Installation Tips!
Incorrect installation may be dangerous or illegal.
Multiple circuit breakers may need to be de-energized for safe
installation. If you are not familiar with electrical work,please call
a professional electrician.
Line Wire : A line wire is a wire carrying an electric current. If
you keep your tester here, it will show indication when power is
there.
Load Wire: The load wire connects your light switch to
your light fixture.It is usually attached to a brass terminal on the
previous switch. It is sometimes black or red.
(IF YOU INSTALLED THE DIMMER NEXT TO OTHER DIMMERS OR
SWITCHES, YOU'LL NEED TO INSTALL A WALLPLATE WITH THE CORRECT
SIZE/NUMBER OF OPENINGS TO ACCOMMODATE ALL THE DEVICES.)
Neutral Wire: A neutral wire which normally in white
color allows the switch to be powered while simultane-
ously allowing the lighting circuit connected to your
lights to be power off.
Ground Wire: Ground wire is a bare copper wire that
provides a conducting path to the earth.
If the wires in your switch wall box are different from the
ones listed below, we recommend consulting a qualified
electrician.
CAUTION: Risk of electric shock. Do NOT touch any
wires during this process.
Option 1: Search for our app in the APP Store or
Google Play.
Option 2: Scan the QR code below to enter the
download page.
Tip #1: An easy way to identify the wires in your
wall box is by looking at the color.
●After removing the face plate, turn the
breaker back on.
●Very carefully, press the voltage pen
against each wire.
●The pen will glow red when the wire is hot.
●The wire that causes the pen to glow red
is the hot wire; also known as the Line wire.
●The wire that does not cause the pen to
glow red is the Load wire.
CAUTION: Risk of electric shock. Before continuing
with the rest of the installation process, make sure to
turn the power breaker off.
Identify whether the switch is at the
input end ?
Turn on the power at the circuit breaker and turn off the
switch. (Attention: Do not touch the switch circuit or
screws with your hands)
Use a Voltage tester to check the black screw on the old
switch.
If the detection result is not the line wire, then this
position is the output end, the dimmer switch is not
suitable for this position. Please turn off the power,
reinstall the old switch back onto the wall, and then select
the switch on the other end for replacement.
Note: If one of the two traditional three-way switches
connected to the device malfunctions, you need to move
the traditional three-way switch originally connected to
the line wire to the position where the device is
connected, and replace the traditional three-way switch
connected to the line wire with a smart three-way switch.
Shut OFF the power at the circuit breaker for
the switch you are replacing.
Install the 3-way smart dimmer switch SW17. Insert
your wires to the terminal, then tighten the screw.
In case you need jumper wire, the switch comes
with extra jumper wires and caps.
You may need to shut OFF
more than one circuit
breaker/switch to make sure
the switch you're working onis
powered OFF.
IMPORTANT: USE A NON-CONTACT VOLTAGE
DETTECTOR OR FLIP YOUR LIGHT SWITCH A FEW TIMES
TO MAKE SURE THAT THE POWER IS OFF.
Remove the wallplate
from switch.
Remove the switch and pull it
away from the wall.
Be sure to find the old switch that the line wire
was connected to. Unscrew the old switch with
a screwdriver and pull it out of the wall.
Disconnect all wires from the switch. Please note: replace the
traditional 3-way switch which connected to the Line wire.
Use a flat-head screwdriver to pry open the panel.
Then close the top cover.
Mount the device using the provided screws.
Turn power on at circuit breaker.
