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

Technical Specifications

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.
