CoralVue HYDROS Control 4 – Controller Only (HDRS‑C4) 🧠⚡
A powerful, expandable HYDROS controller designed for full aquarium automation.
The HYDROS Control 4 is one of the most capable controllers in the HYDROS ecosystem, offering a wide range of monitoring, automation, and safety features. With multiple probe ports, Sense Ports, Drive Ports, and Command Bus networking, the C4 is ideal for reefers who want a strong, reliable foundation for a fully automated system—without the extra accessories included in the Starter Pack.
This controller‑only version is perfect for custom builds, controller boards, or expanding an existing HYDROS Collective.
✨ Description
The Control 4 delivers robust automation capabilities, including temperature, pH, water‑level, and leak detection monitoring. With four Sense Ports, two Drive Ports, and dual probe inputs, it can manage ATO systems, dosing pumps, solenoids, safety sensors, and more.
Its Command Bus connectivity allows the C4 to join or form a HYDROS Collective, enabling redundancy, shared processing power, and seamless integration with other HYDROS devices like the XP8, X10, X3, and WaveEngine.
This controller replaces multiple standalone devices—ATO controllers, pH monitors, timers, and power strips—while giving you a clean, app‑controlled automation hub.
