Hi,
We have above bioiler. Runs through programme then at end of programme boiler stat seems to go mad - constantly clicking ( think it's the stat - noise coming from that area ). Also the pump keeps running, not just to cool the system but runs for hours till next programme. If I shut boiler down & back on, clicking & pump still going till next programme. Programme seems to run OK.
any ideas
