Hi all,
i'm trying to swap over a Randall SET2 with a SET2E but cant get it to come on.
My existing configuration below is how it was when I moved into the house, and I have a feeling its maybe not orthodox but thought these sets would be a like-for-like so would work:
Cable 1: Blue to N, Yellow to 1, Red to 5
Cable 2: Black to N, Red to L
Loop: L to 2 and 2 to 5
I've swapped the old terminal block with the new one. If I place the old box on it comes on and does what I expect but when I place the new box on nothing happens i.e. LED doesnt light, etc..
Im reluctant to follow the guide as im not 100% confident where the cables lead to on the boiler are where they should be...from what I gathered from previous posts.
Any ideas apart from the new box is faulty....?
