Wiring Diagram25HNB9Infinityr 19 2---Stage Heat Pumpwith Puronr Refrigerant2 to 5 Nominal Tons338865-101 REV. A1. Compressor furnished with inherent thermal protection.2. To be wired in accordance with National Electric Code (N.E.C.) and local codes.3. Outdoor unit control requires a minimum of 27 va, 24 vac control power.4. Use copper conductors only. Use conductors suitable for at least 70ºC (167ºF).5. If indoor section has a transformer with a grounded secondary, connect the grounded side to “C”.6. If any of the original wire, as supplied, must be replaced, use the same or equivalent wire.7. Check all electrical connections inside control box for tightness.8. Do not attempt to operate unit until service valves have been opened (Back Seated).9. MUST USE THERMOSTAT OR USER INTERFACE LISTED IN PRE-SALE LITERATURE ONLY.10. In case of non-communicating indoor system disconnect factory provided wires from A, B, C, and Dterminals. Use factory provided wires to connect to R, C, W1, Y1, Y2, and O as required byinstallation instructions. Cap or remove unused factory provided wires.11.

A five minute delay willoccur between compressor off/on cycles. To bypass delay, short forced defrost pinsfor 1 second then release. The crankcase heater is energized during off cycle below 65ºF.Defrost time selection - (shown as DT on board) the defrost interval time can be fieldselected, dependent upon local georgraphic requirements. It is factory set at 90 minutesand can be changed to either 30, 60 or 120 minutes.Defrost - defrost will only be performed at outdoor temperatures less than 50ºF defrostwill initiate when time selected has elapsed and the coil temperature is less than 32ºF(+/-2º) And will terminate at 65ºF (+/-5º) upon defrost termination the outdoor fan will delay20 Seconds before starting.BLUYELBLKFLASHCODE FAULT DEFINITION FLASHCODE FAULT DEFINITIONOn, No Flash Standby1, Pause Low Stage2, Pause High Stage1625 Invalid Model Plug31 High Pressure Switch Trip orDisch Temp Switch Trip45 Control Fault46 Brown out (230V)47 No 230v with call to run53 Outdoor Air Temp Sensor72 High Stage Thermal Cutout73 Contactor ShortedSystem Communications Failure32 Low Pressure Switch Trip71 Low Stage Thermal Cutout74 Contactor Open (No 230v to Comp)55 Coil Temp Sensor56 Temp Sensor Range Error81 Low Stage thermal lockout (4 HRS)82 High Stage thermal lockout (4 HRS)83 Low pressure lockout (4 HRS)84 High pressure lockout (4 HRS)Short flashes indicate the first digit in the status code, followed by long flashes indicating the second digit ofthe status code.3, Pause ODU Fan Delay Defeat Not Active4, Pause5, Pause6, PauseODU Fan Delay Defeat ActiveBrown Out is DisabledBrown Out is ActiveOPTIONALNON-COMMUNICATINGCONTROLSEE NOTE #10R C W1 Y1 Y2 OAS PROVIDEDBY MANUFACTURERSEE NOTE #11A B C DGRNYELWHTREDPL7 R C Y1W1 Y2 OAS PROVIDEDBY MANUFACTURERSEE NOTE #11A B C DGRNYELWHTREDOPTIONALNON-COMMUNICATINGCONTROLSEE NOTE #10R C W1 Y1 Y2 O024 10 5.1 120Fig. 1 – Wiring Diagram — Model sizes 2 -- 5 tons, 208/230--1 |
