I currently dont have a room stat and am considering one of these.

I have a Y-plan system, all honeywell - my question is, does it wire into the wiring centre or direct to the boiler? I can't find a wiring diagram for it.

I was considering replacing the programmer but this one is cheaper.

Thanks
Mike

Wires into the wiring center, and you still need the programmer

OK cool thanks.

Don't suppose you can point me in the direction of the wiring diagram please

Within the wiring junction box, there is a jumper between two connectors.. im guessing it goes here but obviously would need to check that.

Cheers

EDIT: I have a junction box not a wiring centre... ooops

There's a wiring diagram on the download from that page.
