3.Function description:
The liquid level controller can achieve two functions: (switching by Button S1):
1>.Three color LEDs indicate low, medium and high water level. When the water level is low, the relay is energized (external water pump works), and when the water level rises to the high water level, the relay is disconnected (water pump stops working). This process is repeated. This function is applied in automatic water adding devices, keeping the water level between low and high.
2>.Three color LEDs indicate low, medium and high water levels. When the water level is high, the relay is energized (external solenoid valve works), and when the water level drops to the low water level, the relay is disconnected (solenoid valve stops working). This process is repeated. This function is applied in automatic water draining devices, keeping the water level between low and high.
