  • Page 19: Proportional/Integral (Pi) Control

    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.

  • Page 25 Thermostat Communication objects and ETS parameters Proportional fan coil operation Proportional fan operation is similar to that of the three-speed fan coil. When the valve is OFF the proportional speed is equal to 0%; when the valve is ON the value of the proportional speed depends on the difference between the setpoint and the temperature measured in the room.
