Hi, Looking at the manual, I think I have an S plan heating/hot water system.
1. When only the hot water turns on (central heating off, on the programmer/controller), the pump and two Honeywell V4043 valves open and the central heating comes on too. Is this normal for an S plan system?
2. Also, recently, even when the central heating thermostat in the lounge is turned up (flame icon is showing so boiler should be on) the boiler is not kicking in, nor the pump or valves. Is this is a problem with the lounge thermostat or maybe something else? Can I test the stat somehow or is it defo dead - multimeter?
Any help appreciated. I'm moving house in a week's time, and don't want to leave the new people with a problem as Winter kicks in
