3-Way Switch Setup
NOTE:
The distance between switch timer and remote switch must
not exceed 100 feet.
1. Locate the COMMON wire connected to fi rst old switch. It might
be attached to a different colored screw, or fi nd markings on old
switch.
2. Connect BLACK wire from switch timer to
COMMON wire, using a twist connector.
3. Connect the other two wires from the old
switch to the blue and re wires from the timer.
4. Connect green wire to grounding screw in the box.
If plastic box, connect to ground.
5. Remove wire “C” from the “Common” terminal of
the existing remote switch.
6. Reconnect wires “B” and “C” to the common termi-
nal of your remote switch, using the supplied piece
of jumper
wire. If using a new single-pole remote
switch. See diagram 3.
NOTE:
For new construction or replacing a dimmer switch, a lighted switch, or a 3-way
switch without screw terminals, a single-pole switch can be used at the remote location. If
unable to determine the proper wire colors, choose one of the wires and connect as wire B.
After the installation is complete, if the controlled light or device will not turn on properly,
reverse wires “A” and “B”. See Steps 11 and 12 for how to check.
7. Tuck wires into the timer wall box leaving room for the timer.
8. Using screws provided, mount the switch timer into the wall box, and install wall plate.
9. Install the remote 3-way switch in its box and install wall plate. Turn power ON.
10. Make sure
MAN
mode appears.
11. Press
ON/OFF
button on the switch timer several times. Each time you push the
ON/
OFF
button, the switch timer should ‘“click” and the controlled light or device (the “load”)
should turn on or off. If so, proceed to Step12
.
- If timer clicks but load does activate, check wiring and make sure load is functional.
-
If the timer clicks but the load only operates when the remote switch is in one of its
2 positions, you need to turn off the power at the service panel, then reverse wires
“A” and “B”. You can reverse wires “A” and “B” at the remote switch wall box, or you
can reverse wires “A” and “B” where they connect to the red and blue wires of the
switch timer. Then turn power back on at the service panel and repeat Step 11.
12
.
Verify the controlled load turns on or off each time the remote switch is operated.
Multiple Time Switch Setup
Multiswitch applications using the ST01 timer are wired differently than conventional
toggle switches. Read the following installatin instructions carefully.
•
Multiple timers may be mounted in an unlimited number of adjacent junction box slots
•
No derating is required for multiple switch timers.
