Error messages

Device faults are transmitted to the central apartment unit in the form
of error messages and are then displayed with the error symbol.
Device faults are communication breakdowns or short-circuits / open-
circuits of sensors in the room unit.
The error symbol disappears as soon as device errors are no longer
present.
In the event of communication errors, check the central
apartment unit's power supply. If power supply is in order, a
radio repeater might be required.
