What does a thermostat do in an HVACR system?

It measures the air pressure

It regulates the temperature by controlling heating and cooling cycles

A thermostat plays a crucial role in an HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) system by regulating the temperature. It accomplishes this by controlling the heating and cooling cycles based on the temperature settings and the current temperature detected in the space. When the temperature falls below or rises above the desired set point, the thermostat sends signals to the HVACR system to either activate heating or cooling, ensuring a comfortable indoor environment.

The device essentially acts as a control point in the climate management of a building, maintaining desired temperature levels efficiently and effectively. By doing so, it directly impacts energy consumption and cost, as it helps avoid unnecessary heating or cooling. This regulation contributes significantly to indoor comfort and system efficiency, making it vital for the operation of HVACR systems.
