    Hello, please can someone help me?

    Pump connection (LR) switch live terminal - What does this need to be connected to, in the wiring centre junction box, please?

    Any guidance would be very much appreciated

    Kind regards :D

    Thank you for your quick response

    The diagram I have for the third party control unit only shows Pump L & N, with L connecting to Orange / Valve, so if I join the LR to Orange / Valve, do I connect Pump L to Direct Live?

    TIA :D

    tbh if ya asking this ya should get someone in to sort it. but if ya want to have a go...
    permanent mains supply to ya l on st1
    pump needs to be wired to the boiler on st2 (Lp being the live)
    the orange from the wiring centre needs to be wired to Lr (also on st2)
