    The HYDROS Control 4 is a powerful and robust foundation for a customized control system capable of meeting the needs of even the most advanced reef. Through numerous control devices available for the HYDROS system, and using the cloud-based app, you can gain control over many functions of your aquarium through a simple and intuitive interface. You’ll find many valuable capabilities with the HYDROS Control 4. Select from several probes to monitor various critical parameters in your aquarium, add a Power 4 WiFi Power Strip for programmable outlets, or use the Drive Ports to control solenoids or an ATO.


    HYDROS Controllers have an industrial look because they are built to withstand the marine aquarium's harsh environment. The IP65-rated HYDROS enclosure and aircraft-style connectors ensure long-term reliability in the face of splashes and corrosive salt spray.



    • Control your HYDROS device(s) from anywhere in the world using the cloud-based app
    • Monitor and control your HYDROS device(s) locally through WiFi
    • Fast dual-core 32-bit processor allows control decisions to be made within each device
    • Internal health monitoring to report voltages, currents, CPU status, and internal device temps
    • HYDROS Command Bus connections transfer data and power to devices


    Sense Port

    The Sense Port is a new concept in aquarium parameter measurement. The HYDROS Control 4 includes four Sense Ports for expanded capabilities. A Sense Port is a generic input port that can accept data from a variety of different types of sensors.


    Supported Sensors

    • Temperature probes
    • Optical level sensors (single and dual)
    • Capacitive non-contact liquid level sensors
    • Rope leak detectors
    • Point leak detectors
    • Flow rate sensors
    • Magnetic switches
    • Push-button switches


    Drive Port

    The four Drive Ports onboard the Control 4 provide switched 12V DC power for running small lights, motors, pumps, fans, and other accessories. The exact current being supplied by each port is continuously monitored by the Control unit, so if a motor or pump quits drawing current or draws too much, you will be immediately notified.


    Available Drive Port Accessories

    • Auto Top-Off (ATO) pumps
    • Cooling fans
    • Cabinet LED lights
    • Solenoids to control reverse osmosis systems


    Probe Port

    One of the most remarkable ports on the HYDROS Control 4 is the Probe Port. The Control 4 includes two Probe ports which can be connected to an ORP or pH probe, but these are no ordinary probe inputs! The circuitry is based on an ultra-high-quality input chip specifically designed for these types of probes. Each pH input provides digital galvanic isolation from the rest of the system which prevents interference with other accessories connected to the system like motors and pumps. Digital Galvanic isolation maintains the accuracy of the measurement by converting the signal to a digital domain before transmitting the information.


    0-10V Port

    The HYDROS Control 4 has two 0-10V I/O (input and output) ports that allow it to control and receive commands from other HYDROS devices as well as accessories from other brands. A legacy automation system can provide input via the 0-10V Ports. They can control variable speed pumps and can also be used to monitor simple switches, like push buttons or float switches.


    Command Bus

    The HYDROS Control 4 includes two Command Bus ports which are used to power the Control unit as well as communicate with other HYDROS devices for the ultimate failsafe.
