I know there are several old threads on this topic but I would appreciate your advice.
Curently I have a 4360 f/stat wired T1 live/T3 neutral. I have a 641B pipe stat I want to connect up and I need to know exactly where I need to connect the feed from the pipestat to the f/stat.
Looking at the diagram T1 on the pipestat goes back to T3 on the f/stat, but where exactly does the feed from C on the pipestat go? Is it to the f/stat or the boiler wiring terminal block. If it is the latter it is a job for the professionals, not me.
TIA,
Colin
