Changing the head only? the valve could be tight or siezed usually better to change the unit. Anyway Geordie may be about soon he is the heating expert here :rockstar:

cheers but its only a few years old and heating did work when pulled the lever and locked the valve open

Brown is switched live from room thermostat, grey is permanent live and orange is switch live to boiler. CH on from programmer will be connected to the common of the room thermostat, thermostat calling for heat will then liven up the brown of the valve which will make it motor round closing the micro switch between grey (permanent live) and orange which is the switch live to the boiler.

seriously though look carefully at tels diagram, it clearly says ch and hw.

look where it goes from and to then look at your own and you will figure it out easy enough, ive been connecting valves today the main difference being mine were a bit bigger on a supply to a ahu

ive just googled and look through this it dumbs it down
