Hi, i have a honeywell timer for my central heating and hot water, it worked fine up until a couple days ago when i noticed that pressing the button for the hot water extra hour function, it wouldn't switch off after an hour, i would have to manually override it using the other button, the extra hour button works fine on the central heating
has anyone come across this before and is there a fix or will i need to replace the whole thing?
