    So I'm waiting on my plumber to do the boiler and zones etc... we bought the hive in the christmas sale online... now im impatient to at least get some use out of it as it could be another few weeks before he can do the job.

    Our old boiler is obv still working etc... and is controlled by an old mechanical timer wiring which there is a pic of below...

    Now im an electrical noob but not COMPLETELY inept.. anyway I was going to put the receiver in myself for the moment so I could get some limited benefit from our hive..

    Behind the mechanical timer is 4 wires:

    The Hive Receiver calls for 5 wires (not including earth)

    So using the numbers i put on my own photo:

    1 - Live from mains
    2 - Live to Boiler
    3 - Common Link?
    4 - Neutral (easiest :p)

    Pairing them up to the Letters on the Hive wiring:


    N: Permanent Neutral = 4
    L: Permanent Live =1
    1: Common = 2 or 3?
    2: Heating off (NC): 2 or 3?
    3: Heating on (NO) = No clue?

    I have 4 wires and am looking to wire 5? Anyone help? I know I probably shouldnt do it myself but with mains off etc... as long as I know I wont fry anything... blah.


    Thanks for any help :)

    At a quick guess, you should be good with this (assuming you've identified the correct cables on your connection block):

    Your 1 (Perm Live) to Nest L (and Nest 1)
    Your 2 (Call for heat) to Nest 3 (NO)
    Your 4 (Neutral) to Nest N
    Nest L to Nest 1

    You should dig out that earth and connect it to the earth tether
