Crestron CLW-SLVD Operating Manual

CLW-DIM, DIMS, & SLVD(W/A/B)

Introduction

Features and Functions

The CLW-DIM (-DIM) is a stand-alone wall box dimmer
that can also act as a Cresnet
Crestron® control processor. The CLW-DIM has four
preset lighting levels that can be adjusted (refer to note
below). The CLW-DIM also includes two isolated, non­polarized Cresnet wires (plus a ground wire) for
connecting to the Cresnet network over a twisted pair
wire with shield.

NOTE: The four preset levels are noted as Button
1-High, Button 1-Low, Button Preset 2, and Button Preset

3. Preset “Button 1-High” is usually used for turning
lights on to full brightness while preset “Button 1-Low” is
usually used for turning the lights off. Although “1-High”
and “1-Low” are usually used for “On” and “Off”
respectively, the light level for each preset can be
customized by the user. Refer to “Operating Buttons and
Switches” on page 5 for more information on customizing
light levels.

The CLW-DIM features a three-position mode selection
switch. Refer to “Operating Buttons and Switches” on
page 5 for more information. In the absence of Cresnet
communications, the dimmer can still be used to control
lighting.

The CLW-DIMS (-DIMS) is similar to the -DIM with the
added capability of working with a slave unit
(CLW-SLVD) in a multi-switch / single circuit
application.

The CLW-SLVD (-SLVD) is a slave unit that when used
in conjunction with the -DIMS acts as an additional
dimmer control point in a multi-dimmer / single circuit
application. It does not connect to a Cresnet system and
cannot be used without a -DIMS. The -SLVD does not
have a mode selection switch and is not programmable. It
emulates the operation of the -DIMS to which it is
connected.

These dimmers are available in a variety of colors and
textures. The table below shows the availability.

Physical Description

The -DIM and -DIMS contain three buttons (one large,
two small), a light emitting diode (LED), and a three­position slider-switch, shown after this paragraph. The

-SLVD is similar to the -DIM and -DIMS but does not
have the slider-switch. Line voltage connections are made
at the rear of the dimmer. Three Class 2 low voltage
wires, located on the front of the switch provide a Cresnet
connection to a control system. The wires are routed to
the bottom of the unit for placement outside of the wall
box.

requirements by Underwriters Laboratories Inc.

Important Notes

Read before installation.

• Codes: Install in accordance with all local and
national electrical codes.

Alternate wiring methods may be used for the
Class 2 wiring connection. The 2002 National
Electrical Code (Article 725-55) prohibits Class
2 conductors of the -DIM, -DIMS, and -SLVD to
occupy the same outlet box as the power
conductors. The exception is Part D of Section

725.55 of the 2002 National Electrical Code,
which allows a device’s power conductors to be
installed near (0.25 inch minimum spacing)
associated Class 2 conductors in the same outlet
box. Consult the 2002 National Electrical Code
Handbook and your local electrical inspector
before proceeding.

Do not use the supplied butt-splice connectors if
the Class 2 conductors are to be installed in the
wallbox with the power conductors. Use

approved connectors (supplied by others) to
make Class 2 connections inside the wallbox.

•

CAUTION: TO REDUCE THE RISK OF

OVERHEATING AND POSSIBLE DAMAGE
TO OTHER EQUIPMENT, DO NOT INSTALL
TO CONTROL A RECEPTACLE OR A
MOTOR OPERATED APPLIANCE (i.e. BATH
FAN).

• Wiring: Use copper wire only. For supply
connections, use wires rated for at least 75°C.

• Lamp Type: The -DIM, -DIMS, and -SLVD are
designed for use with permanently installed
incandescent, magnetic low voltage, or tungsten­halogen only.

• Temperature: The -DIM, -DIMS, and -SLVD are
designed to be used where temperatures are
between 32° to 104°F (0° to 40°C).

• Wallboxes: Devices mount in standard
wallboxes. For easy installation, Crestron
recommends using 3 ½” deep wallboxes. Several
devices can be installed in one wall box
(multigang). This requires the removal of side
sections (refer to diagram on page 3) and the
derating of the dimming device. For a smooth
appearance, one-piece multigang faceplates (not
supplied) can be installed.

