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.
