Hi, my radiators are getting hot when only the hw is selected on the boiler. I have recently replaced the 3 valve actuator (sunvic 2701) which has brought down the tap water from 20,000 degrees but now i have this new problem. is it possible that i have fitted it incorrectly i.e. does the valve need to be in the correct position when i put it on? sorry if this question has been answered before.
