Dear All,

Requesting assistance on setting up the wiring between the Tado extension kit and a boiler that I have. Just working through the wiring; this is what my current setup looks like. NB: I do have an old thermostat installed (which is why I suspect Ls and LR are already in use).

I'd just like to confirm it is Ns, Ls, LR that I need to connect in the following manner:

Ns to -> N (blue wire) on Extension Kit

Ls to -> L (brown wire) on Extension Kit

LR to -> CH NO (grey wire) on Extension Kit

Then bridge on on Extension kit:

L to -> CH COM (purple wire)

Thanks in advance,

Ehsan

    In fact I think the answer is obvious on the actual instructions here on the bottom of the page; since I only saw LR on the diagram explicitly shown; I overlooked the blue and brown legend/table at the bottom:
