III Key
1 control light
Briefly press the key to turn on or off the backlight, the backlight has memory function, it can store the
on or off status when power off.
2 reset power
Step 1: Press and hold the key for 5 seconds until the power value flashes, then release the key.
Step 2: Briefly press the key again, then the power value is cleared and exit the intermittent reset state.
Step 3: If there is no operation on the key within 5 seconds, it means the power value is not cleared
and will leave the reset state.
3. Set the power alarm threshold
Step 1: Press and hold the key until the LCD display shows “Set CLr”, then release the key to enter
the setting state
Step 2: Power window shows the value the current power alarm and the last digit starts flashing,
then you can briefly press plus 1, when it is not working for 3 seconds, it will change the digit position
automatically, the setting method is the same as above.
Step 3: After finishing setting, long press the key for 5 seconds will automatically store and exit, the active
power threshold range is 0.0 ~ 22kW.
