I have sorted it out now, very quick response from them. I did email ages ago but no reply. Not really had a need to be on the combustion chamber but....
I have a potterton suprima standard efficiency that keeps locking out. It runs fine when I am there, but they say they re set it 3 times a day. I have changed the o/h stat and temp sensor. Literally everything checks out fine and the flow return temps are good and the difference is about 10. Apart from suggesting a board then I am stuck. It looks like it has one of the new boards on it. Any ideas dan?
