F45Indoor water outlet temperature sensor abnormality

Name in the manufacturer's documentation (service manual): Indoor water outlet temperature sensor abnormality[1]

In plain words (editorial)

The heat pump has detected a fault of the indoor water outlet temperature sensor (its reading is used to detect a sensor error). The service manual names a faulty connector connection, the sensor itself or the indoor unit PCB as causes.

When to call a service technician: Contact the installer or Panasonic service – the sensor, its connector and the PCB are checked inside the unit.
