Rheem 47-102738-154 Model Data Memory Card Heat Pump RP20

Product Description

The RHEEM 47-102738-154 is a model data memory card (EEPROM) designed for use in heat pump systems. This card stores unit-specific configuration and operating parameters that the control board reads during startup and operation. It is a direct OEM-style replacement component installed by licensed HVAC technicians during diagnostic service, control board replacement, or unit commissioning. The card measures 5.3 inches in length, 3.1 inches in width, and 2.0 inches in height, and weighs 0.2 pounds. Proper model data must be present for the heat pump to operate within designed parameters.

This memory card is used on the RHEEM RP20 heat pump model line. It is typically encountered during field service when a control board is replaced and the unit-specific data must be transferred or restored, or when the original card has been damaged or lost. Installation is performed by a qualified HVAC service technician familiar with RHEEM heat pump control systems.
