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:
 
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.
