White-Rodgers 47D43-811 Heat Pump Defrost Demand Control Board,

White-Rodgers 47D43-811 Heat Pump Defrost Demand Control Board, Replacement for Rheem
The 47D43-811 is a microprocessor-based demand defrost controller intended for Rheem heat pump systems. This controller uses basic differential temperature means to detect degradation of system performance due to ice build-up on the outdoor coil. The controller uses “self-calibrating” principles to calibrate itself to the heat pump system. The defrosting is performed by reversing the direction of flow of refrigerant.
