Heating on past midnight yet thermostat shows heating off
Woke up very hot at 00:30 because heating system was still running and on checking the thermostat it displayed 'off' as expected as the programme should switch off at 21:30. I think that I had used the thermostat earlier to raise the temperature but may somehow have put the heating in a manual mode- trouble is I really don't know and I fiddled with something on the phone app in my half asleep way and managed to turn the heating off. Can anyone help with what may have happened? - the system has only been in use for a few months so I am a bit new to it!
