Error messages
Device faults are sent to the central apartment unit as error messages and are
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.
If communication with the central
apartment unit is interrupted, the con-
nection and error symbols are dis-
played until communication is reestab-
lished.
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.
