*Tri-color LEDs indicate low water level (red), medium water level (yellow) and high water level (green). Switchable for low or high draw. When the function switch is pressed, the low water relay pops up (that is, it is not pressed) (the external water pump works), water starts to be added, the water level rises to the high water level, the relay is disconnected (the external water pump works), water starts to be added, the water level rises to the high water level, and the relay turns off Turn on (the water pump stops working), until the water level drops below the low water level, the relay is turned on again, and the above process is cycled.
*This function is used for automatic water filling equipment to keep the water level between the low water level and the high water level. When the function switch is pressed, the high water level relay (external solenoid valve) starts to drain water, the water level drops to a low water level and the relay closes (the solenoid valve stops working), until the water level rises to a high water level again, the relay is closed again, and the above process is cycled. This feature is used in automatic drains to keep the water level between low and high.
