Scanning Fault Messages - Viessmann Vitocrossal 100 Operating Instructions Manual

Scanning fault messages

If any faults have occurred in your heating system,
symbol " " flashes on the display and the fault code
is shown. The red fault indicator also flashes (see
page 10).
Example:
Fault code shown: "50"
1 5 0
Fig. 7
Danger
If faults are not rectified, they can have life
threatening consequences.
Do not acknowledge fault messages several
times in quick succession. If a fault occurs
repeatedly, notify your heating contractor so the
cause can be analysed and the fault rectified.
1. Inform your heating contractor of the fault code.
This enables the heating contractor to be better
prepared for the service call and may save addi-
tional travelling costs.
2. Acknowledge the fault message with OK. Symbol
" " no longer flashes.
Note
If you have connected signalling equipment to
■
indicate fault messages (e.g. a buzzer), this is
deactivated when the fault message is acknowl-
edged.
If the fault can only be fixed later, the fault mes-
■
sage will reappear the following day.
Calling up an acknowledged fault message
Hold down OK for approximately 4 seconds.
Note
If there are several fault messages, you can call these
up in sequence by pressing / .
