Kamoer ATO oneseis a automatic water replenisher, a good helper for the fish tank at home! It has the function of adding water overtime alarm to prevent water level overflow caused by sensor failure.
This ATO is equipped with S1 float sensor, also called anti-overflow sensor (to prevent excessive water replenishment and water overflow) and S2 optical sensor (also called water replenishment sensor). Usually note: In the case of ATO running normally, S1 is not working, and the float state is sinking. S2 works.
In daily use, S2 is a sensor that detects the lowest water level. The function of S1 is to cause the float to rise when the water level exceeds the S2 optical sensor and reaches the S2 float sensor when S2 fails (for example, foam is generated in the sea tank, etc.) Alarm, stop refilling.
Please install the sensor correctly (the main picture has a picture description), otherwise the product will not work.
And the distance between the two sensors is not less than 10cm.
Sensors may fail if not properly installed, make sure they are properly installed (or unplugged and reinstalled)
The height difference between the make-up bucket and the sump/master tank should not exceed 1.5 meters, and the liquid level of the make-up bucket should not be higher than the liquid level of the sump/master tank.
