Hi Guys, just found this site and wonder if can help with a problem I have.
Please excuse my being vague about system manufacturers but this is an old system I installed and wired for my parents about 20 years ago as a solid fuel system. It was converted to a fully pumped gas fired system with a Gloworm boiler about 10 years ago. It uses a cyl stat, no room stat, 2 x 2 way valves and a 24hr 3 timezone programmer.
Right the system has performed faultlessly and correctly untill recently. The boiler then started to switch on and off at odd times throughout the day regardless of program setting, ie when set off on both hw and heating. The programmer was changed as it was the oldest part of the system and now switches both hw and ch correctly. However the hw proved to only funtion occaisionally. I then did what I should have done in the first place and checked the motor valve for the hw, it has gone. So motor removed and replacement on its way, (its the common type motor as used by honeywell although I think the valve was sold as wickes own label.
The system was wired conventionally and 2 the diagram in the boiler manual, although I cant explain exactly how its wired as it was 10 years ago and I don't have direct access to the system as I speak.
The boiler still switches on occaisionally even with the motor removed and the programer set to off.
Now the question is will this be down to the motor failure, as I'm assuming the aux swith is used to power the boiler, (can't remember exactly how it was wired, but if you lift the manual lever on either of the motor valves the boiler fires up.
Or is the whole top of the valve shot as I now suspect it maybe?
Or any other possibilities.
As I said sorry for the lack of info but I wont get back to this for a few days,
Cheers for any help offered
