Control Function: |
•Low Level - Pump stop;
•High Level - Pump start;
•Low Low Level - Pump stop, and dry run protection alarm will be triggered;
•High High Level - Pump start, and high level alarm will be triggered;
•Pressure monitoring - Pump can be turned off when high pressure alarm triggered;
•Pump running time monitoring - when pump running time exceed the maximum time in a period, the system can send the alarm;
•Pump start, stop delay time can be set, solve the problems such as liquid level fluctuation and water hammer;
•Automatic restart after power recovery etc.
