- In normal daily use, S3 sensor does not work, S3 is installed in the high used to prevent overflow, to play a role of protection. S1 is is to detect the lowest water level sensor, used to identify the refill water. S2 is the refill bucket level sensor, to prevent the refill bucket shortage of water.
- Compared to the old ATO, we have upgraded two parts of this ATO. 1. replaced the original submersible pump with a new anti-dry submersible pump. 2. replaced the new sensor, the new ATO uses a more accurate optical level sensor more responsive, which can effectively reduce the generation of faults.
- Please install the sensor correctly (there is a picture illustration in the main picture), ATO may malfunction will not work. The height difference between the refill bucket and the bottom/master cylinder should not exceed 1.5 meters, and the refill bucket level should not be higher than the bottom/master cylinder level as much as possible .
