Hi
I apologise in advance if this post seems a little vague, I am posting on behalf of a friend.
He has a boiler and a heating system which is controlled by a silver box with a dial (timer) this controls the heating and also controls the hot water , the hot water still works but the central heating no longer works, on this type of system (again apologies if this is vague) is each system controlled by a switch or a FCU , he has sent me a pic of the timer box and there appear to be 2 switches around the box but they aren't FCU's
Pls can you advise what the most likely fault this could be just to give him an idea of what sort of fault he is looking at
Thank you
Stephen
