Installation
All local codes and standard electrical practices should be observed. Ensure
that the junction box is clean and free of obstructions and that all wiring is
installed correctly.
Install the Controller
Mount the controller directly to the exterior of the junction box or panel
either at the electrical load or before the load in the circuit.
Review these instructions completely before installing the controller.
1. Locate the circuit breaker panel and terminate power to the circuit.
2. Remove the cover plate and other hardware from the junction box to
access the wiring.
3. Mount the controller.
4. Refer to the wiring diagram to connect the controller to line power,
neutral, and load wires. Use wire nuts on all connections and
individually cap any bare wires, except the orange antenna wire.
5. Connect the gray and the striped violet/red wires to the driver or
ballast’s dimming interface. Connect the striped violet/green 0-10 V
analog color control output wire to the tunable white input on the LED
driver.
6. Replace the electrical box cover plate.
7. Restore power to the circuit.
Note:
Follow applicable NEC and local electrical code
requirements when installing and powering the
controller.
Note:
The Micro USB port is for factory use only. Do not attach
cables or accessories to this port.

Electrical Terminations
Power to the controller is connected between the White (Neutral) and the
Black Line power: ELED2 (120-277 VAC) or ELED2H (240–347 VAC). The
Class 1 power limited dimming lines (violet with red stripe wires) is used to
provide 0–10 V intensity control of a dimming ballast or LED driver. The
orange wire is an antenna. Do not cut, cap or connect this wire. Use only UL
approved wire when making connections to the controller (see table below).

Controller Interface
The controller interface has two tricolor LEDs and two buttons.
Tricolor LEDs
The Power and Learn LEDs can display red, green, or blue. LED color and
combinations indicate which of the three channels is providing information
via blink codes or is in an operational mode. See Blink Codes and
Operations on page 7.
• Red - Channel 1 - dimming output.
• Green - Channel 2 - tunable white output.
• Blue - Channel 3 - external setpoint input.
Learn Button
The [Learn] button initiates Link mode for linking switches or sensors in
each of the controller’s channels. See the relevant switch or sensor
documentation for information on linking. Link mode times out after 30
seconds of inactivity.
Repeating the linking process for a device that is already linked to a
controller will unlink it from that controller.
Clear Button
The [Clear] button resets the controller either to its pre-commissioned state
or to its factory default state.
To reset to pre-commissioned state:
1. Press the [Clear] button until the Power and Learn LEDs start blinking.
2. Release the [Clear] button. The LEDs repeat a blink code by color to
indicate the type and number of devices linked to each channel at pre-
commissioning.
To reset to factory default state:
1. Press and hold the [Clear] button until the Power and Learn LEDs start
blinking. Continue to hold for 15 seconds until the LEDs turn solid.
2. Release the [Clear] button. The Power LED displays solid red to indicate
factory default state. All links are removed.
Test the Controller
Echoflex provides the controller in either a pre-commissioned state or a
factory default state.
• Pre-commissioned devices are linked, configured, and labelled
according to customer specifications. When powered up, the LEDs
repeat a blink code by color to indicate the type and number of
devices currently linked to each channel. See Blink Codes and

Echoflex Installation Guide
Tunable White Dimming Controller
Tunable White Dimming Controller Page 7 of 8 Echoflex
Operations on page 7. To test the relay(s), press the [Learn] button
or use a linked switch.
• In factory default state, when powered up, the Power LED displays
solid red to indicate the controller has no linked devices. To test the
relay(s), press the [Learn] button or link a switch. See relevant switch
documentation.
A maximum of 20 switches or sensors can be linked to one controller.
