iv Tunable White Dimming Controller Configuration Guide

Introduction 1
Introduction
The Tunable White Dimming Controller is a wireless lighting controller designed for
spaces/areas where intensity and correlated color temperature (CCT) control are required. The
ELED2 controller creates a range of desired lighting effects based on occupancy state, manual
switch action, ambient light levels, and timeclock or gateway commands for a single LED
fixture or entire zone.
ELED2H-AU
model shown
The ELED2(H) is available in two voltages: 120–277 V and
240–347 V. Its integral relay and two robust 0–10 V
outputs allow the ELED2(H) to control dimmable light and
tunable 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 stripe
wire, and output 2 is identified by the violet/green stripe
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17.
For scenarios where only occupancy sensors are linked to the controller, built-in control begins
by automating lights ON and OFF using occupancy detection. Daylighting control of the fixture
intensity can be quickly setup in either an open or closed loop scenario. The factory defaults
defined for the ELED2(H) are energy code compliant, including occupancy Partial-ON and
Partial-OFF requirements.
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.
Note: For lighting controls specific to horticultural applications, Echoflex also has a
Bicolor Luminiaire Controller, model ELED2-BCL. This controller uses the same method
to modulate light intensity and blend warm and cool LEDs to provide desired CCT
output. Learn more about the ELED2-BCL at echoflexsolutions.com.

Control Features 3
Control Features
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. 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
occupancy sensors, 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(H) 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-BU or ELED2H-AU at the
factory. The color tunable output modulates based on the value provided by a linked
FLS-41 sensor on the set point value.

4 Tunable White Dimming Controller Configuration Guide
Configuration Options
The ELED2(H) is a complete stand-alone lighting controller requiring only remote linked
devices to provide input on light level, color temperature, occupancy state and switch
operation.
In addition to the tunable white color operations, the controller will perform the following
common lighting control applications:
• 0–10 V dimming of LED fixtures
• Vacancy Sensor Mode: partial OFF or fully OFF
• Occupancy Sensor Mode: partial ON or fully ON
• 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(H) 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.
