The smart pump is operating uniquely by PCB that detects water. When
the pump plug in, it automatically detects water for 10 seconds. If the
water level is high enough, the pump starts pumping water out. If there's
no water or the water level is too low, the pump will shut off
automaticallyfor 3 minutes then detects water again for four seconds.
After the pumpdetects enough water, it automatically starts to pump
again.
When the pump finds no water, it shuts off again.
The process continues cyclically unless it is unplugged
