Honeywell R6660D to nest 3rd gen

[Stuart Norman]

Hi,

I am trying to work out how to map the wires from my honeywell wireless receiver R6660D to my new Hive receiver. Live/Neutral are obvious, but currently I have a green wire going into B and a grey wire into C, do these map directly across to the 2/3 connections on my new nest receiver?

Thanks for any help you can offer.
Stuart
