We have a Worcester Bosch Greenstart Si Compact and British Gas RC Plus Thermostat. Came to turn on heating tonight and noticed that temperature was displaying at 23 degrees, where it is currently around 14.5. Took the minus down to 5 then the plus up to 18 but of course it didnt come on as already displaying 23 degrees. Tried taking batteries out, tried pressing plus and minus together for 5 secs to get 'off' but when tried again, thermostat still saying
- Does anyone have any experience or similar, or will we need new unit/ It was only installed on 22 April 2015.
