I finally got round to order the Horstman Centaurstat7 when my wife said we should stick with a Honeywell as we can't find any reviews of the Horstman Centaurstat7 so here I am again asking the following question:

Bearing in mind that I already have a Honeywell T6360 and a (sealed) CH system. How would I wire up this CM907 7 days programmable thermostat http://www.honeywelluk.com/products/Programmable-Thermostats/Wired-Programmable-Thermostats/CM907-7-Day-Programmable-Thermostat/

Thanks in advance for your help.

Thanks espresso, you are very helpful indeed.

Well, thanks to TonyMMM I managed to find some reviews and he also convinced me to go for the Horstmann unit which I purchased today.

Looking at the connection instruction and trying to figure out the instructions you gave me a while ago fits in all this.

It seems this unit can be wired for different CH systems. I have sealed system (boiler + pressure cylinder) but it's not a combination boiler. There is also a programmable unit that controls the CH and HW.

I'm yet to remove the old thermostat so I don't know how many wires I will find but assuming from your information there will be 3 wires.

Can you confirm that with the information I have just provided the wiring instructions you originally gave me are still valid.

Yes the info is still valid for your non vented system boiler with a dual channel CH & HW programmer.
