    Oh. I think we have all been looking at the wrong Nest diagram. Sorry.


    In that case L Brown to C and SL Green/Yellow to NO.

    N Blue in separate connector to make sure it doesn't touch anything else.

    As an electrician, now you don't need the Neutral any more, it would be better if, at the other end of the cable, you moved the Blue to where the Green/Yellow is and connected the G/Y to earth - then at the thermostat, swap the Blue with the G/Y...

    ... but maybe for another day.

    You appear to be living in the UK but the picture shows a USA version of the heatlink, which is completely different from the UK version.

    I followed the diagram tips from
    EFLImpudence and everything is working a charm.

    I am not sure wether my device is a US version - this is my first device and I claimed from the Shell deal when I switched to their energy services as my provider so that’s what they sent me.

    thank you all for the help. Without you I couldn’t have done it. Have a good one.

    Who is not paying attention? Nest e does not have line or neutral. So old A and B go to C and NO rest need terminating safely and are not used.
