A thermostat is specifically designed to regulate temperature by maintaining a set temperature within a space, such as a room or building. It achieves this by turning heating or cooling systems on and off based on the temperature readings it detects. This function is critical for ensuring comfortable living and working conditions, as well as for energy efficiency within a building.

While controlling electricity supply, monitoring air quality, and managing water flow are important functions in various systems, they are not the primary role of a thermostat. The focus of a thermostat is solely on maintaining a desired thermal environment.
