The Kamoer ATO One 2 is an advanced automatic top-off (ATO) system designed to maintain stable water levels in aquariums or other water systems. As an upgraded version of the original ATO One, it incorporates more compact and accurate optical liquid level sensors, along with a submersible pump featuring an anti-dry function. This system is available in two main versions to cater to different setups: the ATO One 2 SE, which comes with a submersible pump and is ideal for use with a water container, and the ATO One 2 for RO, which includes a solenoid valve and is suited for integration with an RO (Reverse Osmosis) water system.

Function Description

The primary function of the ATO One 2 is to automatically replenish evaporated water, ensuring a consistent water level. It achieves this through a sophisticated sensing mechanism and intelligent control. The system utilizes two optical liquid level sensors: a blue sensor (S1) and a red sensor (S3).

The blue sensor (S1) is the refill sensor, positioned at the normal desired water level. When the water level drops below this sensor, the system detects the need for replenishment and activates the refill pump (for the SE version) or opens the solenoid valve (for the RO version) to add water. The refilling process continues until the water level rises back to cover the blue sensor.

The red sensor (S3) acts as an anti-overflow sensor, installed slightly above the normal water level line. Its purpose is to provide a critical safety measure. If the water level reaches this higher position, it indicates that the primary refill sensor (S1) may have failed or that the system is overfilling. In such an event, the ATO One 2 will immediately trigger an alarm and force the refill pump or solenoid valve to stop, preventing potential overflow and water damage.

The system also incorporates intelligent timeout and anti-dry-burning features. If the replenishment process exceeds a set time limit, or if the submersible pump's anti-dry-burning identification sensor detects insufficient water in the freshwater container, the system will alarm and cease operation to prevent damage to the pump or system.

Usage Features

The ATO One 2 is designed for ease of installation and operation, making it accessible for both novice and experienced users.

Simple Installation: The system is largely plug-and-play. Users only need to install the sensors and the submersible pump or solenoid valve, connect the power, and it's ready for use. This minimizes complex setup procedures.
Magnetic Sensor Attachment: The optical liquid level sensors feature a magnetic attachment mechanism, allowing for very convenient installation and adjustment of their positions within the tank or sump. This eliminates the need for cumbersome brackets or adhesives.
Dual Optical Liquid Level Sensors: The inclusion of two optical sensors provides robust and redundant water level monitoring. The blue sensor manages routine replenishment, while the red sensor serves as a crucial overflow prevention mechanism, enhancing the reliability and safety of the system.
Clear Status Indications: The controller unit provides rich status indications through LED lights and a buzzer. These indicators clearly communicate the system's operational status, such as power on (green), active refilling (blue), and various alarm conditions (red). This allows users to quickly ascertain the system's state without needing to delve into complex menus.
Audible and Visual Alarms: In critical situations, such as overflow, replenishment timeout, or issues with the connected pump/solenoid valve, the system triggers both an indicator light and an audible buzzer alarm. This ensures that users are promptly alerted to potential problems, allowing for timely intervention.
Anti-Siphon Design (SE Version): For the submersible pump version (ATO One 2 SE), the system emphasizes the importance of installing a siphon break in the freshwater container. This ensures that the water outlet of the pipe is always higher than the liquid level of the fish tank, effectively preventing accidental siphoning of the entire freshwater reservoir into the main tank.
Compatibility with RO Systems (RO Version): The ATO One 2 for RO is specifically designed to integrate seamlessly with existing RO water systems, providing an automated top-off solution for users who rely on purified water for their aquariums.

Maintenance Features

While the ATO One 2 is designed for reliable operation, certain maintenance considerations are important to ensure its long-term performance and accuracy.

Sensor Cleaning: The sensitivity of the optical liquid level sensors can be affected by dirt or biofilm accumulation. Users are advised to periodically wipe off any dirt from the sensor probes to maintain accurate readings and prevent misjudgment.
Submersible Pump Base: The submersible pump (for the SE version) comes with a bottom fixed base and filter cotton, which can be flexibly removed for cleaning or replacement, helping to maintain pump efficiency and prevent debris from entering the system.
Siphon Break Placement: Regular checks should be made to ensure the siphon break in the freshwater container is correctly installed and remains higher than the highest liquid level of the freshwater container at all times. This is a critical maintenance point for preventing siphoning.
Pump/Solenoid Valve Connection Check: In case of an alarm indicating a faulty or disconnected pump/solenoid valve, the first step in troubleshooting is to check the physical connection. If the issue persists, replacing the component may be necessary.
Environmental Considerations: The device is not waterproof and should be operated within specified temperature (0-40°C) and humidity (<80%, non-condensing) ranges. Maintaining these environmental conditions is crucial for the longevity and proper functioning of the system.
Water Level Monitoring: While automated, it's good practice to periodically observe the water levels and the system's operation to ensure everything is functioning as expected, especially after initial setup or any changes to the system.
