My myson thermostat not turning on?
I changed the batteries in my myson thermostat, I reset the date and time and reprogrammed the on/off times however the heating isn't coming on at all even when I override it. I've tried resetting it with no joy.... the thermostat was working before battery change.
Its a myson thermostat hard wired
I'm in a new build apartment with communal boiler
