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 75ºC (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.
9.   In case of a communicating indoor system, 

 USE WITH INFINITY / EVOLUTION USER 

      INTERFACE AS LISTED IN PRE-SALE LITERATURE

.

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 Y1, R, C, and Y2 as required by
      Installation Instructions.  Cap or remove unused factory provided wires.
11.  For Communicating Control only.

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.
