Instruction
Press + to view the disconnect voltage.
Press - to view the difference.
Press the "+" key twice. When the decimal point flashes, press the "+" or "-" key to set the disconnect voltage.
Double press the "-" key, and when the decimal point flashes, press the "+" or "-" key to set the difference.
Long press the "+" key, and when the LED screen flashes, press the "+" or "-" key to calibrate the input voltage.
Hold down the - key, and then press + or - to set the delay value T.
When the output voltage reaches the reconnection value, the load is reconnected after a delay of T minutes.
The delay time ranges from 000 to 010 minutes and is displayed as 000 or 001 or 005 or 010. The decimal point is not displayed.

  Example:
Setting below 12.5V will stop, higher than 14V will start.
Set the protection value: Press the "+" key once to display the protection value. Double-click the "+" key and the decimal point flashes. Press "+" and "-" to change the value to 12.5.
Set the return difference: Press the "-" key once to display the return difference, double-click the "-" key, the decimal point flashes, press the "+" and "-" keys to change the value to 1.5.
If there is no operation in 3 seconds, the module will automatically save and exit the setting mode.

  Tip: If you test a 3-second charging pack on a 10-watt LED, the display lights up for a few minutes and then the module runs out of power. The reason may be that the module is only suitable for a single cell, not a battery pack. The solution is a single battery connection.
