Depending on the model of boiler, you could access the electrics?How do I no what one is switch live back to boiler?
Im trying to account for an extra wire in terminal 8.What do you mean by separate system pump?
Ok, try orange into 8.There’s a central heating pump
If you can run hot water by itself, it suggests to me it’s been wired unconventionally, as you can see hot water alone should be the orange wire. So you’re looking possibly for the room stat live in, which could be terminal 4. Could always try the orange wire in that anyway I’d you be already tried it in a different oneOrange into 8 didn’t work! Still have to run the hot water and hearing together to get the heating to work! I can run the hot water by itself
