[QUOTE="ProDave, post: 211122, member: 6969"] The timeswitch is in a convenient place in the house in the utility room. The boiler is in the garage, so not as convenient for access. Best leave it where it is, now Doc Hudson has shown us the easy way to rewire it leaving it where it is, and using the existing wiring. [SIZE=8px][COLOR=#C0C0C0]---------- Post Auto-Merged at 21:20 ---------- Previous post was made at 20:52 ----------[/COLOR][/SIZE] I should have spent more time making more notes. From L to R there's a power on indicator, a heating on indicator (and switch) and a hot water demand indicator, then a pressure guage. That may not be 100% but it's something like that. The live feed terminals were just two terminals, with one of those horrible "washer under a screw" earth terminals. Next to the mains in terminal block was a terminal block with 4 terminals. The middle 2 were bridged with a wire jumper. Removing the wire jumper turned off the heating, and with the jumper removed I measured 24V across them. While you might well be right, I didn't see any way to provide a switched live to activate the heating, just this contact switching some internal 24V circuit. Note to self. Before asking a question on the forum, write down the exact boiler model number first. [/QUOTE]
