[QUOTE="lilman, post: 290682, member: 793"] Quick update - visited premises again today. Heating engineer changed valve for another Honeywell 3 way. Same problem. All connections to boiler removed. Cylinder stat removed. No room stat. Hot water on 230V at sw live out. Hot water off 0V at sw live. Heating on 230V. Heating off 109V. Did notice that the valve seems to stop momentarlly at 109V on the way to 230V when the heating is switched. I'm stumped. Definately not the boiler. Wiring centre is all good. Tried replacement programmer. Only thing it could be is a duff batch of Honeywell valves? Engineer is gonna try it with a Drayton valve. I'll let you know the outcome. [/QUOTE]
