    Thermostat Communication objects and ETS parameters Proportional/Integral (PI) control Continuous integral proportional: PI control with proportional valve This type of control uses a more advanced algorithm that keeps the temperature inside the room more stable, increasing comfort. This algorithm works by switching the system on and off so as to be like a gradual increase or decrease in the system's thermal (or refrigerating) power.
