Hello,
Apologies for anyone if this is a question that has been asked many times before, but I can't find anything that is exactly the same as mine.
I am attempting to install a Google Nest E to replace a Honeywell BDR91 for which the wiring is shown below:
I understand that as the Nest E has its own battery supply, then the N and L wires should be inserted into the terminating blocks. A and B in this case should be inserted into the C and NO, respectively.
However, the A wire above seems to be linked via the L terminal - does this mean that I should use the original L wire and insert that into the Nest C instead?
Many thanks for any help that anyone can provide.
