RAYN Growing Systems Compatibility

RAYN Growing Systems (rayngrowingsystems.com) provide researchers and growers with
technologically advanced horticultural lighting solutions. RAYN product offerings are
grounded in 45 years of advancements in lighting science, LED technology, and system-wide
controls developed by our parent company, ETC.
The ELED2-BCL is ideally suited to work with RAYN sensors, and is compatible with any photo
sensor that supports EEP D2-14-56 or multisensor that supports EEP D2-14-5E. Linking a
RAYN Photo Sensor (RPS) or RAYN Multisensor (RMS) to the intensity channel provides reliable
coverage and efficiency for controlled environment agriculture (CEA) operations of any scale.

Daylight Harvesting Applications

The controller modulates light intensity from a dimming fixture based on the ambient light
level in the space when a photo sensor is linked to the dimming channel. When daylighting is
active, a switch or gateway command cannot force the light level higher. However, a switch or
gateway command can override the light OFF or dim to a level below the daylighting control
value.
Note:
The controller supports only one linked photo sensor. If using multisensors,
Echoflex recommends that only one be linked to the controller.
Daylight harvesting does not affect the operation of wall switches when the light is ON. If the
light is ON, a switch can override with an OFF action or dim to below the daylighting control
value.

Daylighting Control Override

The open or closed loop daylighting features can be temporarily overridden by enabling the
daylighting manual override parameter. The override has a timer that releases the override,
and once the timer expires the daylighting control resumes.
If the override is enabled on the controller, a manually controlled switch can turn lights ON
and manually set the dimming level.
Garibaldi Pro software is required to configure both the daylighting manual override timer and
daylighting manual override enable parameters.

Closed Loop Control

In closed loop daylighting, the sensor indirectly monitors the controlled light output from the
fixtures plus some of the natural light contribution.
Note:
For closed loop control to function properly, the sensor must be installed in a
location where it is significantly affected by light level changes. If not,
Control on page 10 should be used.
