Digital chip automatic water pump controller
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

Wiring connection for upper pool water level control
When the water level is lower than the middle level, the controller
will start the pump, and it stops
while reach to the high level, the low level probe is used to make
a close-loop circuit.
Wiring connection of float switch for upper pool water level
control
The common terminal of float switch connect to the low level
terminal of controller, short connect high
& middle level terminals of controller and connect to the normal
open terminal of float switch.
Wiring connection of constant pressure control
For constant pressure control system, there must be a pressure
gauge, please connect the
moveable pointer of pressure gauge to the low level terminal of
controller, meantime, please connect
lower limit pointer to middle level terminal and upper limit
pointer to high level terminal.
When the water pressure reduces to the lower limit point, the
controller will start the pump, and it
stops while the pressure reaches the upper limit point.
★ Please select a suitable size pressure tank, if the pressure tank
is too small, it will cause the
pump starts frequently.
