Lock/unlock function
With the correct gear, you need to press “down” until the buzzer sounds twice. The pump is
now locked. To unlock proceed in the same way.
Automatic memory function
When the controller power is cut off suddenly, it still keeps its memory. The pump will auto-
matic recover its operation state as before when the power is switched on another time.
Alarm function
The pump will cut off power immediately and automatically if the pump idles. It will re-start
automatically to work again after 5 s. If still idling, the pump will automatically cut the power off
again. After five times of repeated activation, the pump will power off until re-connect the
power. Meanwhile, the alarm buzzer will sound.
The pump will cut off power automatically and immediately if the impeller is blocked, and the
alarm buzzer will sound until the pump is re-connected to the power supply.
