Installing Wireless Honeywell CM927 Thermostat

[Lizardlips]

Hi

I have a Worcester CDI 30 Boiler, and want to fit a Honeywell CM927 wireless thermostat to it. Any advice would be appreciated regarding wiring.

At the boiler, I have terminals NS, LS, and LR.

At the BDR91 reciever I have N, L, L and A, B, C.

I am pressuming that LS is wired to A, and LR is wired to B.

Not sure about the NS.

Any explanation or advice on this would be appreciacted. Thanks everyone.

Ns doesnt go anywhere.
no need for it
L and neutral for reciever comes from fused spur

Thanks.

So am I right in thinking.

Live and neutral from boiler fused spur to L and N in the reciever. And then just LS and LR from the boiler to A and B in the reciever?

Thanks again
