I am talking about a Truma set up here. The dealer says that the valve is set for +3C. She gave me a document that says this clearly. However on the 2nd last page of it, there is this piece of kit. View attachment 279380The dealer has never fitted one but is on my behalf investigating the price and so on so I will up date as matters proceed However at the moment it seems to be the answer.

See my post on page one of this thread...may be of use ref frost protection
