Fuction:

1.Start and stop the pump automatically

2.Protect the pump from damage caused by dry-running

3.Examine the water automatically

State LED:

1.Red led(state one)lights up:the unit is off

2.Green led(state two)lights up:the pump stops

3.Red led(state one)and green led (state two)flash alternately

    in slow speed:pump in operation

4.Red led(state one)and green led(state two)flash alternately

    in high speed:pump stops:waiting to start

5.Press the ON/OFF button for one second to start the unit:

    press the ON/OFF button for five seconds to stop the unit

Description for the eaxm process:

     While the pump is in the absence of the water;it will start the first exam after 3 mins.it will last 50 seconds;Then the unit will examine in the following second to twelfth time in every 30 mins.and exam time will last 50 seconds;And the unit will examine in the following thirteenth fo forty-seventh time in every 60 mins.exam time will last 50 seconds;The unit will stop in the forty-eighth exam.During the exam process,it lasts 41 hours.
