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), set the dials on the systems to EXT (External control), plug
the controller and the systems directly into the main power supply and you are set to go.
The EYE HORTILUX GRC1 controller can switch all the interconnected systems on and off with its
internal
timer
, adjust them to your required output level (in percentage or exact output power) and even simulate
sunrise and sunset
to gradually adjust the climate in your grow room when your lights go on or off. This
electronic controller replaces expensive lighting timers and electrical contactors while preventing ballast
current in-rush when switching on your lights.
Two very important features of the EYE HORTILUX GRC1 controller are the
auto-dim function
and
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.
The controller can also manage your lights to maintain a safe temperature utilizing the included
temperature sensors. The display and warning LED indicate when high temperatures are reached and
also indicate if this has happened while you were away. If for any reason your
climate control
completely
fails and the temperature rises to unacceptable levels, the EYE HORTILUX GRC1 controller will perform an
emergency shutdown of all connected equipment. The alarm contact of the controller can be connected
to your alarm system for instant notification.
You can connect up to one-hundred systems to one controller and control two separate rooms (up to 50
systems each) using their own temperature sensor for auto-dim (at high temps) and emergency shutdown
(at extreme temps).
For
auxiliary equipment
, you can connect up to two accessories via the EEM port, one to switch equipment
when lights are on (e.g. a humidifier, CO
2
equipment or air conditioning) and one when lights are off (e.g.
a room heater).
