Before requesting service, please check whether:

• the heating system is properly pressurized and correctly vented
  (the system should be filled to the value specified by your heating technician – usually around 1.5 bar),
• the circuit breakers for the heat pump are in the “on” position
  (the breaker lever in the on position should be in the upper position. On the other hand, switch off the heat pump at the breaker if there is a risk of damage to health or property. Do not switch off the heat pump during the defrosting phase of the outdoor unit to avoid damage to the heat exchanger),
• the heating system filter is properly cleaned
  (before cleaning, do not forget to switch off the heat pump using the user controls),
• all valves on the pipes through which water flows are in the open position
  (the lever of ball valves is usually open if it is parallel to the pipe),
• there is no water leakage from the heating system,
• the temperature sensor of the storage tank has not fallen out of the sleeve,
• the airflow through the outdoor unit is not blocked (e.g. by fallen leaves, etc.) and the condensate drain from the outdoor unit is not clogged.

If you have problems with internet communication, first restart the router and check that the ethernet cable is properly connected. For a non-communicating WiFi sensor, first replace the batteries and reconnect it to your WiFi network.