• Other Switch Devices: Mechanical 3- or 4-way
switches will not work with the -DIM, -DIMS, or

-SLVD.

• Spacing: If mounting one device above another,
leave at least 4 ½” vertical space between them.

• Low Voltage Applications: Use with core and
coil (magnetic) low voltage transformers only.
Do not use any solid-state electronic low voltage
transformers.

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.

Multigang Installations

In multigang installations, several controls are grouped
horizontally in one wallbox. For a smooth appearance,
one-piece multigang faceplates (not supplied) can be
installed.

1. When combining controls in a wallbox, remove
inner side sections prior to wiring (refer to the
following figure).

Operating Buttons and Switches

The -DIM, -DIMS, and -SLVD feature three pushbuttons
(one large, and two-small). The -DIM and -DIMS also
have a three-position mode selection switch. The function
of each button is determined by the position of the mode
selection switch. Refer to the following diagram.

NOTE: The -SLVD does not have a mode selection
switch. It will act in the same mode as the -DIMS.

Buttons of CLW-DIM, -DIMS, and -SLVD

Button 1

Button 2

OFF

When the mode selection switch is in the “OFF” position,
the buttons will not have any function and the load is
disconnected from the power source. This must be used
when changing light bulbs to ensure that the load is fully
disconnected from power.

ADJ

When the mode selection switch is in the “ADJ” position,
the large button is used to switch between the “Button
1-High” and “Button 1-Low” presets (typically “On” and
“Off”). The lighting level can be manually adjusted using
the two small buttons to raise (right button) and lower
(left button) the lighting level.

If the lighting level is to be stored as a preset, move the
mode selection switch to the PRE position. Press and hold
the desired preset button until the LED flashes.

5. Splice the gray wires of the -DIM or -DIMS to
the Class 2 low voltage wires connected to the
Crestron control system, a Crestron power
supply, a Crestron C2N-NPA8, or a Crestron
connection block device. Push the wires and the
splices into a hole in the drywall to provide the
necessary separation.

6. Push all Class 1 power wires back into the
wallbox and fasten the device to the wallbox
with the provided screws.

7. Attach decorative faceplate.

8. Restore power.

PRE

NOTE: Before storing a preset, the lighting must be
adjusted to the desired level while in the ADJ mode.

When the switch is in the PRE position, it is in the preset
mode and can be used to recall and/or store preset lighting
levels. The large button is used to recall and/or store the
“Button 1-High” and “Button 1-Low” presets. The lower
left button (button 2) is used to recall and/or store preset
level two. The lower right button (button 3) is used to
recall and/or store preset level three. Pressing and
releasing a button will fade to the preset lighting level
over a three second period. Tapping a button while the
light is fading will cause the light level to “jump” to the
preset without fading. Pressing and holding a button until
the LED flashes will store the current lighting level.

Installation Guide – DOC. 5995C Stand Alone Wall Box Dimmer: CLW-DIM, DIMS, & SLVD • 5

CLW-DIM, DIMS, & SLVD(W/A/B)

To store preset values for “Button 1-High” and “Button
1-Low”; While in the PRE mode, recall the lighting level
to be changed. (For example, if default preset values are
to be changed, turn the light to maximum brightness or
turn off the lights by tapping the large button). Switch to
the ADJ mode and adjust the lighting to the desired level.
Move the mode selection switch to PRE. Press and hold
the large button until the LED flashes to store the new
preset value.

NOTE: If a new preset value for “Button 1-High” is
lower than the stored value for “Button 1-Low”, the
previously stored value for “Button 1-Low” becomes
“Button 1-High”. Similarly, if a new preset value for
“Button 1-low” is higher than the value stored for “Button
1-High”, the previously stored value for “Button 1-High”
becomes “Button 1-Low”.

NOTE: The default preset light values for each button
are:

• Button 1-High: 100%

• Button 1-Low: 0%

• Button Preset 2: 30%

• Button Preset 3: 70%

NOTE: The device may be warm to the touch during
operation. This is normal.
