Mode description: 1. Double control operation mode: When the pressure switch start threshold or water flow switch detects the signal trigger, the water pump will start to run automatically. When the pressure switch and water flow switch have no signal, the water pump will shut down automatically. 2. Timing mode: When the time reaches the set time, the water pump starts. When the water pump detects that the pressure switch and the water flow switch have no signal, it indicates that the water is full, and the water pump automatically turns off. 3. Water shortage mode: When the water pump is running, it is detected that there is no pressure and no water flow. After running for 6 minutes, it enters the water shortage mode. Then it starts every 1,2,3,6,6,6,6 hours, and runs for 3 minutes each time until the water flow is detected and the normal mode is restored. 4. Failure mode: When the water pump is running, the detection water flow switch has no signal change for a long time and enters the fault mode. After that, the water pump is separately controlled by the pressure switch, and each time the water pump starts, it will run for 15 minutes until the water flow switch returns to normal.Features:1.New flow channel structure; 2.Low noise; 3.Reduce the pump temperature rise; 4.New design of pump control circuit board; 5.Improved stability; 6.User-friendly; GKS series of pumps have automatic function, that is, when the tap is turned on, the pump will start automatically; when the tap is turned off, the pump will stop automatically. If it is used with the water tower, the upper limit switch can automatically work or stop with the water level in the water tower. GKS is with streamline product design, novel and generous, in line with the use of various occasions.
