    Hive installation on Potterton Promax HE Store

    Actually tested continuity and the 2 free wires are both connected somehow so maybe there is a loop. In the upstairs thermostat backing there was different configuration. It had grey, black and brown wire. I don't have the original set up but it seems the grey may be the odd one out and...

    Still no joy with this. Maybe it has something to do with the grey and black that are not connected. If I connect each like that pic above then will it work or will I blow something? The original wire seems like this: Brown -> Black Brown -> Grey The new wiring is: Brown *and* Black ->...

    So if I connect the brown and black wire together it will effectively make both live? Once live power goes to the CH area on boiler it tells boiler to activate? Maybe this switched live is missing then!

    How does switched live get its power? Is there something I can do that will make it live?

    No original wires to check which is live.

    With multimeter how do I test to confirm black and brown from original?

    Hive installation on Potterton Promax HE Store

    So am I correct in assuming if I restore the wiring as it was originally before the change over. Then the wiring for the zone valves and boiler will be correct. All that is then required is to trace original black (brown sleeved wire) and black wire from original thermostat and feed those into...

    Do you have a diagrammatic version of the answer? And also which wires correspond from old (original) eg Live in (is this black with brown sleeve or brown wire) = Common (or call) etc

    Can someone explain what the original thermostat black (brown sleeved) wire and brown wire represent? Where would these normally be connected? Do these go into the Hive terminal and if so which 2 points should this be? I have a suspicion the original thermostat actually controlled the on/off...

    I have no idea what this plumber did apart from take the money for installation! The only thing I have for comparison are the before and after pics of the terminal block. The connections to Hive plate are new anyhow it seems.

    Both wall plates have exact same wiring so didn't want tu duplicate on post. Both original thermostats also had the same coloured wires (brown cover on black wire). What do the wires from original thermostat relate to? Why is the black wrapped in brown tape? Is it to exemplify it is acting as...

    Yes. I have 2 single channel receivers. Sorry I assumed the photo of Hive backplate would have shown it was single channel. The old wiring with original wired thermostat worked fine. I assume the only thing that was required to switch to hive was disconnect the 2 wires from thermostat and feed...

    Lol does that make sense or am I over simplifying it?

    Hive installation on Potterton Promax HE Store

    I think the only thing I need to do is rewire as it was originally but then feed the 2 wires from wired thermostat to Hive and supply power to hive. Every other change seems unnecessary?
