Hi guys.
I've looked at loads of threads but I'm wondering how to install my nest 3rd gen.
I'm thinking I need to wire 4 wires?
Ns - N
LS - L
LR -3
And L to 3 ???
And also will I need to disable my programme box?
Thanks guys
Hi mate.
I'm wiring up my boiler..did u take a picture when you completed the fix. I know you took one before having the problem but never when it was working okay
