COMPLETE LIGHTING CONTROL AT YOUR FINGERTIPS
Using an EYE HORTILUX® master controller for your EYE HORTILUX® systems offers you maximum control,
ease-of-use, safety, and plug-and-play installation. Just connect the controller cables to the systems with the
T-splitter included with the system (see Figure 5), plug the controller and the systems directly into the main
power supply and you are set to go.
The EYE HORTILUX GRC-LED controller can switch all the interconnected systems on and off with its
internal timer and adjust them to your required output level (in percentage). This electronic controller
replaces expensive lighting timers and electrical contactors while preventing driver current in-rush when
switching on your lights.
One very important feature of the EYE HORTILUX GRC-LED controller is the emergency shut-down. When
the temperature in your grow room rises above the control level of your climate control, your crop can be
damaged beyond recovery. The temperature probe senses this and will automatically dim the system until
the desired temperature is achieved.
You can connect up to one-hundred systems to one controller or use it with just one system. The GRC-LED
is simple to use, easy to set-up and useful for any LED grower.
