    Hi all I'm after some advice. My current alpha boiler has a wireless thermostat connected nothing fancy just one where you can set the on off time for heating etc etc. This has now broken due to me dropping it and the inlaws have give me a hive thermostat that they never had fitted to there boiler. I just wanted to check if I'm going about the right way of wiring it up I've added some pictures and hopefully I'm on the right tracks.

    So am I right in thinking i am to remove the wires from current wireless receiver and corresponding wires from the 230/240 supply block then

    Remove link then wire as follows
    boiler 1 goes to hive 1
    boiler 2 goes to hive 3
    boiler L goes to hive L
    boiler N goes to hive N
    boiler E goes go hive E
    Does number 34 on terminal x1 then go to number 1 on boiler? ( currently on number 3 on wireless thermostat)
    Hopefully I'm on the right lines but then again I could be miles off
    Many thanks
    Dave

    easiest way to do it, from the internal time clock pull off the 4 wires,

    brown to L on hive

    Blue to N on Hive

    two red wires to 1 & 3 on hive, doesnt matter which way around

    Thats it no earth, dont make any other links dont touch any other wires, clock wont work anymore as hive now controls the boiler

    Brilliant many thanks for that, never even give that a thought. Does it make a difference that its not an internal time clock but it's the alpha wireless receiver? If not is it OK to use spade connectors then tape over or better to solder and heat shrink? Will some 0.75m 4 core cable from screwfix be OK?
    Many thanks
