Hi guys (and gals)
I hope you can help me. Will try to keep it fairly brief!
Have a Torrent ECO with woodburner downstairs, so gravity. All working well for the past year, apart from rads getting hot then cool (as the water gets pushed round the system) so instead of standing with my hand on the rad flow pipe to turn the heating off in order for the store to heat up again, I wanted a pipe stat to turn the pump on at temp (55 deg?). Also, I wanted the CH timeswitch moved downstairs.
Leccy man (a qualified friend in the area) duly moved Drayton Lifestyle downstairs (and immersion controls but that is separate and all fine), and wired in pipe stat. All seemed ok but tank not hot so not tested.
Later I had a bath using immersion and didn't want to waste a tankful of hot water so turned the heating from off to timed, and the fuse tripped.
Disconnected pipe stat and is not tripping anymore BUT the CH pump is now continually running (both valves are also vibrating) although the CH timeswitch is set to OFF.
I replaced the boiler overheat stat and still pump is ON.
So....
1. Can anyone see a glaring fault in my diagram (without pipe stat)?
2. Is this how it is supposed to be wired? (with pipe stat)?
Many thanks in advance.
