Switch, Dim & Boost Centrally Now you have complete control over the light cycle and the output of your fixtures from one single point. Never reach to a ballast again!

Simple Programming Setting up the controller is a breeze, with a 5 language text interface in plain language on a high-quality OLED display.

Separate Sunrise/Sunset Set different times for sunrise and sunset.

Crop Safety - Auto-dim In extreme conditions the Master Controller automatically dims your lights, so your plants will survive the high heat.

Memory Nonvolatile memory to store user settings.

Independent Light Cycles on EL2 Models Allow to program two different, and overlapping cycles, for example, a 12/12 on channel 1 and an 18/6 on channel 2.

Logging The logging functionality provides insight into the current and past status of your lights and alarms. Logging functions for high/low temperature, last auto-dim event, last shutdown event, and last power loss.

Easy Installation The complete installation is plug-and-play. Every e-series fixture comes with all necessary cables to install it on the e-series control BUS.

Crop Protection - Auto-Shutdown When cooling or ventilation fails, the Master Controller automatically switches off your lights, preventing imminent damage to your crop (or worse).

Safe The most important and valued features of the Master controller are the temperature safety features. Your lamps will automatically dim when your climate control is no longer able to maintain the correct temperature. Or will even shut down your lamps when a maximum temperature is reached. 

The control signal is a safe, analog, and low voltage signal, and the controller is protected from signal shortcuts in the wiring. Wiring faults will not kill your controller.

Flexible Whether you control two fixtures or 1,000, the Master Controller will do the job. Standard, each output channel can control 40 fixtures (Single BUS e-series) up to 500 fixtures (Repeater BUS e-series), without the addition of booster modules.
