Dear All,
My first post and request for help. My daughter has recently bought her first house and we have been refurbishing for her. Having replaced all rads and valves we are ready for the CH/HW to go on, however we have a problem as follows:-
When the programmer is on CH & HW she gets CH and little HW but the boiler keeps cutting off on the overheat button. Having checked we have replaced the room stat for the same model so easy wiring. We also swapped the tank stat for ease and the mid point valve appears relatively new.
The mid point valve indicator (Drayton) shows C on the indicator when both CH and HW on the programmer.
When we have HW only on the programmer the valve moves to mid point but rads also get hot and remain so even of the room stat is turned down. The valve never appears to get to the H setting only. When HW is cut off by the tank stat the valve returns to C so tank stat obviously works.
Could it be the valve sticking or is there a wiring mess up between the programmer and valve
Many thanks
