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

The primary role of a thermostat in an HVAC system is to regulate temperature settings. This device monitors the current temperature in the environment and compares it to the desired temperature set by the user. When the temperature deviates from this set point, the thermostat sends a signal to the HVAC system to either turn on the heating or cooling equipment, thereby maintaining the preferred climate within a space.

This function is crucial for ensuring comfort and energy efficiency, as it allows the HVAC system to operate only when necessary to achieve and maintain the desired temperature. The thermostat essentially acts as the control center of the HVAC system, responding to changes in temperature to keep the environment stable and comfortable.
