The primary function of a thermostat in a heating system is to regulate the temperature by controlling the heating system's operation. It achieves this by sensing the temperature of the environment and sending signals to the heating system to either turn on or off based on the desired temperature set by the user. When the room temperature drops below the set point, the thermostat triggers the heating system to operate, bringing the temperature back up to the desired level. Conversely, when the temperature exceeds the set point, the thermostat will turn the heating system off, preventing overheating. This crucial role helps maintain a comfortable living or working environment and significantly contributes to energy efficiency in the system by preventing unnecessary operation.

While increasing efficiency, filtering air, and maintaining humidity are important functions within an HVAC system, they are not the primary role of a thermostat. The thermostat is fundamentally focused on temperature regulation, which is central to the operation of any heating system.
