Automatic Water Pump Controller 220V 380V With Ultra Low Voltage Protection
Water Pump Controller specification:
The automatic pump controller is simple and efficient. When the
pump is started to pump water, it is often forgotten to shut it
down, resulting in waste of electricity and water. The installation
of the fully automatic pump is simple and efficient to solve the
start and stop of the pump. When the pool is filled with high water
level, the pump water supply is stopped by the sensor signal. When
the pool is at low water level, the sensor signal starts the pump
to pump water.
The automatic water pump controller adopts digital core with
overload, no load and ultra low voltage protection. The upper and
lower levels and pressure are automatically controlled in one.
Can be connected to float control, pressure gauge control and probe sensor control

2.Wiring connection of float switch for lower pool water level control (second pump start control)
Under this mode, the no-load protection value must be set as 0.00A.
It has two float switches in the system, please connect the common
terminals of the two switches to
Low probe terminal. The normal close terminal of float switch 1
connects with High and Middle
terminal of controller, the normal close terminal of float switch 2
connects with the Add terminal of
controller.
When the float switch 1 is activated, one pump will work
accordingly, while the float switch 2 is
activated, the second pump will be started, and two pumps will
work. Only when the water level lower
than float switch 1, the two pumps will stop
