Thermostat temperature suddenly deviating
Posted: 13 Dec 2018, 15:48
My thermostat which I installed one month ago has been working fine until now. Suddenly within a few hours the temperature shown by the thermostat increased by 4 degrees which is the delta I see between a second thermometer. I am five hours away so I monitor this with my mobile. Any ideas why the thermometer suddenly is showing a wrong temperature?
