I wish to connect a Honeywell CM67 programmable thermostat to a
Honeywell Sundial Plan Wiring Centre (S plan).

The sundial terminals for room stat are 1, E, 2, 3. The CM67 terminals
are N, L, L, A, B, C, D, E.

Which connects to which?

Many thanks for any advice given.

You can download the installation instructions from the Honeywell web site:

and this may help:

Live connects to A, neutral to B with my very similar CM900 which I have
just fitted.
