What if the room temperature displayed on the thermostat screen
appears to be wrong?
The presence of cooling or heating sources near your thermostat may affect the temperature displayed on the screen. Strong ventilation, drafts, a dimmer or another device nearby can falsify the temperature reading since the temperature probe is located in the thermostat housing.
Ensure the thermostat is located away from anything that could influence its display temperature so that it actually represents the room’s actual temperature.
