CLWI-DIMFLVEX
In-Wall 0—10 V Dimmer, 230 Vac
Installation Guide
Description
The CLWI-DIMFLVEX delivers native Crestron®control to 0—10 V dimmable xtures or
switched loads in new or retrot 230 volt applications. Featuring reliable inNET EX®
wireless technology, the CLWI-DIMFLVEX can be installed in virtually any location thanks
to reliable mesh networking. The CLWI-DIMFLVEX delivers a perfect solution for controlling
newer LED xtures from a single gang, without requiring external boosters.

Important Notes
WARNING: To avoid re, shock, or death, turn off the power at the circuit breaker or
fuse and test that the power is off before wiring!
CAUTION: TO REDUCE THE RISK OF OVERHEATING AND POSSIBLE DAMAGE
TO OTHER EQUIPMENT, DO NOT INSTALL TO CONTROL A RECEPTACLE OR A
TRANSFORMER-SUPPLIED APPLIANCE.
CAUTION: When wiring, refer to the following cautions.
• Install on 10 A branch circuits only.
• Install with 1 x 1.5—2.5 mm² wire complying with BS6004:2000/IEC 60245 and
local electrical codes.
• Use with loads that have a power factor greater than 0.95.
NOTE: LOW-VOLTAGE APPLICATIONS: Operation of a low-voltage circuit with all
lamps inoperative or removed may result in current ow in excess of normal levels. To
avoid transformer overheating and premature transformer failure, Crestron recommends
the following:
• Do not operate low-voltage circuits without operative lamps in place.
• Replace burned-out lamps as quickly as possible.
• Use transformers that incorporate thermal protection or fuse transformer primary
windings to prevent transformer failure due to overcurrent.
NOTE: When wiring, refer to the following notes.
• A neutral connection is required for this device to operate.
• Use copper wire only. For supply connections, use wires rated for at least 75 °C.
• Use only with permanently installed 0—10 volt uorescent ballast or LED driver
(4-wire).
• For use where temperatures are between 0° to 40 °C (32° to 104 °F).
WIRING
Make the power connections to the CLWI-DIMFLVEX. Use 1 x 1.5—2.5 mm2 (14—12 AWG)
wiring when making connections. When making connections, insert the wires into the back
of the unit and use a small at-head screwdriver to tighten the connections.
WARNING: To avoid re, shock, or death, turn off the power at the circuit breaker or
fuse and test that the power is off before wiring!
Tighten the screws
with a small flat-head
screwdriver.

Conguration
The local buttons must be dened when using the CLWI-DIMFLVEX in Local mode
(operating without a control system). The minimum and maximum dimming levels and the
preset dimming levels can be established.
Dene the Local Buttons
Buttons that are identied as local buttons have predened functions that are described in
the “Default Button Functions” section.
NOTE: Buttons that are not identied as local buttons must be controlled by a control
system.
Dene the local buttons.
1. Press and hold the setup button (located in the lower right corner of the device) for
5 seconds to enter Button Layout mode. The LEDs that correspond to the current
button layout begin to ash quickly. Do not release the setup button.
NOTE: If the setup button is held for 15 seconds without other button presses, the
device restarts. Refer to “Device Reboot” for additional information.
NOTE: If the setup button is released before all buttons are congured, the device
exits Button Layout mode and no changes are saved. The device reverts to the
previously programmed button layout.
2. While holding the setup button, and within 5 seconds of the LEDs starting to ash,
press all of the buttons on the device that require local functionality. Refer to the
“Default Button Functions” section for valid local button options. The LED illuminates
to verify the button press.
NOTE: The device exits Button Layout mode after 10 seconds pass without
additional button assignments. The device reverts to its previously programmed
button layout.
3. Release the setup button.
NOTE: If an invalid button pattern is selected, the button pattern is not saved.
Setting the Minimum and Maximum Dimming Levels
Establish the minimum and maximum dimming levels for the connected loads. To enter
Min/Max Dimming mode:
1. Press and hold the setup button for 10 seconds until all LEDs light and the middle
LEDs begin ashing. The connected load dims to 50%.
NOTE: During Min/Max Dimming mode the device LEDs ash quickly and indicate
the current minimum and maximum dimming levels.
NOTE: The maximum level is saved only if the light level is raised above 75%
(either of the top two LEDs are illuminated).
NOTE: The minimum level is saved only if the light level is lowered below 45%
(either of the bottom two LEDs are illuminated).
2. Press any top button on the dimmer to raise the load to the maximum desired level. If
the connected load begins to cycle or ash, the level must be reduced.
3. Press and hold the setup button for 2 seconds to save the maximum dim level.
4. Press any bottom button on the dimmer to lower the load to the minimum desired
level. If the connected load begins to icker, the level must be increased.
5. Press and hold the setup button for 2 seconds to save the minimum dimming level.
6. Tap the setup button to exit Min/Max Dimming mode.
Setting Preset Levels
The device can recall and store up to three presets, depending on the installed button
conguration and local programming. Buttons that utilize presets are identied in the
“Default Button Functions” section. To set the preset levels, follow the procedure below:
1. Adjust the light level to the desired level.
2. Press the setup button to enter Programming mode. Buttons capable of storing
presets ash their LEDs.
3. Press and hold the desired preset button for about 2 seconds. The LED ashes.
NOTE: If a button is not pressed, the device exits Programming mode after about
5 seconds.
Default Button Functions
The default functionality of a button depends on the button assembly that is installed and
the button conguration determined in the “Dene Local Buttons” procedure.
The illustrations that follow show various button assembly congurations and the default
button press functions. The circled button numbers identify buttons that are congured for
local operation. All other button functions are determined by control system programming.
The button functions for the CLWI-DIMFLVEX are shown below.
