I have a back boiler behind my gas fire with the controls under the fire (Standard?)
We also have a wall mounted thermostat control.
Control used to work but now does nothing. We have to adjust the central heating via the controls under the fire.
Maybe this is obvious to most but is the problem just a new controller on the wall and how can i test this with my meter?
