Hi all.
It was working fine and then suddenly stopped working. Radiators not working but hot water is. Workmen were working at the house to repair a leaky roof and I found the property's fuse box cabinet open, so I am not sure if it could be the workmen that broke it or if it could possibly be water damage. I am not sure how to tell which exact model it is but it looks like the one in the picture below.
The display is completely blank. I have tried new batteries but that hasn't made any difference. I have read that if it needs replacing, it needs to be replaced by the same item as it needs to match with something in the boiler (Vaillant ecoTEC plus). Is this true?
Are there a million things that could have gone wrong with it or can anyone suggest the most common likely issues?
Thanks.
