SwitchLinc’s LED bar and connected light will turn on
Only SwitchLinc in box 2 will operate the Load until you synchronize Scenes to both
SwitchLincs in next step
20) Add both SwitchLincs to a Scene as a Controller and Responder of each other (see
Synchronized
Scenes)
21) Verify SwitchLinc(s) are working properly by tapping SwitchLinc’s paddle turning light (load) on and
off
22) Reinstall wallplates
Installation – Circuit with 3 or more Switches (3-way/4-way)
Circuits with 3 or more switches are called 3-way/4-way circuits. All switches in 3-way/4-way circuits need
to be replaced by SwitchLincs (and/or KeypadLincs).
Note: 3-way/4-way circuits require a pair of wires called Travelers between joining wall boxes to operate.
INSTEON switches, dimmers and keypads do not require both Traveler wires for 3-way/4-way circuits to
function. Simply wire one to Line, Neutral and Load; the other(s) to Line and Neutral. Use one Traveler to
share Line between boxes. Adding to a Scene creates a virtual 3-way/4-way circuit.
The following example shows three switches
1) Turn off circuit breaker(s) and/or remove fuse(s) feeding wall boxes
2) Use a voltage meter to verify that power is off
3) Pull all three switches from their wall boxes, each existing 3-way switch will have a minimum 3 wires;
4-way switches will have a minimum 4 wires
4) Remove wires from existing switches
5) Make sure wires are safely separated from each other and turn breaker(s) back on
6) Using a voltage meter measure each wire to Ground in all three boxes until you find the single wire
supplying 100 - 277VAC (Line)
a. We will now refer to that location as box 1
b. The location having 2 sets of matching pairs of wires will be box 2 (e.g. 2 Reds and 2 Blacks,
or other matching colors). These are 2 Travelers from box 1 and 2 Travelers leading to box 3.
c. The last box will have the Load wire, that will be box 3
7) Turn breaker(s) back off
In Box 1 (Line box)
8) Connect bare Ground wire from
SwitchLinc to bare Ground wire or
Ground screw in the wall box
9) Connect White Neutral wire from
SwitchLinc to Neutral wire(s) in wall
box (usually white)
10) Cap Red wire from SwitchLinc
11) Connect Black wire from SwitchLinc to
100 - 277VAC Line wire in wall box
(usually Black) along with one Traveler
wire running between boxes
(preferably Black). Note color of
Traveler you are using as this will carry
Line voltage to box 2.
12) Cap unused Traveler wire
In Box 2 (Traveler box)
