when the control is swithced to c/h & hot water my central heating comes on automatically (although the slider is set to off)
if the control is set to hot water only my central heating still comes on
it does not matter whether the central heating slider is set to on, off or timed is still comes on automatically.
..basically mycentral heating runs 24/7 (unless i turn the boiler off via the plug or boiler control)
what can the problem be?
i have replaced the diaphragm and gas valve in the past 12 months to solve other problems i had.
any help would be much appreciated.
thanks
