1. Disconnect the power at the circuit breaker(s) or
disconnect switch(es).
2. Remove wall switches, if applicable.
3. Strip the existing wire ends
to 7/16”.
4. Wire the timer into the wall box.
• For an example of single-pole wiring,refer to
“Single-Pole Wiring”.
• For an example of three-way wiring, refer to

being replaced. Record the wire color connected to the
red wire for use during load-side installation

Notes:
• Connect the timer on the line-side.
• 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 circuit breaker(s) or
disconnect switch(es).
TESTING THE TIMER
1. Make sure the timer displays MAN mode
during testing.
2. 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.
3. For three-way wiring, if the timer clicks, but
the load does not operate:
a. Disconnect the power at the circuit
breaker(s) or disconnect switch(es).
b. Re-check your wiring and make sure
the load is functional.
c. Reconnect power at the circuit
breaker(s) or disconnect switch(es).
d. Retest.
4. 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 3, 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 controlled device turns ON and OFF
as appropriate, congratulations, the timer is
successfully installed and ready for programming!
NOTES
Read these notes before continuing with the timer
programming process.
• Your timer contains a built-in, non-replaceable,
rechargeable battery to maintain the date and
time of day information for at least 4 consec-
utive days of AC power interruption. All other
user settings are maintained indefinitely without
AC power. The built-in battery will fully charge
within a day of connection to AC power. After
an extended power outage, if the display is
flashing “12:00 AM”, you will need to re-enter
the calendar, time, and day information.
• The CAL and CLK settings must be pro-
grammed before ON or OFF events can be set.
• Each ON or OFF setting is an event. Each event
must be programmed separately.
• All menus loop (repeat options when you get to
the end of the menu).
• When advancing to the next setting, the timer
automatically saves the data from the previous
screen regardless of setting changes. All set-
tings save automatically after five minutes.
