Damaged Honeywell programmable thermostat

Jet

My thermostat is damaged and needs replacing. 

This might be a stupid question, but if I just buy a new one, will it just work or does it need to be linked to the combi boiler somehow?  If so, can a layperson do it, or do I need a heating engineer?  The model is Honeywell T3R.

Thanks.

The T3R looks to consist of two parts; the bit with the display, and the bit that's wired into the heating system.

The two parts are paired so (unless there's a way to repair a replacement) you'll probably need both.

Fitting the wired part looks no more complicated that wiing a plug, but will involve bare wires. If you're not comfortable with DIY, you will probably want an electrician (although a heating engineer should also be capable).

You'll find instructions here:

I think most can be paired to new receivers. But will need to confirm.

Try this first. And I'm sure you can pick up a good TR3 on t'Bay, new or 2nd.
