UNIT OPERATION
This control board contains a five minute short cycle protector. A five minute delay will
occur between compressor off/on cycles. To bypass delay, short forced defrost pins
for 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 field
selected, dependent upon local georgraphic requirements. It is factory set at 90 minutes
and can be changed to either 30, 60 or 120 minutes.
Defrost - defrost will only be performed at outdoor temperatures less than 50ºF defrost
will 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 delay
20 Seconds before starting.
Field initiated forced defrost - (shown as forced defrost on board) by placing a jumper
across the forced defrost terminals for 5 seconds, or longer, and then removing the
jumper the unit will initate a defrost cycle regardless of coil temperature the defrost
cycle will terminate at 65ºF (+/-5º) if coil termperature is above 32ºF or outdoor ambient
temperature is above 50ºF, defrost mode will terminate after 30 seconds of active mode.

Short flashes indicate the first digit in the status code, followed by long flashes indicating the second digit of
the status code.
NOTES:
1. 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 D
terminals. Use factory provided wires to connect to R, C, W1, Y1, Y2, and O as required by
installation instructions. Cap or remove unused factory provided wires.
11. For communicating control only.
