Which component of an HVAC system is responsible for adjusting the temperature settings?

The thermostat is the component of an HVAC system that is responsible for adjusting the temperature settings. It acts as a control device that monitors the indoor temperature and communicates with the HVAC system to maintain the desired setpoint. When the temperature fluctuates above or below the setpoint, the thermostat signals the system to either turn on or off the heating or cooling components, ensuring a consistent and comfortable indoor climate.

In an HVAC system, the thermostat is crucial because it not only allows for manual adjustments of temperature settings but can also incorporate programmable or smart technology to automate temperature changes based on time of day or occupancy. This helps improve energy efficiency and enhance comfort levels within a space.
