Remote in Multi-Location Applications
INSTALLATION INSTRUCTIONS
WARNINGS AND CAUTIONS:
• To be installed and/or used in accordance with appropriate electrical codes and regulations.
• If you are unsure about any part of these instructions, consult a qualifi ed electrician.
• To avoid overheating and possible damage to this device and other equipment, do not install to
control a receptacle, fl uorescent lighting, a motor- or a transformer-operated appliance.
• Use with magnetic low-voltage transformers, incandescent, or 120V halogen fi xtures only. Use a Leviton
electronic low-voltage dimmer to control electronic (solid state) low-voltage transformers.
• Total minimum load must exceed 40W or 40VA.
WARNINGS AND CAUTIONS:
• When a magnetic low-voltage circuit is operated at a dim level, with all lamps inoperative, excess current
may fl ow through the transformer. To avoid possible transformer failure due to overcurrent, use a
transformer that incorporates thermal protection or a fuse at the primary windings.
• Use only one (1) dimmer per load. For remote operation, use Leviton Remote, Cat. No. TTØØR-1.
Do not use a 3-way switch.
• Disconnect power at circuit breaker or fuse when servicing fi xture.
• Use this device only with copper or copper clad wire. With aluminum wire use only devices marked
CO/ALR
or
CU/AL.
Tools needed to install your Dimmer:
Slotted/Phillips Screwdriver
Electrical Tape
Pliers
Pencil
Cutters
Ruler
Changing the color of your Dimmer:
Your Dimmer includes two color options. The Dimmer ships with the
White frame attached. To change color of frame, proceed as follows:
When installing more than one dimmer in the same location, the side
sections of the mounting strap must be removed. Use pliers to carefully
bend side sections back and forth until they break off. The side sections
dissipate heat, so removing them requires a derating of the dimmer’s
capacity
(refer to chart).
Installing Dimmer by itself or with other devices:
If installing Dimmer in a single device application, proceed with the
INSTALLING YOUR DIMMER
section. If installing Dimmer in a multi-
device application, proceed as follows:
MULTI-DEVICE APPLICATION:
NOTE:
You only need to remove side sections if installing with other
dimmers or if it does not fi t in wall box – not when installing with
mechanical switches.
Single-Pole:
Look at the back of your switch.
If there are 2 wires connected
to two screw terminals (not
including a green or bare copper
wire used for grounding), you
have a Single-Pole switch.
3-Way:
Look at the back of your switch.
If there are 3 wires connected
to three screw terminals (not
including a green or bare copper
wire used for grounding), you
have a 3-Way switch.
DO NOT
add a single-pole switch in this
location.

NOTE:
Use check boxes when Steps are completed.
WARNING:
To avoid fi re, shock, or death;
TURN OFF
POWER
at circuit breaker or fuse and test that power is off
before wiring!

Tag Common Screw Wire
(screw is usually black and/or
marked "common")
Remove all
inner side
sections
Do not
remove
outer
side
sections
Removing existing switch:
Remove existing
wallplate and switch mounting screws. Carefully pull switch
from wall box. DO NOT remove wires attached to the switch
at this time.
Identifying your wiring application (most common):
NOTE:
If the wiring in the wall box does not resemble any of
these confi gurations, consult a qualifi ed electrician.
Step 2
Step 3
Disconnecting switch wires and preparing wires:
• Disconnect wires from screw terminals or
Quickwire™ slots (shown).
• Pull off pre-cut insulation from Dimmer leads.
• Make sure that the ends of the wires from the
wall box are
straight (cut if necessary).
• Remove 5/8" (1.6 cm) of insulation from each
wire in the wall box (shown).
•
For Single-Pole Application, go to Step 5a.
• For 3-Way Application, go to Step 5b.

MAXIMUM BULB WATTAGE:
Low-voltage dimmers are rated in Volt-Amps (VA). The maximum bulb
wattage is determined by the effi ciency of the transformer in the low-
voltage lighting system. Transformer effi ciencies will vary from different
manufacturers; consider 75% effi cient as average. Use the chart to
determine maximum bulb wattage for typical transformer effi ciency ratings.
