    - Probable cause 1; Insufficient flow over the heat pump:
    - Possible cause 2; Blocked particle filter:
- 8.7 Information from the heat pump
  - 8.7.1 Heat pump is now working at its highest permitted temperature
    - Probable cause 1; The heat setting is set so high that the heating systems return temperature is too high:
    - Probable cause 2; The hot water temperature is set too high:
    - Probable cause 3; The under floor heating system or radiator valves are closed:
    - Probable cause 4; The flow across the heat pump is greater than the flow in the heating system:
  - 8.7.2 Add. heat is now working at its highest permitted temperature
    - Probable cause 1; The heat setting is set so high that the heating systems return temperature is too high:

    - Possible cause 1: The installer sets a high value for one of the above settings.
  - 8.7.4 Temporary stop of hot water production
    - Possible cause 1: Excessive temperature differential between evaporation and condensing. The compressor permits the additional heater to supply the correct temperature if it cannot do so on its own.
    - Possible cause 2: Low refrigerant level.
  - 8.7.5 Temporary stop of compressor operation
    - Possible cause 1: Outside temperature lower than -20 C.
    - Possible cause 2: Excessive temperature differential between evaporation and condensing. The compressor permits the additional heater to supply the correct temperature if it cannot do so on its own.
    - Possible cause 3: Low refrigerant level.
