1. The first line of LEDs displays the actual status: fan speed ratio, speed and temperature, and the refresh rate is 1 second.
2. The second and third lines of setting display are divided into two types: automatic and manual. Only the temperature is automatically set, and the actual temperature is maintained at 1 degree above and below the set temperature. Manually set low temperature, low speed and high temperature, high speed. The alarm setting LED flashes, the buzzer outputs, and the alarm temperature is set by the high temperature part.
For example: set low temp=30, fan speed =50%,high temp=70,fan speed =100,
When the temperature is 0-69.9 degrees, the fan outputs 50%, and when the temperature reaches 70 degrees, the fan outputs 100%.
3. On the bottom line, set the buttons, the main switch, the temperature probe, the power supply 12v input and the fan output.
