    Hi all, I'm looking to replace my current Honeywell thermostat with a Nest learning thermostat. In terms of installing the Google heat link will I be able to swap these over like for like, or will I need an additional wire/s from boiler to the nest heat link? I've included a picture of the current thermostat receiver.
    Thanks for your help in advance

    That's a straight swap. Line to Line, Neutral to Neutral, A to 2 and B to 3. Do not install any link wires
