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 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
Smart
TM
 DH15S is not compatible with standard 3-way or 4-way switches.
•  Use only (1) 
Decora
Smart
TM
 DH15S switch in a multi-location circuit with up to 9 coordinating remote switches (DD0SR-01Z), or up to 4 matching remote switches (DD0SR-DLZ).
•  Maximum wire length from switch to all installed remotes cannot exceed 300 ft (90m).

NOTE: The switch must be installed in a wall box that has a Line Hot and 
Neutral 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).

(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.
 TOOLS NEEDED TO INSTALL YOUR SWITCH
Slotted/Phillips Screwdriver  Electrical Tape  Pliers   
Pencil    Cutters   Ruler
Changing the color of your Switch:
Your switch comes with two color options. The switch ships with the 
White frame attached. To change color of frame, proceed as follows:

2
Insert top 
tabs and 
press in 
bottom 
tabs to 
attach
Push in 
sides at 
bottom tabs 
and pull 
outward to 
release
Preparing and connecting wires:
This switch can be wired using side wire terminal screws 
or through backwire openings. Choose appropriate wire 
stripping specifications accordingly.
IMPORTANT : For 3-Way applications, note that one of the screw 
terminals from the old switch being removed will usually be a 
different color (Black) or labeled Common. Tag that wire with 
electrical tape and identify as the common (Line or Load) in both the 
switch wall box and remote wall box.
 Step 3
•  Make sure that the ends of the wires from the wall box are 
straight (cut if necessary).
•  Remove insulation from each wire in the wall box as shown.
•  For Single-Pole Application, go to Step 4a.
•  For 3-Way Coordinating Remote (no LED) Application, go to Step 4b.
•  For 3-Way Matching Remote (with LED) Application, go to Step 4c.

•  Green or bare copper wire in wall box to Green terminal screw.
•  Line Hot (common) wall box wire identified (tagged) when removing 
old switch and First Traveler to Remote terminal marked BK.
•  Second Traveler wall box wire from switch to remote terminal screw 
marked "YL/RD" (note wire color). This traveler from the remote 
must go to Yellow/Red switch terminal screw.
•  Line Neutral wall box to remote terminal screw marked "WH".
WIRING SWITCH (wall box with load connection):
Connect wires per WIRING DIAGRAM as follows:
•  Green or bare copper wire in wall box to Green terminal screw.

WARNINGS AND CAUTIONS
• 
TO AVOID FIRE, PERSONAL INJURY OR PROPERTY DAMAGE, DO NOT install to control a receptacle.
•  Recommended minimum wall box depth is 2-3/4".
•  Use this switch with copper or copper clad wire only.
•  Save this instruction sheet. It contains important technical data along with testing and troubleshooting information which will be useful after installation is complete.
•  Leviton HomeKit-enabled accessories rely on Wi-Fi
®
 communication. Increasing the number of Wi-Fi

technology provides an easy, secure way to control HomeKit-enabled 
accessories using Siri voice control on your iPhone or iPad. After 
installing your Decora Smart
TM
 Switch, configure it from the Leviton 
Decora

Home app with just a few simple steps.
WARNING: TO AVOID FIRE, PERSONAL INJURY OR DEATH 
DO NOT USE the remote for the control of high power heating 
appliances such as portable heaters. There can be some unexpected 
consequences if not used with care. For example, an empty coffee pot 
can be remotely turned on. If that should happen, your coffee pot could 
be damaged from overheating. If an electric heater is turned on by 
remote control while clothing is draped over it, a fire could result. This 
switch will not control lighting that is used with electronic low-voltage 
and high frequency power supply transformers, nor high pressure 
discharge lamps (HID lighting). This includes mercury-vapor, sodium 
vapor and metal halide lamps.
