LS LR on your boiler pcb is a low volt / no volt jumper connection. You actually pointed that out in the second paragraph of your initial posting.

Control valve micro switches should be wired low volt / no volt too.

As I said im going back tomorrow night to check for continuity and identify all my cables again.

Interesting comment ........ I had read this as it was your own home, but are you doing this for a paying customer?

Are you a spark or GSR?

Just because he says Ls is low voltage doesn’t mean it is. As you are talking about LS and LR and clearly don’t know what you are talking about he needs to get a GSR in to remove the boiler cover and correct the wiring which is clearly wrong by the sounds of it.

Im a spark doing it for my uncle. Its a void guest house. Ls from boiler is 240v..and Lr is a 240v switched live. Im going to sort it tonight. Ill let you know what the f**ck up was. Thought id have a bit more sense from the forum. But it was obviously a bad idea coming here to be pointed in the right direction.

I have posted the best sense that I can give you above. Put the case back on the boiler and get a GSR out. Either your wiring is wrong or the boiler is at fault. Either way get a pro out.
