Yes noticed guarantee - think you are probably right and will need to replace it. Will remember to turn heating off at receiver tonight before going to bed so don't have to do the midnight trek to the shed!
Thanks for replying. Much appreciated.
Yes there is an on/off switch and it does put off the heating - having just been putting on manually from there until I can figure out why the controller programming bit is not doing what it is supposed to do!
Hi Just wondering if anyone has come across similar problem with this thermostat. Had it fitted one year ago and has been working perfectly until this weekend.
The thermostat has been programmed to come on and off at set times but now the boiler is coming on when the themostat is showing...
