Hi there..I have moved into a new house which has had a new boiler and new thermostat control panel fitted. They have left the old thermostat control on the wall in the hall - old school square box style with wheel. I want to remove this completely as it is ugly and not in use and then wall paper over where it was and repaint. I have no idea how to do it!!!!! I've looked behind it and it is still wired up so I don't know what to do next.....can anybody help???
