The purpose of a thermostat in an HVAC system is to regulate temperature within a space. It acts as a control device that senses the ambient temperature and compares it to a setpoint that the user desires. When the temperature in the space deviates from the setpoint, the thermostat activates or deactivates the heating or cooling systems to maintain comfort levels.

For instance, if the interior temperature rises above the desired level in a cooling mode, the thermostat will signal the air conditioning unit to turn on. Conversely, if the temperature falls below the desired level in a heating mode, the thermostat will turn the heating system on. This automatic regulation ensures a consistent and comfortable environment, adapting to changes in indoor heat generation or external weather conditions.
