The Viessmann heating system operates almost unnoticed. It’s only noticed when problems occur and the room becomes cold. If a fault occurs with the Viessmann heating system, it displays a malfunction message. Below, we’ll explain the best course of action when this message appears and what to look out for.
What to do if a malfunction is reported
Basically, if something is wrong with your Viessmann heating system, it means there’s a problem with the heating system. This could be a defect or a malfunction. In any case, it shouldn’t be ignored. In the worst case, it could have serious and costly consequences.

How is the error message displayed?
