Although my Digital thermostat is set to 20 Cel it is actually now reading 23 Cel and my combi boiler is still on heating my radiators. I have switched the system off and then on again but no joy. When i reduce my thermostat to below 20 Cel it recognises this and places the flame icon into the screen as it has always done.
Does anybody know what I need to do to get my heating to switch off at the right temp.
Thansk in advance
