Precautions
1. This control only controls the speed adjustment of the fan controlled by the four-wire standard PWM signal. The signal specification is 25KHZ 5V. Conventional chassis, CPU and many server four-wire fans support it, but it cannot control the speed regulation of 2-3 wire fans!
2. The difference between the acceleration temperature and the full speed temperature should not be lower than 5°C, and the difference between the shutdown temperature and the acceleration temperature should not be lower than 2°C. When modifying the parameters, if the value breaks the above temperature difference, the program will automatically adjust the other two parameters.

Three-digit digital tube: display specific parameters and values
LED "×10 RPM": Speed unit light This light is on and the digital tube displays the fan speed. The value is the value after dividing the speed by 10. For example, if 256 is displayed, the actual fan speed is 2560RPM (revolution/min)
LED "℃": temperature unit light, this light is on and the digital tube displays the temperature measured by the current probe
LED "RUN": Fan running indicator light on when the fan is running and off when the fan is off
