Black — Connects to the hot (black) wire from the Power
Source
B
Blue — Connects to the other wire (black) from the load
C
Red — This wire is not used in single-switch installations.

D
Green — Connects to the supplied ground
Three-Way Wiring
Note: The distance between the timer and the remote
switch must not exceed 100 feet.
A
B
C
D
A
Black — Connect to the wire removed from the "COMMON"
terminal of the switch being replaced
B
Blue — Connect to one of the other wires removed from the
switch being replaced. Record the wire color connected
to the blue wire for use during load-side installation
C
Red — Connect to the remaining wire removed from the switch
being replaced. Record the wire color connected to the
red wire for use during load-side installation
D
Green — Connect to the supplied ground
Note: Connect the timer on the line-side.
Note: Consult a qualified electrician:
• If you have trouble differentiating the wiring
colors for the building.
• When using a single-pole switch at the
remote location for new construction or to
replace a dimmer switch, a lighted switch,
or a three-way switch without screw
terminals.
Finalizing Installation
1. Make sure the twist-on wire connectors
(provided) are secure, then tuck the wires into the
timer wall box, leaving room for the timer.
2. Using the provided screws, secure the timer to
the wall box.
3. Cover the timer with the wall plate and secure
using the provided screws.
4. For three-way wiring, install the remote switch in
a wall box. Cover the switch with the wall plate
and secure.
5. Reconnect the power at the service panel.
TESTING THE TIMER
1. To test the battery, press ON/OFF. The timer
should "click."
2. Make sure the timer displays MAN mode during
testing.
3. For three-way wiring, test the remote switch in
each of its two positions by pressing ON/OFF
several times. The timer should "click" and the
controlled light or device (load) should turn ON
or OFF.
4. For three-way wiring, if the timer clicks, but the
load does not operate:
a. Disconnect the power at the service panel.
b. Re-check your wiring and make sure the
load is functional.
c. Reconnect the power at the service panel.
d. Retest.
5. For three-way wiring, if the timer clicks, but the
load only operates when the remote switch is
in one of its two positions, repeat Step 4, a-d,
paying close attention to the wiring that connects
with the red and blue wires of the timer.
Note: Consult a qualified electrician if the switch and timer
fail to operate as intended.
When the timer "clicks" and the controlled device
turns ON and OFF as appropriate, congratulations,
the timer is successfully installed! Enjoy your new
timer!
