Hello guys here's a problem I am having and would appreciate any helpful advice thankyou.
i have a Honeywell Y plan heating system with three port zone valve and the heating and hot water stays on when the programmer is turned off.
i have renewed the programmer and the problem is still happening.
when I turn down the cylinder stat and wall stat this will turn off the pump and boiler.
So....I suspect the zone valve may be sticking but how does this explain a constant electrical signal going to the valve, only interrupted by the stats being turned off.
got me stumped as I have renewed the programmer and it's made no difference, any advice greatly appreciated thanks
