1. How does a thermostat affect heat pump operation?

  • Temperature settings: The airflow, temperature of the room, air quality; everything depends on the thermostat. When the temperature settings on the thermostat are not accurate and according to your comfort level, you can feel an error in room temperature.

    Your heat pump will partially heat or cool the room or completely stop heating and cooling. In this case, you will have to reset the thermostat settings, but if you find that your thermostat is not working at all, it may need new batteries.

  • Incorrect calibration: You also have to ensure that your heat pump is accurately set to the cooling or heating mode and you have set its fan to auto mode. If your heat pump is not reading the correct temperature even after resetting the temperature and replacing the batteries, it can be due to incorrect calibration.

    You can recalibrate your heat pump through its manual guidance, and if you find this hard, you can contact a professional.
  • Power supply issues: The location where the thermostat got installed also matters in its performance. A thermostat in an area where direct sunlight reaches will not read the accurate temperature. A thermostat not receiving enough power supply also malfunctions and stops a heat pump. You will need to check the wiring and fix it to solve the problem.
