Based on what you have said so far, it could be the room stat not working, or perhaps a valve not moving correctly.

I think the problem might be the programmer not communicating to the boiler or a fault in the micro switch in the boiler will check it out tomorrow thanks Tony -- |

Find a wiring diagram for the valve and a multimeter, Agreed. Either the micro-switch has failed, or the valve is opening - but not far enough to operate the micro-switch. -- Cheers, Roger ____________ Please reply to Newsgroup.

Find a wiring diagram for the valve and a multimeter, Hi Bob yes your right i found that the micro switch on the ch valve was at fault ive changed it over and all is working well now. How do you mean, changed it over - swapped in a new one? How did you do that? It looks easier said than done on a Honeywell 3-way motorised valve. -- Les |
