I notice that this controller box has four different control methods for adjusting the fan speed.

1/ Use an external thermistor to measure the temperature and control the PWM duty, set the target equipment temperature on the control knob
2/ Have no sensor and just manually control the PWM duty from 0 to 100% using the control knob and setting the DIP switch to IA internal adjustment
3/ Connect an external 10K potentiometer to control the speed directly
4/ Connect an external variable 0 to 5V power supply to and change the voltage to adjust the speed

Multi-function PWM fan control all in one unit.
