My Rheem Heatpump unit model #rpgb-025jaz had an old defrost circuit board that is start malfunctioning as a replacement,I bought new board model #47-21517-88,and unable to connect the wires of new board to the heatpump ,the new board did not have wiring diagram either. The old board has separate low ambent fan kit.& defrost relay. Please advise how to connect the new board to the unit.
