I have just moved into a house and the control seems to have a mind of its own. I have set the times for ch and hw to come on and go off, put the slider onto run and the other slider onto timed but the boiler does not respond to these settings. It comes on before my first setting time begins and I have to hit advance and turn the boiler on and off manually as required. The "copy " function is a complete mystery to me as I have no booklet on the control. Can you please help me?
