13 fault diagnosis
In case the signal is lost between the room
thermostat and the radio receiver (e.g. : batteries
exhausted), the heating system uses its own
functioning settings.
Faults described in this chapter should be carried
out by a qualified engineer and if needed by the
After Sales Service.
You will find a list of certain error codes in the user manual.
