What is the primary function of a thermostat found in devices like air conditioners and heaters?

Explanation

A thermostat is a device that automatically regulates temperature by turning a heating or cooling system on or off as needed to maintain a temperature setting chosen by the user. It typically works by continuously monitoring the current temperature and comparing it to the desired setpoint, triggering the connected system when there’s a meaningful difference between the two. This automatic regulation helps maintain a relatively consistent, comfortable temperature without requiring constant manual adjustment.
