Installation & Operation Guide
Description
The Crestron® CLW-DELVEX-E and CLW-DELVEX-P are Cameo® in-wall ELV dimmers
designed for dimming electronic low-voltage lighting, supporting lighting loads such as
tungsten-halogen, incandescent, and dimmable LED replacement lamps. Versatile and
affordable, the CLW-DELVEX-E and CLW-DELVEX-P feature eld-replaceable, engravable
buttons and can be congured with various button layouts and designer colors.
The CLW-DELVEX-E and CLW-DELVEX-P are functionally identical. For simplicity within
this guide, the term “CLW-DELVEX-E/P” is used except where noted.

Important Notes
WARNING: To avoid re, shock, or death, turn off power at the circuit breaker or fuse
and test that power is off before wiring!
WARNING: New installations should be checked for short-circuits prior to installing a
CLW-DELVEX-E/P dimmer. With the power off, close the circuit and then restore power.
If the lights do not work, or a breaker trips, check and correct the wiring or xture (if
necessary). Install the dimmer only when the short is no longer present. The warranty is
void if the dimmer is installed and operated with a shorted load.
CAUTION: TO REDUCE THE RISK OF OVERHEATING AND POSSIBLE DAMAGE TO
OTHER EQUIPMENT, DO NOT INSTALL TO CONTROL A RECEPTACLE, A MOTOROPERATED APPLIANCE OR A TRANSFORMER-SUPPLIED APPLIANCE.
ATTENTION: GRADATEURS COMMANDANT UN BALLAST-AFIN DE RÉDUIRE LE
RISQUE DE SURCHAUFFE ET LA POSSIBILITÉ D’ENDOMMAGEMENT À D’AUTRES
MATÉRIELS, NE PAS INSTALLER POUR COMMANDER UNE PRISE, UN APPAREIL
OPÉRÉ DE MOTEUR OU UN APPAREIL ALIMENTÉ PAR UN TRANSFORMATEUR.
NOTE: Observe the following points.
• Codes: Install in accordance with all local and national electrical codes.
• Installation: This product should be installed by a qualied electrician.
• Wiring: Use copper wire only. For supply connections, use wire rated for at least
75 °C.
• Lamp Type: For use with permanently installed incandescent, electronic
low-voltage halogen or LED, tungsten-halogen, or dimmable CFL only.
• Temperature: For use where temperatures are between 32° to 104 °F (0° to 40 °C).
• Electrical Boxes: Devices mount in standard electrical boxes. For easy installation,
Crestron recommends using 3-1/2 in (89 mm) deep electrical boxes. Several
devices can be installed in one electrical box (multigang). This requires derating of
the dimming device. For a smooth appearance, one-piece multigang faceplates
(not included) can be installed.
• Switches: Mechanical 3- or 4-way switches do not work with CLW-DELVEX-E/P
dimmers.
• Spacing: If mounting one device above another, leave at least 4-1/2 in (115 mm)
vertical space between them.
• Low-Voltage Applications: Use with electronic low-voltage transformers only.
• Do not use any magnetic low-voltage transformers.
• 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 to prevent transformer
failure due to overcurrent.

Multigang Installations
In multigang installations, several devices are grouped horizontally in one electrical box.
For a smooth appearance, one-piece multigang faceplates (not included) can be installed.
NOTE: When installing into a multigang box, do not fully tighten devices to the box
until the faceplate has been aligned.
The load capacity for each device in the electrical box must be derated. Derating
information is shown in the illustration below.
Derating Information for CLW-DELVEX-E/P Dimmers
Operation
NOTE: Before using the CLW-DELVEX-E/P, ensure the device is using the
latest rmware. Check for the latest rmware for the CLW-DELVEX-E/P at
www.crestron.com/rmware. Load the rmware onto the device using Crestron
Toolbox™ software.
NOTE: The device may be warm during operation. This is normal.
Basic Operation
The CLW-DELVEX-E/P is shipped with a rocker switch already installed. In this
conguration, the unit functions as shown below.
NOTE: Operation described in this guide assumes the CLW-DELVEX-E/P is operating
in Local mode (without the use of a control system). The device can also operate in
Remote mode, in which button behavior is dictated entirely by the control system
program.
The LEDs indicate
the load level.
When all loads are
off, the top LED

NOTE: If the dimmer remains powered after the air-gap is opened, the HOT and DIM
terminals have been connected in reverse. Turn off power at the circuit breaker or fuse
and adjust the connections.
NOTE: Power to the load is automatically disconnected when the button assembly
is removed. For instructions on removing the button assembly, refer to “Changing the
Button Assemblies.”
Setting Preset Levels
The CLW-DELVEX-E/P can recall and store up to three presets depending on the installed
button conguration.
Set a preset level.
1. Adjust the light level to the desired level.
2. Enter Programming mode by quickly pressing the program button as shown below.
Buttons that are capable of storing a preset will ash their LEDs.
NOTE: Programming mode is disabled when the load is off.
3. Press and hold the desired preset button until the LED blinks (approximately two
seconds). Release the button to store the new level.
4. If a button is not pressed, the device exits Programming mode after approximately
ve seconds.

Wireless Communications
The device connects to the Crestron network via the inNET EX® communications protocol.
Use the procedures outlined below to join or leave an inNET EX network and to verify
communications between the device and the control system.
Joining an inNET EX Network
Before a device can be used in a lighting system, it must rst join an inNET EX network by
being acquired by an inNET EX gateway.
NOTE: A device can be acquired by only one gateway.
1. Put the inNET EX gateway into Acquire mode from the unit itself or from Crestron
Toolbox, as described in its manual at www.crestron.com/manuals.
NOTE: In an environment where multiple gateways are installed, only one gateway
should be in Acquire mode at any time.
2. Place the device into Acquire mode.
a. Tap the top button three times, and then press and hold it down (tap-tap-tap-
press+hold) until the top LEDs on the device ash once (this can take up to 10
seconds).
b. Release the button to start the acquire process. The top LED ashes slowly to
show that the device is actively scanning the inNET EX network.
• The top two LEDs turn on for 5 seconds to show that the device has been
successfully acquired to the inNET EX network.
• The top LED ashes quickly to indicate that the device was not successfully
acquired by the inNET EX network. Press the top button to acknowledge failure
to acquire the inNET EX network. Ensure the gateway is in Acquire mode and
within range before attempting the acquire process again.
3. Once all devices have been acquired, take the gateway out of Acquire mode. Refer to
the gateway’s manual for details.
Leaving an inNET EX Network
To leave an inNET EX network, put the device into Acquire mode, as described in “Joining
an inNET EX Network” above, when no gateway is in Acquire mode.
Verifying Communications Status
To check the communications status of the device, tap the top button three times and then
press and hold it down (tap-tap-tap-press+hold) for up to 2 seconds. The LED ashes to
indicate the communications status. Refer to the following table for details.
LED COMMUNICATIONS STATUS
Turns on for 5 seconds The device is communicating with the control system.
Flashes three times The device is not communicating with the gateway, but the
gateway is not communicating with the control system.
Flashes twice The device was previously joined to the network but is not
communicating with the gateway.
Flashes once The device is not joined to the network.
