Where should I install my wall-mount thermostat?
Always mount a thermostat on an inside wall away from drafts, direct sunlight, or any appliances that could affect its temperature reading. Make sure the airflow around the thermostat isn’t blocked by shelves, pictures or other wall décor.
Mount wall thermostats used with a baseboard heater on an adjacent wall, if possible. Using another stud bay—one that’s not directly above the fan heater—mount the thermostat about five feet above the floor. If you have two or more heaters in a large room, place the thermostat in a central location.
