strange one this.
I have a fully pumped system with two motorised valves, one for ch and one for hw...
Timer reaches set "off" time, hot water valve closes(i can hear and see it move) but pump continues to run. only way to stop it is to first manually turn the central heating on on the timer, then turn hot water off, then turn central heating off!! thought during cold weather it was the a frost stat in the boiler keeping the primary circuit flowing but it still does it now we have warmer weather!!
Timer problem or aux switch on the hw motorised valve??
