What to do if my Smart temp SMT-400 temperature display seems inaccurate?

If your Smart temp Thermostat's temperature display is inaccurate, it could be due to several reasons. First, air from the wall cavity might be leaking into the rear of the thermostat; plug any holes in the wall with tape to prevent leaks. Second, the internal temperature sensor might be folded back; open the case and carefully move the sensor so it protrudes through the opening. Third, external heat sources like lamps or drafts might be affecting the sensor; move these away from the sensor or consider using a remote temperature sensor.
