Hello all,

Ok, in principal, it seemed like a job i could do, but looking at the wiring
diagram, it confused, at least I think Iam.

I have a Worcester Bosch Highflow 400 combi and a Honeywell RM67RF room
stat.

The wiring diagram for the combi, shows a connector for a room stat, with a
live, a switched live, and a neutral.

The stat needs a 230V 50/60hz live and neutral, which according to the
diagram then continue onto the live and neutral to the combi. It also needs
a connection from the combi (it calls the terminal T1) to terminal "A" on
the stat and one from T2 on the combi to "B" on the stat. This is labelled
as 24-230V 50/60Hz, A-B 10(3)A and A-C 5(3)A (there is also a C D and E
terminal on the stat, the B and C seem to be the switch to call for heat.)

I'm just not confident to have a go, and want to get it right in my head
before I try it. Has anyone got any ideas??

Actually, thinking about it now, do I take the switched live on the boiler
to the stat terminal A and the Live on the boiler to the live on the stat
(so the switched live would be T1). That just leaves a neutral and a T2 to
look after!?

Cheers
Mike
