Reset energy
Step1: Long press the key for 5 seconds until the energy value flash, then release the key.
Step2: Short press the key, energy value is cleared and exit the reset flashing state.
Step3: If there is no operate within 5 seconds, it is not cleared,will exit reset state.
Set power alarm threshold
Step1: Long press the key until the LCD display “SET CLr”, then release the key to enter the setting state
Step2: Power area display power alarm value and the last digit begin to flash, short press to plus 1,
If no operate over 3 secs, it will switch digit position automatically, the setting method is as same as above.
Step3: After finish setting, long press the key over 5 secs to store automatically and exit, the range of power threshold is
0.0～22kW.
