major function

Control function: Recharge pre deposited water fees through purchasing water cards, pay first before use, and eliminate the phenomenon of water fee arrears.

Query display: The LCD can display the current sufficient water volume, remaining purchased water volume, and accumulated water volume used, making it convenient for users to query.

Protection function: The valve automatically closes when there is insufficient voltage, abnormal signal, or external magnetic interference.

Prompt alarm: Promptly prompt when the battery is under voltage, the remaining water level is insufficient, misoperation, magnetic interference, and other situations occur.

Automatic statistics: Automatically track the actual monthly water usage of users, facilitating management by operators.

Anti blocking: Adopting anti freezing circuit and valve anti blocking patented design, greatly reducing valve failures.

Automatic maintenance: The self check function is set in the table to detect the flexibility of the valve and prevent battery sleep. The detection time can be set according to the user's needs.

Data retention: User data can be saved for more than ten years, and will not be lost when the battery is dead or disconnected.
