Air Handler
NNootteess::
• Install supply fan run out, (UC) J18-1, and ground (UC) J18-2 to air handler.
• Power (24VAC) and ground from the condenser are required for Evaporator Defrost Control (EDC) signal.
If the EDC switch in the air handler will be utilized for low evaporator compressor protection, the
Symbio Service and Installation Mobile Application can be used to edit the (EDC) for direct or
reverse logic. Go to Tools > Service > Customer Connection Polarity, and change the Demand
Limit Input to DDiirreecctt or RReevveerrsseedd.
