Good morning,
I have a 3 year old Sauner Duval Xeon Condens 18 which for the last 5 mornings the overheat stat has tripped causing me endless pain on my ears from the Mrs for not having heating/hot water. After resetting the stat it works fine again for about half an hour then trips again. I have made sure all the rads are bled and getting hot, also when it works the water is hot. Fault code F5 is shown on the lcd display =overheat fault. The pump is working. Could this be something as simple as a faulty stat or does this need to be looked at in more depth.
Thanks
