Fitting Honeywell CM927 Wireless stat.

Hi,

Just a quick question before I buy it.

I have an Potterton suprima 40 boiler with a Drayton RTS1 room thermostat.
I'd like to change it for the honeywell cm927.

I've looked at the wiring and it seems to be ok. At present I have live, neutral and call wires in the rts1. There is also an unused earth wire at the back of the box.
Looking at the wiring diagram for the cm927. As far as I can see, the Live would go to B, Neutral to N, Call to L.
This is for the burner (direct control) circuit diagram.

Does this seem OK?

Thanks.

Live = L
Neutral = N
Call = B
Link between L and A.
All as shown in the installation instructions.

Why are you replacing a wired stat with a wireless one?

No, it is live to left L, link right L to A and B is call. N is neutral.


FP beat me to it

Thanks guys.

Replacing as current stat is in hall where it is too cool. Only me in the house as well so I suppose it make sense to have the area where I am being at a comfy temp.
The programming aspects will also simplify things as well.
