5.9 How to determine the fault problem of the HVAC thermostat?
Check the power supply: First make sure that the power supply of the thermostat is working properly. Check the
power switch and power connections to make sure they are securely connected together.

connections and use electrical insulation tape to keep them in place.
Check thermostat settings: Check the thermostat settings to make sure they are correct. Confirm that the set
temperature matches the actual temperature.
Check the HVAC/Heat Pump System: Finally, check that the HVAC/Heat Pump System is working properly, if not, it
could be the source of the problem.
If you are unable to resolve the fault, please contact a professional HVAC technician for further servicing and repair.
