Wiring a Programmable Thermostat

salvador2

I currently have this thermostat and I would like to replace it with a programmable thermostat like this. It seems that there only two cables involved.... any good tips other than get an electrician would be much appreciated.

I would go for another Honeywell programmer-something like this?

Will do, thank you.

Most Honeywell controls are 'double insulated' so don't require any earth.

There is an earth terminal on the T6380B but it is just to terminate the earth wire, which will be connected at the boiler end. The Centaurstat 7 has no earth terminal to terminate the wire so it simply needs to be sleeved with insulation.

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.

Can't comment on the Honeywell, but if you want a review - I have the Centaurstat 7 and would highly recommend it .... took 5 mins to fit and works really well. Only negative I would say is there is a definite "click" whenever it switches which you will notice if it is in a living area.

Loads of other reviews here
