Hi,
Can someone please help me diagnose the following fault.
When my CH and HW both come on in the evening, my water and radiators heat up OK. However as soon the HW tank stat reaches temperature and stops demanding HW, my CH also stops. The CH will stay off regardless of the position of the room stat (which still clicks when turned pass the current room temp). If I increase the temperature of the tank stat, then the pump kicks in again and my HW and CH both start to work.
I think I have a Potterton boiler and programmer. This is a gravity fed non-combi system.
I'm thinking this could be the programmer that is faulty?
