    Tips: What is ON/OFF control in temperature controller?
    In temperature controller, ON/OFF control is setting parameter P to 0. Temperature controller compares the difference value between the measured value (PV) and the set value (SV), and regulates controlled plant by ON/OFF control. When the temperature is lower than the setting lower limit parameter, temperature will open the heating device and the device runs at full power. When the temperature is higher than the setting upper limit parameter, temperature controller will close the heating device and the heating is completely stopped. The temperature fluctuates slowly between the lower limit and the upper limit. There is fluctuation for ON/OFF control temperature. The equipment starts and stops frequently, but the control method is simple.
    ON/OFF control is suitable for the environment that has lower requirement for control accuracy, such as water temperature control of baths.
