What is a standard installation height for a thermostat on an interior wall to ensure accurate sensing?

• A. On an exterior wall
• B. About 5 feet above the floor
• C. Near the ceiling
• D. About 2 feet above the floor

Answer: (B)

Thermostats sense the room air, so the location should reflect the temperature that occupants actually experience. Installing the thermostat about five feet above the floor places the sensor in the typical breathing zone, away from drafts, direct sunlight, and nearby heat sources, giving a representative reading of the space. Placing it on an exterior wall can skew readings due to the wall’s temperature differences; near the ceiling, the air is warmer from stratification and won’t reflect the living area; placing it much lower picks up heat from people and appliances and isn’t representative of the whole room.
