I hope someone can help. Not had a hot shower since this started.
Away for a week when it was v v cold but to prevent freeze-related leaks the system auto switches on when the tank goes below a certain temperature so thought would be fine when I got back.
Rads work fine but if I switch on hot water the valve won't go to mid position as it should. If I switch off power to boiler it goes to hotwater only position, but I need a way to get it to do that with boiler operating! The manual control seems to have a mind of its own too, I am not convinced it works at all.
On top of that the auto protection is keeping the central heating going permanently at the moment so I can't test what happens from cold because it can't get cold!
Experts out there? or even someone that has fixed this before? Please!
