Oh right cool, so I don't need 5 at all? It was only linking to N anyway?
So B's together and pushed into backbox
C's together and pushed into backbox
N to N
L to L
1, 3, 4 is 1, 3, 4 on new programmer
and remove link from 5 to L
Thanks!! :)
Right I'm modernising my Kitchen, I have an old grey boiler programmer that I'd like to swap to my new programmer.
My old Programmer is a Potterton EP2002
My new Programmer is a Honeywell ST9400C
I read on a forum that it is possible to change over, however I didn't realise so many wires...
