ii Tri-Zone Dimming Controller Configuration Guide

Introduction 1
Introduction
The Tri-Zone Dimming Controller is a fully configurable and complete stand-alone dimming
and lighting controller designed to perform common lighting control applications based on
input from wireless linked sensors and switches.
High voltage
model shown
It includes 0–10 volt dimming channels for three individual
dimming zones and a robust 20A relay (16A relay in
ELED3H model) for ON/OFF control of large controlled
spaces.
Echoflex controllers include functionality to allow the
presetting of lighting scenes based on values for intensity
and color temperature. Presets can be activated from scene
stations, time clocks, or gateways. The lockout feature
allows time clocks to schedule a controller’s response to
specific sensors or stations.
The controller supports both open or closed loop photo
sensors assigning two channels as daylighting channels. The primary daylighting channel
includes a set point while the secondary channel uses an offset from the set point, both
configurable.
The primary daylighting channels set point can be configured based on the outdoor light in the
space. The secondary channel will lag the primary channel by the offset value, providing
consistent dimming results across the space as the natural light changes. The third dimming
channel can be controlled by linked occupancy sensors, switches or gateway commands.
This guides describes the features of the Echoflex Tri-Zone Dimming Controller models and
how to use and configure them.

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 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.
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 ELED3(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.
1. Press and hold the [C lear] 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.
Radio Range Confirmation
Echoflex sensors that are equipped with patented Range Confirmation technology work with
ELED3(H) controllers to facilitate optimal sensor placement. The Range Confirmation test is
invoked at the sensor. It must be linked to the controller and during the test, any repeaters in
the controller's vicinity must be disabled. The controller receives a unique message from the
sensor, evaluates the signal strength and sends back a unique message containing the
strongest signal value received. The sensor displays this value using color LEDs.
See the related device documentation to verify support for radio Range Confirmation testing
and for test details.
Dimming Outputs
The controller's dimming outputs provide 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.
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.

Switch Operation 5
Switch Operation
The controller operates with single, dual-paddle wall, wave, and hand-held Echoflex switches
as well as button station transmitters including the Multi-Button Interface (MBI) Switch Station
and the Multi-Scene Station (MSS). A switch can be linked to a single channel or all the
channels. Garibaldi Pro software is required to configure all the fade control settings.
•
Press ON to increase the lights to the last manually set dimming level.
•
Double-press ON to increase the lights to the output maximum level.
•
Press OFF to decrease the lights to the output minimum level and then turns the lights off.
•
Double-press OFF to turn the lights off.
Echoflex switches can also be used as dimmers when dimming output is enabled.
•
Press and hold ON to increase to the maximum dimming level.
•
Press and hold OFF to decrease to the minimum dimming level.
If a photo sensor is linked to the dimming channel it will have control priority over manually
dimming the output towards the maximum output value.
Timed Switches
The controller can be configured to make any linked wall switch station into a timed switch.
Switching the lights ON starts the countdown timer for the configured period. One minute
before the timer expires and the lights turn off, the lights blink once as a warning (Flick-Warn).
Switching the lights ON at anytime resets the timer. Switching the lights OFF clears the timer.
Garibaldi Pro software is required to configure the period for a timed switch. Each channel can
be configured with it’s own timer period.
Occupancy-Based Lighting Applications
When occupancy sensors linked to the controller do not detect motion, they send a vacancy
message to the controller. After the occupancy auto-OFF timer expires, the controller turns the
lights OFF or fades to a preset level. For information about coordinated control of a space, see
Open-Plan Shared Occupancy on page 7.
Occupancy Sensor Auto-OFFTimer
The occupancy auto-OFF timer is set to 15 minutes by default. The value can be changed using
Simple Tap. Dual Tech sensors also have a built-in independent occupancy timer auto-OFF. To
use the occupancy timer on the sensor, not the controller, set the controller’s occupancy timer
to zero seconds.
To set the controller’s occupancy auto-OFF timer value:
1. Turn the light ON.
2. Tap the [Teach] button on the sensor three times to edit the timer period, or to set it to
zero seconds. The light ramps up to full ON and then dims to OFF to acknowledge the
input.
Taps Occupancy Sensor Timer Light Response
3 taps 0 seconds 1 blink

6 Tri-Zone Dimming Controller Configuration Guide
3. Set a number of minutes for the timer period. Tap the [Teach] button the number of times
indicated in the table below to set the timer period. The light responds a number of times
to confirm the change and then returns to normal operation.
Taps Occupancy Sensor Timer Light Response
1 tap 5 minutes 2 blinks
2 taps 10 minutes 3 blinks
3 taps 15 minutes 4 blinks
4 taps 20 minutes 5 blinks
5 taps 25 minutes 6 blinks
Save State
The controller saves its current operating state every ten minutes so when power is cycled, it
returns to the last saved values. The save state function can be overridden with a value used to
recall a particular dimming output value after a power cycle. Garibaldi Pro software is required
to configure overrides.
Grace Timer
The occupancy sensor grace timer is a short period of time during which the controller returns
the lights to the previous occupied state if triggered by motion, or audio in the case of Dual
Tech sensors. The grace timer starts counting down after the occupancy auto-OFF timer has
expired, providing a time period for an undetected occupant to signal that the space is
occupied. Garibaldi Pro software is required to configure the grace timer. The default is 30
seconds.
Dual Technology Occupancy Sensors
Dual Tech sensors have built-in occupancy timers that manage the transition from occupied to
vacant state. To allow the Dual Tech sensor to control the vacancy action, the controller’s
occupancy sensor auto-OFF timer parameter should be set to 0 seconds. See Occupancy Sensor
Auto-OFFTimer on the previous page.
Occupancy Sensors and Partial-ON
If only occupancy sensors are linked to the controller, the sensors automate the lights both ON
and OFF. The dimming output for ON adjusts to the occupancy partial-ON value. The default
value is 100%. It can be changed using Simple Tap.
To set the partial-ON value and enable/disable automatic partial-ON:
1. Use a linked switch with the light ON and dim to the target partial-ON value.
2. Press the [Teach] button on the sensor, and then do one of the following:
•
Press the switch ON four times to enable partial-ON.
•
Press the switch ON three times followed by one OFF to disable partial-ON.
Occupancy Sensors and Partial-OFF
If the application requires the lights to remain ON during vacant periods but at a dimmed level,
set the vacancy partial-OFF value using Simple Tap. The default value is 20%.
