Introduction 1
Introduction
The Bicolor Luminaire Controller, model ELED2-BCL, is a wireless lighting controller designed
for horticultural spaces/areas where intensity and blended correlated color temperature (CCT)
control are required.
The ELED2-BCL creates a range of desired lighting effects based on manual switch action,
ambient light levels, and timeclock or gateway commands for a single LED fixture or an entire
zone. It modulates light intensity and blends cool and warm LEDs to provide the desired CCT
output. The controller is suitable for any scale of horticultural application, from a living plant
wall to a commercial-size growing operation; one controller supports up to three Fotono
luminaires, by RAYN Growing Systems (see rayngrowingsystems.com).
The ELED2-BCL has an integral relay and two robust 0–10 V
outputs that allow it to control dimmable light and LED
color temperature levels. Outputs are for connecting zones
or fixtures to provide the intensity and CCT control. Output
1 is identified by the violet/red striped wire, and output 2 is
identified by the violet/green striped wire.
Three linking channels are for assigning remote devices to
affect the controller's operation. The first linking channel is
for devices affecting intensity, the second channel is for
devices affecting the CCT. The third channel is for assigning
Open Loop CCT set points. The channels are identified by
different LED colors that display when the controller is in
link mode, see Blink Indications on page14.
Daylighting control of fixture intensity can be quickly setup in either an open or closed loop
scenario. The factory defaults defined for the ELED2-BCL are energy code compliant.
Echoflex ELED products include preset functionality that allows spaces to be lit with lighting
scenes. Presets can be activated from scene stations, wireless timeclocks, or gateways and
include values for intensity and color temperature. The lockout feature allows timeclocks to
schedule a controller’s response to specific sensors or stations.

Control Features
Blended Effects
The ELED2-BCL controls light intensity and CCT. By connecting the low voltage outputs to a
fixture's internal channels for cool and warm LEDs, it modulates both outputs to attain the
desired light level. By driving each output separately, the controller also has control over how
cool or warm the fixture output becomes.
Dim-to-Warm
Dim-to-Warm operates if at least one switch station is linked to the intensity channel and
nothing is linked to the color temperature channel. The color temperature moves according to
the change in light intensity. An increase in intensity also moves color temperature to cooler. A
decrease in intensity moves color temperature to warmer. Dim-to-warm mode operates with
daylight sensors, regular switches, and gateways linked to the intensity channel.
Explicit Color Control
With a switch station linked to the color temperature channel, Explicit Color Control provides
manual control over a fixture's color temperature. By pressing the paddle on the station, you
can set a color level and modulate output as required. Press and hold ON increases color
temperature to cooler; Press and hold OFF decreases color temperature to warmer. A quick tap
on the button bumps color temperature up or down incrementally. A gateway command can
also be linked to the color temperature channel allowing other devices to control the fixture's
color temperature.
Automated Color Tuning
Automated Color Tuning requires a color temperature sensor like the Echoflex TAP-41 photo
sensor linked to the color temperature channel. The ELED2-BCL compares its CCT set point to
the value from the space provided by the sensor and increases the fixture's color temperature
to the set point.
Example: The CCT set point is 3500 K and the sensor reports a value of 3200 K.
The controller will adjust the CCT output driving the fixture's output towards the
desired set point.
Automated Color Tuning can also use a dynamic CCT set point input linked to a gateway
command or outdoor color temperature sensor like the Echoflex FLS-41 sensor to set the
desired color temperature within the space and track outdoor color temperature values.

Characterized Color Tuning
Characterized Color Tuning modulates the color temperature channel based on the set point
value. As in the Automated Tuning Operation, a gateway command or outdoor color
temperature sensor can be linked to the CCT set point channel and the output will adjust to
this value based on the fixture's defined specifications. This operation does require the
fixture's characterized specifications for the 0–10 V channel be defined with the controller’s
configuration.
Example: A fixture is used that maps a range of 3200–6000 K across the 1–10 V
range. These values are pre-commissioned with the ELED2-BCL at the factory. The
color tunable output modulates based on the value provided by a linked photo sensor
on the set point value.

Configuration Options 5
Configuration Options
The ELED2-BCL is a complete stand-alone lighting controller requiring only remote linked
devices to provide input on light level, color temperature, and switch operation.
In addition to blended LED operations, the controller will perform the following common
lighting control applications:
• 0–10 V dimming of LED fixtures
• Wall Switch Station: ON/OFF, manual adjustment of dim level and timed switch
• Daylight Harvesting: open loop or closed loop
• Demand Response: sets a temporary hard limit to the maximum dimming output
• Scheduling via interfaces, timeclocks, or gateways
• Building Systems support with gateway commands
This document describes the controller’s features and explains how to use and configure them
with Simple Tap. Some features can only be configured using Garibaldi Pro software.
Note: For information about Garibaldi Pro software or pre-commissioning services
that provide complete system solutions (linked and configured), contact Echoflex.
Garibaldi Pro software is available for download from the Echoflex website at
echoflexsolutions.com.
Simple Tap Instructions
Simple Tap is a manual method of changing individual settings one at a time. There are no
tools required, simply use your finger to activate the sensors and standard switches linked to
the controller. The tap in Simple Tap means a quick press on a sensor's [Teach] button and/or a
switch’s ON/OFF.
Note: Echoflex scene stations cannot be used to configure settings with Simple Tap.
If the sensor is linked to multiple controllers and you do not want to make changes to all, turn
off the controllers lights/loads to ignore the Simple Tap changes.
Radio Communications
The ELED2-BCL controller is equipped with a 902 MHz radio capable of transmitting and
receiving wireless messages. The controller supports single-hop and dual-hop message
repeating and controller status broadcast.
Repeater Function
The repeater function repeats received messages if:
• The message has not been repeated previously
• In the case of dual-hop repeating, the messages have been repeated previously only once
If single-hop or dual-hop repeating is needed, the repeater function can be enabled/disabled
using Simple Tap instructions.

6 Bicolor Luminaire Controller Configuration Guide
1. Press and hold the [Clear] button on the controller.
2. Tap the [Learn] button:
• Once to disable repeating
• Twice to enable single-hop repeating
• Three times to enable dual-hop repeating
3. Release the [Clear] button. The Power and Learn LEDs blink the corresponding number of
[Learn] button presses.
Status Message
The controller can broadcast a message per EEP: A5-11-01 Status Feedback Message. A
message broadcasts every 100 seconds. The status message can be enabled/disabled using
Simple Tap instructions.
1. Press and hold the [Learn] button on the controller.
2. Tap the [Clear] button once to disable, twice to enable.
3. Release the [Learn] button. The Power and Learn LEDs blink the corresponding number
of [Clear] button presses.
Dimming Intensity
The controller's dimming output provides linear, proportional dimming control of a dimming
driver or ballast.
•Output maximum level - the high level trim of the dimming output, set to 100% by
default
•Output minimum level - the low level trim of the dimming output, set to 10% by default
Garibaldi Pro software is required to configure the maximum and minimum levels and to
disable dimming output for immediate control.
Blended LED Control
The controller provides linear, proportional control of a fixture's cool and warm LED output.
The maximum and minimum CCT level of the fixture can be saved in the controller's
configuration settings. The maximum and minimum levels of the output can be configured
using Garibaldi Pro software.
Near-Cross Technology
The controller monitors the AC voltage waveform to prevent carbon build-up on contacts and
ensure long relay life. The relay will open or close only when the waveform is close to zero.
