Connecting Netatmo Smart Thermostat to Honeywell Home V4043H zone valve

netatmo

We have set up our new boiler which is using 3 zone valves for different areas of the house.  We are using Honeywell Home V4043H zone valves and need to connect each to a Netatmo Smart thermostat.  Can anyone help with which wires need to connect to which?

    I found the following wiring diagram for the V4043H zone valve:

    Green/Yellow = Earth
    Blue = Neutral
    Brown = Live to Motor
    Grey = Permanent live to switch
    Orange = Switch live output from switch

     


    Therefore you must connect the Valves Brown and Blue wires (and Green/Yellow) to a power source, as well as the brown and blue wires of the Netatmo Relais. Then you have to connect the orange and grey wires of the Valve to the black and grey wires of the Relais. Polarity doesn‘t matter in that case.

    This way the Netatmo Relais should be able to open the V4043H zone valve.
