What is the primary function of a thermostat in an HVAC system?

To control air quality

To regulate indoor temperature

The primary function of a thermostat in an HVAC system is to regulate indoor temperature. A thermostat acts as a control device that allows users to set their desired temperature level. It continually monitors the indoor temperature and compares it to the setpoint. When the indoor temperature deviates from the setpoint, the thermostat sends a signal to the heating or cooling system to either activate or deactivate, thereby helping to maintain a comfortable environment.

While aspects like air quality, energy monitoring, and filtering of pollutants are important in HVAC systems, they are not the main function of a thermostat. The thermostat specifically functions to ensure that the temperature remains within the desired range, making comfort the top priority in its design and operation.
