In order to assure proper room temperature, it is important to identify the ideal
location of the thermostat. It should be approximately 5 feet from the floor
and at least 1 foot from door openings on an interior wall. Avoid exposing the
thermostat to direct sunlight, to air flows (doors, windows, etc.) as well as to heat
sources.
