the supplied jumper wire between
wire B and the common terminal
Finalizing Installation
1. Make sure the provided twist-on wire connectors
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
wall box. Cover the switch with the wall plate and
secure.
5. Reconnect the power at the service panel.
TESTING THE TIMER
Make sure the timer displays MAN MODE during
testing.
Single-Pole Wiring Test
To test the timer, press ON/OFF several times. The
timer should “click” and the controlled light or device
(load) should turn ON or OFF.
Three-Way Wiring Test
1. To test the timer, test with the remote switch in
each of its two positions.
2. Press ON/OFF several times. The timer should
“click” and the controlled light or device (load)
should turn ON or OFF.
3. 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.
4. If the timer clicks, but the load only operates
when the remote switch is in one of its two
positions, repeat Step 3, a-d, but interchange the
two traveler wires (wires between the timer and
the remote three-way switch) connected to the
red and blue timer wires.
Note:
Consult a qualified electrician if the switch and timer
fail to operate as intended.
5. When the timer “clicks” and the controlled
device turns ON and OFF as appropriate,
congratulations, the timer is successfully installed!
Enjoy your new timer!
