British Gas RS1 Room Thermostat Replacement

[Reg Atkinson]

Looking for some advice. I wish to change the old BG analogue thermostat that is located in out hallway and replace with a Honeywell DT90E. I understand the Honeywell will only use 2 wires, the original live red and the original yellow switch....... So I removed the front of the old thermostat and have this configuration. The live appears to have a short piece of wire linking it to another terminal.
Am I OK just to use the red and yellow to wire in the new stat and remove the red extention and the blue? There is an earth, but I understand its not required on the Honeywell?
Any help would be appreciated.

Thanks.

Get rid of link not required
Neutral and earth need making electrical safe not just chopped off.
Red / yellow switch wires.
Make sure everything is electrical safe before starting!

Cheers for that. Looks like Red in A and Yellow in B. Get rid of link, make the neutral and earth electric safe. Switch system off at breaker before starting!
