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).
