Gavita Master Controller EL3

A grow light controller for up to 512 fixtures The EL3 switches, dims, and boosts up to 512 fixtures across two zones, 256 per zone, from a single 8-inch color touchscreen. Whether the fixtures hang over greenhouse benches or an indoor grow room, you run schedules from one panel instead of walking the rows. It reads power draw and driver-enclosure temperature per fixture, so a hot or failing driver surfaces before it costs you a cycle. Sunrise and sunset dimming ease the room in and out of each photoperiod. In a greenhouse, it manages supplemental lighting and day-length across zones as natural light shifts through the season. In a sealed indoor room, it holds a tight photoperiod so a full canopy of plants stays on the same clock. Growers wire it to compatible Gavita 1930e, 1700e, 900e, or Sun System 1850 fixtures and run whole grow cycles on one schedule. Managing the room from one screen cuts the walking, guesswork, and missed timers that cost yield. Scheduling and safety on the Master Controller EL3 High-temperature dimming pulls output back as a room heats, and high-temperature shut-off cuts the lights if it crosses the line. That protects the canopy through a heat spike. A spray feature dims fixtures during applications to guard against crop burn during IPM. It connects up to 16 Titan Controls sensors for VWC, EC, and VPD data and logs setting and alarm history over USB. That log helps you dial in cycles and trace a fault later.
