Key description:
"+" and "-" buttons: switch the display in the running state, and increase or decrease the value during parameter setting (press and hold continuously).
The OK button has three functions:
1. In the running state, press to enter the natural output setting, that is, manual speed control setting, the range is 1-100(%), and press again to save and exit.
2. In the running state, hold down to enter the temperature parameter setting, press + and - to modify the parameter after entering, press OK to switch the setting item, set (* represents a number) acceleration temperature "L**", full speed temperature "H**", turn off temperature "C**", and press OK again to save and exit the setting.
3. In the power off state, hold down the "OK" button to power off, enter the function setting, press the "+" and "-" buttons to modify, press the "OK" button to confirm and save and exit, set the PWM output direction to: forward/reverse P1/P-1, press the "OK" button again to save and exit.
Temperature parameters detailed description:
Acceleration temperature "L**" : Range (5-94) As the temperature increases and exceeds this temperature, the PWM output begins to increase with the temperature increase.
Full speed temperature "H**" : range (10-99) When the temperature rises or exceeds this temperature, the PWM output is always 100%, and the fan runs at full speed.
Closing temperature "C**" : range (0-92) Low temperature closing temperature, when set this value > At 0, the low-temperature shutdown function is enabled. When the temperature is lower than this temperature, the fan output is turned off (the fan power supply and PWM signal are turned off at the same time). When the temperature rises to exceed the acceleration temperature, the fan restarts and changes speed with the temperature. If the shutdown temperature is set to 0, the low temperature shutdown function fails and the PWM and fan power supply will always be output.
Note: the difference between the acceleration temperature and the full speed temperature should not be less than 5℃, and the difference between the closing temperature and the acceleration temperature should not be less than 2℃. If the value breaks the above temperature difference value when modifying the parameter, the program will automatically adjust the other two parameters.
Display description:
Three digit tube: display specific parameters and values.
LED "X10RPM" : speed unit indicator. When the indicator is on, the digital tube displays the fan speed. The value is the value after the fan speed is divided by 10. For example, if 256 is displayed, the actual fan speed is 2560RPM.
LED "C" : temperature unit light, this light is lit, the digital tube displays the temperature measured by the current probe.
LED "RUN" : Fan running indicator, on when the fan is running, off when the fan is off.
