White-Rodgers 47D40-801 Heat Pump Defrost Demand Control Board, Replacement for Rheem

The 47D40-801 control 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 to the heat pump system. The defrosting is performed by reversing the refrigerant direction of flow.

  • Direct OEM replacement
  • Heat pump demand defrost algorithm
  • Uses "self-calibrating" principles to calibrate itself
  • Replaces over 20 different Rheem applications
  • Includes Air and Coil Sensors
