    Hi

    I am replacing a Danfoss RX1 wireless stat receiver with a Hive V2. My system has the following components

    Honeywell Programmer near the boiler
    RX1 near the wiring center
    Honeywell Wiring Center

    The backplate of the programmer looks compatible with the Hive receiver so just planning to swap that out as the wiring diagrams for both are the same.

    My question is concerning what to do the with the RX1 stat receiver. It's connected into my wiring center as pictured. Is it ok to just remove this or do I need to link any of the pins?

    Configured our side and provide to BT

    The room thermostat terminals will be marked from the top to bottom as follows.

    1. (Live)
    E. (Earth)
    2. (Neutral)
    3. (Switched Live)

    These are marked for Honeywell T6160 thermostats which use terminals 1 & 3 for switching. So, remove all four wires, and the cable that goes to the thermostat, and then inset a link between terminals 1 & 3

    Thanks for this. Because it's a danfoss wireless receiver these four wires are the only ones present. The stat in the hallway is wireless and connects to it. I had a feeling just removing the four wires wouldn't be enough. I will put a link wire between 1 & 3 then.

    Thank for guiding me

    A wired thermostat, and a wireless receiver perform exactly the same switching functions and use the same connections. The wiring centre doesn't know what's connected to it, so that's fine.

    Hi just gone to do this but noticed that there is also a single wire going from the stat receiver to the heating valve.

    I could disconnect it but assume I need to provide power to it.

    Can anyone advise?

    To clarify it's the brown cable on the Honeywell wiring centre labelled grey on the HTG section.

    So if I understand correctly, you are saying, that in addition to the four wires going from the wiring centre to the roomstat receiver (black, yellow, blue, grey) There is also a single brown wire from the receiver going to the wiring centre terminals marked 'heating valve grey'? (and not the actual "heating valve" itself)

    If so, can you post back details of the thermostat receiver wiring and where each of the 5 wires are connected?

    Just disconnect that brown, it is connected to that terminal marked grey as it is a permanent live to keep the receivers electronics powered all the time. putting the brown there is easier than trying to fit it in with another wire.
