If the WaterFurnace Heat Pump control responds improperly, first ensure that the component being controlled (like the compressor, blower, or reversing valve) is functioning correctly. Next, verify the wiring from the control to the component is working properly, using the diagnostic outputs mode and LED Definition table. If these steps check out, consider replacing the unit control.
