I have an old Ideal Mexico 2 which just requires a live input to turn on. This once came from a timeclock but I replaced this with an Arduino and relay a while back. Wife not happy with any home built system hence need to instal the TADO (Starter Kit V3+).

Edit: Google tells me SL is switched live which sounds like the one I need, but in the wiring diagram it does not appear to connect to the controller, connecting only to O.

I’ll appreciate advice.

    I've figured it out. BR is the switched live that goes to the boiler. It's all working.
