Maintenance Tips
-
Protect from moisture & corrosion: Ensure the control panel housing is sealed—water intrusion is a leading cause of board failure in heat pump systems.
-
Check power supply stability: Verify proper voltage and breaker sizing to avoid electrical surges that can damage the PCB.
-
Inspect wiring connections regularly: Loose or corroded wires can cause faults, display issues, or intermittent operation.
-
Keep control compartment clean: Remove dust, insects, and debris that may short circuits or block airflow.
-
Monitor error codes & display behavior: Address faults early—this board manages key heater functions and diagnostics.
