F40Outdoor discharge pipe temperature sensor abnormality

Name in the manufacturer's documentation (service manual): Outdoor discharge pipe temperature sensor abnormality[1]

In plain words (editorial)

The heat pump has detected a fault of the outdoor discharge pipe temperature sensor (its reading is used to detect a sensor error). The service manual names a faulty connector connection, the sensor itself or the outdoor 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.
