RO Water Controller 8555 TUNZE

RO 8555 Water Controller – Tunze

The Tunze RO 8555 controller is an automatic water level regulation system designed for reverse osmosis stations or any osmosis water tank equipped with an automatic filling function. It ensures reliable water level management thanks to its two precision sensors and integrated solenoid valve, guaranteeing safe and overflow-free operation.

Operation

The system includes an electronic controller, two magnetic float sensors, a solenoid valve, and a 12 V power supply. The first sensor activates the solenoid valve when the water level drops, while the second stops the filling once the level is reached. An electronic timing device automatically stops the filling after 12 hours (factory setting) or 24 hours depending on the configuration, avoiding any risk of overflow in case of a blocked sensor.

Usage and Compatibility

• Compatible with all Tunze RO stations and standard osmosis systems
• Not recommended for the Nano RO 8515 station
• Possibility to replace the solenoid valve with the 3150.110 controlled socket to operate a pump or other mains-powered device
• Can be used for automatic filling or draining of tanks
• Two controllers can be combined to automate water changes

Technical Specifications

• Power supply voltage: 12 V DC
• Power consumption: low consumption
• Sensors: 2 magnetic float sensors with magnet mounts
• Solenoid valve: 12 V DC (replaceable with socket 3150.110)
• Installation: on a dry surface, secure wiring to prevent water infiltration

• Yellow LED Water Off: high level, solenoid valve closed
• Red LED Time Out: timer activated after duration exceeded

Safety and Installation

• Install on a dry and well-ventilated wall
• Do not place near a heat source (> 35 °C)
• Mounting magnets should be handled with care (strong attraction)
• Avoid any exposure to water or splashes on the controller
• Silent operation and minimal maintenance

Advantages

• Safe and regulated automatic filling
