In-Wall 0—10 V Dimmer, 230 Vac
Installation Guide

Description

The CLWI-DIMFLVEX delivers native Crestron

®

 control to 0—10 V dimmable fixtures or 

switched loads in new or retrofit 230 volt applications. Featuring reliable infiNET 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 fixtures from a single gang, without requiring external boosters.

Important Notes

WARNING:

  To avoid fire, 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 flow 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 fluorescent 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 flat-head screwdriver to tighten the connections.

WARNING:

  To avoid fire, 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.

Configuration

The local buttons must be defined 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.

Define the Local Buttons

Buttons that are identified as local buttons have predefined functions that are described in 
the “Default Button Functions” section. 

NOTE:

  Buttons that are not identified as local buttons must be controlled by a control 

system.

Define 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 flash 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 configured, 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 flash, 

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 flashing. The connected load dims to 50%.

NOTE:

  During Min/Max Dimming mode the device LEDs flash 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 flash, 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 flicker, 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 
configuration and local programming. Buttons that utilize presets are identified 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 flash their LEDs.

3.  Press and hold the desired preset button for about 2 seconds. The LED flashes.

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 configuration determined in the “Define Local Buttons” procedure.
The illustrations that follow show various button assembly configurations and the default 
button press functions. The circled button numbers identify buttons that are configured for 
local operation. All other button functions are determined by control system programming.
The button functions for the CLWI-DIMFLVEX are shown below.
