning systems only)All wiring is run back to the Infinity System Damper Control Module(SYSTXCC4ZC01). Select a location near the furnace or fan coil where wiringfrom the control, each Remote Room Sensor or Smart (Zone) Sensor, each damperactuator, and the equipment itself can come together easily. The Damper ControlModule is approved for indoor use only and should never be installed with any ofits components exposed to the elements. The Damper Control Module (and zonedampers) may be installed in any area where the temperature remains between - 4 Fto 158 F (-- 20 C to 70 C), and there is no condensation. The cover must beinstalled to prevent damage from other sources. Do not locate where it will beaccessible to children. It may be mounted in either vertical or horizontal position.Remember that wiring access is likely the most important consideration.!CAUTIONPERSONAL INJURY HAZARDFailure to follow this
