Before programming, understand what you are looking at:
If the parameter matrix becomes corrupted or unmanageable, you can restore factory defaults: Power down the controller. Power up the unit while holding down the key.
: To enter the full menu, press and hold the SET button for more than five seconds until "PA2" appears.
Determines fan behavior during compressor operation. 0 = fans run continuously; 1 = fans cycle on/off with the compressor.
