Crestron CLW-DIM1, CLW-DIMS1 User Manual

CLW-DIM1, DIMS1, & SLVD1(W/A/B)

Introduction

Features and Functions

The CLW-DIM1 (-DIM1) is a stand-alone wall box
dimmer that can also act as a Cresnet
to a Crestron® control processor. The CLW-DIM1 has
two preset lighting levels that can be adjusted (refer to
note below). The CLW-DIM1 also includes two isolated,
non-polarized Cresnet wires (plus a ground wire) for
connecting to the Cresnet network over a twisted pair
wire with shield.

NOTE: The two preset levels are noted as Preset 1-High
and Preset 1- Low. “Preset 1-High” is usually used for
turning lights on to full brightness while preset “Preset 1­Low” is usually used for turning the lights off. Although
“Preset 1-High” and “Preset 1-Low” are usually used for
“On” and “Off” respectively, the light level for each
preset can be customized by the user. Refer to
“Operation” on page 6 for more information on
customizing light levels.

The CLW-DIM1 features a three-position mode selection
switch. Refer to “Operation” on page 6 for more
information. In the absence of Cresnet communications,
the dimmer can still be used to control lighting.

The CLW-DIMS1 (-DIMS1) is similar to the -DIM1 with
the added capability of working with a slave unit
(CLW-SLVD1) in a multi-dimmer / single circuit
application.

The CLW-SLVD1 (-SLVD1) is a slave unit that when
used in conjunction with the -DIMS1 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 -DIMS1. The -SLVD1 does not
have a mode selection switch and is not programmable. It
emulates the operation of the -DIMS1 to which it is
connected unless the mode selection switch of the master
is set to “OFF”.

These dimmers are available in white, almond, and black.
White units are designated by part numbers ending in
“W”. Almond units are designated by part numbers
ending in “A”. Black units are designated by part numbers
ending in “B”. Each dimmer can be covered with a
decorative faceplate (not supplied).

CLW-DIM1, DIMS1, & SLVD1(W/A/B)

Physical Description

The -DIM1 and -DIMS1 contain one large pushbutton, a
light emitting diode (LED) with software adjustable
brightness*, and a three-position slider-switch, shown
after this paragraph. Line voltage connections are made at
the rear of the dimmer. Three Class 2 low voltage wires,
located on the front of the dimmer, provide a Cresnet
connection to a control system. The wires can be routed to
the bottom of the unit for placement outside of the wall
box. The -SLVD1 is similar to the -DIM1 and -DIMS1
but does not have the slider-switch or the Class 2 low
voltage wires.

* LED brightness can only be adjusted through Crestron programming

software.

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 -DIM1, -DIMS1, and

-SLVD1 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

connections, use wires rated for at least 75°C.

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 4) 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 -DIM1, -DIMS1,
or -SLVD1.

• 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).

• Lamp Type: The -DIM1, -DIMS1, and -SLVD1
are designed for use with permanently installed
incandescent, magnetic low voltage, or tungsten­halogen only.

• Temperature: The -DIM1, -DIMS1, and -SLVD1
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

NOTE: Crestron recommends using Cresnet-DM cable
for connecting the -DIM1 and -DIMS1 to the Cresnet
network.

Installation

WARNING: Turn off power at the circuit breaker.
Installing with power on can result in serious personal
injury and damage to the device.

NOTE: The -DIM1, -DIMS1, and -SLVD1 require a
neutral wire for operation. If no neutral is present, contact
a licensed electrician for installation or refer to the
alternative wiring diagrams described in “Appendix:
Wiring Diagrams” on page 8.

NOTE: The -DIMS1 must be installed in the same
wallbox that contains the connections to the load.

2. To remove a side section, bend the side section
back and forth with a pair of pliers until the
section breaks off from the mounting plate. Use a
file or sandpaper to remove any excess metal.

NOTE: New installations should be checked for short
circuits prior to installing the -DIM1, -DIMS1, or

-SLVD1. With power off, close the circuit and restore
power. If the lights do not work or a breaker trips, check
and correct the wiring or fixture (if necessary). Install the

Prewire for Master Application

Each device has two Class 2 low voltage wires (plus a
ground wire) that provide a Cresnet connection over
shielded twisted-pair to a Crestron control system. These
wires are routed to the bottom of the device for
connection outside of the wallbox. The low voltage wires
are pulled from each device location to the Crestron
control system or a Crestron connection block device. Use

-DIM1, -DIMS1, or -SLVD1 only when the short is no
longer present. The warranty is void if the -DIM1,

-DIMS1, or -SLVD1 is installed and operated with a
shorted load.

When installing a -DIM1 or a -DIMS1 without a slave,
follow the instructions in “Wiring a -DIM(S)1 (No
Slaves)”. If wiring a -DIMS1 with a -SLVD1, refer to

#22 AWG, twisted, shielded, 2-conductor wire. Wiring
