No did not drain the water down but I did have the hot water on @ the same time I tried turning all the radiators off. So thanks for that suggestion I will give it a go and then report back cheers
Hi all please help
I have just rewired the full system into a honywell sundial wiring centre after having loads of trouble with no hot water / no heating ect it was very temperamental. :twisted:
Now it’s rewired every thing is working ok i.e. the mid position valves the room thermostat...
