Scanning fault messages
Note
■ If you have signalling equipment
(e.g. a buzzer) connected to the
Vitotronic control unit for the purpo-
ses of alerting you to a fault mes-
sage, the signalling will be stopped
when you acknowledge the fault
message.
■ If the fault cannot be rectified until a
later date, the fault message will be
displayed again the next day. The
signalling equipment will be
switched on again.
