47-102684-204 Upgraded Heat Pump Control Board, Defrost Control Circuit Board Replace for Rheem 47-102684-14, 47-102684-07

The 47-102684-204 is a microprocessor-based demand defrost controller intended for 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.

• Before removing the old controller, note the location of the OCT sensor on the outdoor coil. The new sensor should be attached to the coil in the same location, or as close as possible. The OAT sensor is typically 24-48” long, although some controllers have the sensor on the board. Placement of the OAT sensor is not as critical as the OCT sensor, but both sensors are required for the controller to operate.
• Superior Quality, advanced microprocessor-based high-precision PCB manufacturing, soldering and assembly technology, professional tests to ensure optimal performance and long-lasting reliability.
• Note: to save yourself some hassle, please take a picture of the old one before removing it, make sure getting the wires on the correct terminals.Please feel free to contact us if you have any questions about our products, your satisfaction would be our greatest motivation.
