    Hi there,

    I'm trying to figure out the wiring from old timer controller to my new Hive Thermostat.

    I've an ideal logic heat H18 boiler which has an old timer controller with 4 wires, diagram looks like this:
    old_diagram.jpg

    And in real life this looks like this:
    old_wires.jpg

    The Hive Wiring diagram seems to be looking for 5 wires:
    hive_wiring.jpg

    Old N and L will transfer directly to Hive N and L.
    If I transfer
    old 1:black -> Hives 1:Common
    old 2:brown -> Hive's 3: Heating on

    Is that sufficient? (Do I need Heating off?).

    Cheers,

    Olsiron

    oh... good point. I probably didn't think that through.

    So yep the boiler supplies heating and hot water. I guess I should be looking at dual channel?

    So in that case, should it be:
    old:1 -> Hive's 3: Hot Water on
    old:2 -> Hive's 4: Heating on

    Does 1:Hot Water off and 2:Heating off need to be linked up (to Neutral?)

    Cheers,

    Olsiron

    Yes to live and neutral also 1 and 2 to hives 3 and 4 but I have no way of knowing which is which, you don't need any other connections.

    The old controller had a diagram which indicated the correct wire for Hot Water and Heating. All wired up and working! Thanks for your help picasso!
