Where should a room thermostat be mounted whenever possible?

Installing a room thermostat in a central location is crucial for achieving accurate temperature readings and effective climate control. A thermostat's primary function is to sense the temperature of the room and maintain it at a set level. When placed centrally, the thermostat can effectively evaluate the overall temperature of the space, avoiding extremes that might occur if it were installed near a wall, a heat source, or a return air grille.

Mounting the thermostat away from direct influences such as drafts, sunlight, or immediate heat can lead to more balanced heating or cooling throughout the area. A central location ensures that the thermostat can monitor temperatures from multiple points in the room, allowing it to adjust the system's operation effectively to meet the desired comfort level. This placement contributes to enhanced energy efficiency and comfort, making it a preferable choice over the other options.
