Scanning Fault Messages - Viessmann VITOTRONIC 300 Operating Instructions Manual

Scanning fault messages

Danger
If faults are not rectified, they can have life
threatening consequences.
Do not acknowledge fault messages several
times in quick succession. Notify your contractor
if a fault recurs. Your contractor will be able to
analyse the cause and rectify the fault.

Note
Fault messages from a Vitotronic 100 are not transfer-
