3-Way Wiring with DD0SR-10 Coordinating Remote 
(no LED) Application:
Preparing and connecting wires:
This switch can be wired using side wire terminal screws or 
through backwire openings. Choose appropriate wire stripping 
specifications accordingly.
WARNING: TO AVOID FIRE SHOCK OR DEATH; TURN 
OFF POWER at circuit breaker or fuse and test that power is off 
before wiring!

The next generation of lighting control technology is here with 
the new Decora
®
 Digital Switch with Bluetooth
®
 Technology. This 
innovative device works using the Leviton Decora
®
 Digital Dimmer & 
Timer app that can be easily downloaded to smartphones or tablets 
and paired to the Leviton Switch using Bluetooth
®
 technology. 
Decora
®
 Digital Devices give users point-to-point local control to 
automate lighting, bridging the gap between standard switches and 
whole-house automation systems.
Enjoy the combined functions of a standard wall switch and 
a countdown or programmable timer switch in one attractive 
device. Use of the app allows greater flexibility for accurate timer 
functionality and makes pushing buttons for timed events a tedious 
chore of the past.
The Leviton Decora
®
 Digital Dimmer & Timer app can be easily 
downloaded to mobile devices and is compatible with Android and 
iOS smartphones or tablets. The app is easy to use with simple, 
intuitive on-screen menu options to independently control Decora
®
Digital dimmers and switches throughout the home.
Decora
®
 Digital Devices are ideal for living rooms, bedrooms, 
kitchens, dining rooms, home offices, outdoor lighting or anywhere 
full control of lighting is desired.

NOTE: The switch must be installed in a wall box that has a Line 
Hot connection. The coordinating remote must be installed in a wall 
box with a Load connection and a Neutral connection. A Neutral 
wire to the coordinating remote needs to be added as shown. If 
you are unsure about any part of these instructions, consult an 
electrician.
NOTE: Maximum wire length from switch to all installed remotes 
cannot exceed 300 ft (90 m).
WIRING SWITCH (wall box with line hot connection):
Connect wires per WIRING DIAGRAM as follows:
•  Green or bare copper wire in wall box to Green terminal screw.
•  Line Hot (common) wall box wire identified (tagged) when 
removing old switch to terminal screw marked "BK".
•  First Traveler wall box wire to terminal screw marked "RD" 
(note wire color).
•  Remove Red insulating label from terminal screw marked 
"YL/RD".
•  Second Traveler wall box wire to terminal screw marked 
"YL/RD" (note wire color). This traveler from the switch must go 
to the terminal screw on the remote marked "YL/RD".
•  Line Neutral wall box wire to terminal screw marked "WH".
WIRING COORDINATING REMOTE (wall box with load 
connection):
Connect wires per WIRING DIAGRAM as follows:
NOTE: "BK" and "RD" terminals on coordinating remote are 
unused. Tighten both screws.
•  Green or bare copper wire in wall box to Green terminal screw.
•  Load wall box wire identified (tagged) when removing old switch 
to First Traveler (note color as above).
•  Second Traveler wall box wire (note color as above) to terminal 
screw marked "YL/RD". This traveler from the remote must go to 
the terminal screw on the switch marked "YL/RD".
•  Remove White insulating label from terminal screw marked 
"WH".
•  Line Neutral wall box wire to terminal screw marked "WH".
•  Proceed to Step 5.
WARNINGS AND CAUTIONS
•  TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF POWER at circuit breaker or fuse and test that power is off before wiring!
• 
TO AVOID FIRE, PERSONAL INJURY OR PROPERTY DAMAGE, DO NOT install to control a receptacle.
•  To be installed and/or used in accordance with electrical codes and regulations.
•  If you are unsure about any part of these instructions, consult an electrician.
•   The  Decora
®
 DDS15 is not compatible with standard 3-way or 4-way switches. It must be used with the Decora
®
 Digital DD0SR-DL or DD0SR-10 remote for 
multi-location dimming.
