Tuck wires into wall box(s) leaving room for the device(s).
Using screws provided, mount the switch timer into the wall
box, then install the wall plate.
Turn power back on at the service panel.
You are ready to set the DATE and TIME—Proceed to Section 3.
For 3-way Switch and Other Multiple Switch Setups:
NOTES:
When installing the EJ500 switch timer in circuits with
two or more switches:
The wiring is different when using the EJ500 switch timer
than when using conventional toggle switches. Read the
following installation instructions carefully.
The distance between switch timer and remote switches
must not exceed 100 feet, and wiring to the remote switch-
es must not be buried underground.
Used remote switches from a previous conventional instal-
lation may not function reliably with an electronic timer. Try
a brand new remote switch if function is intermittent.
For Existing 2-Switch (3-way) Installations:
Locate the COMMON wire
connected to first old switch.
It might be attached to a dif-
ferent colored screw, or find
markings on old switch.
Connect BLACK wire from
switch timer to COMMON
wire, using a twist connector.
Connect the other two wires from the old switch to either the
BLUE and RED wires from the switch timer.
Connect the ground wire from the box to the BARE COPPER
wire on the switch timer. If there is no ground wire, ground the
switch timer to the box. If the box is plastic, connect the bare
copper wire to ground as supplied or contact an electrician.
Locate the COMMON on the second old switch of the 3-way pair.
Connect jumper wire (supplied) from the COMMON terminal
to either of the other terminals on the remote 3-way switch.
Make sure all twist connectors are tight.
Tuck wires into wall boxes leaving room for the devices.
Mount the devices into the wall boxes, then install the wall plates.
Turn power back on at the service panel.
Make sure the switch timer displays “MAN” mode. Do the fol-
lowing test with the remote switch in each of its 2 positions:
Press the
NEXT ON/OFF
button on the switch timer several
times. Each time that you push the
NEXT ON/OFF
button, the
switch controlled light or device (the “load”) should turn on
or off. If so, proceed to Section 3.
If the timer display changes between ON and OFF but the
load does not operate, re-check your wiring and make sure
the load is functional.
If the timer display changes
between ON and OFF 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, change the jumper
wire to the other terminal. Then turn power back on at the
service panel and repeat

Self-Adjusting Indoor
Wall Switch Timer
Turn off power at the service panel by REMOVING FUSE or
TURNING THE CIRCUIT BREAKER OFF.
Remove the existing wall switch.
Trim building wires to 7/16” as shown.
For Single-Switch Installations:
Connect one of the two wires
from the wall to the BLACK wire
from the switch timer, using the
twist connectors provided.
Connect the other wire from
the wall to the BLUE wire from
the switch timer, using the twist
connectors provided.
NOTE:
The RED wire is not used in single-switch installations.
Cap with a twist connector.
Connect the ground wire from the box to the BARE COPPER
wire on the switch timer. If there is no ground wire, ground the
switch timer to the box. If the box is plastic, connect the bare
copper wire to ground as supplied or contact an electrician.
Make sure all twist connectors are tight.

Ratings
Before installing the switch timer into the wall, make sure the
supplied batteries are installed and working.
Open the access door to reveal the battery tray, located below
the keypad.
Remove the tab to connect the installed batteries. Make sure
battery tray is pushed fully into place.
The display will initialize itself then flash “12:00 AM” in
MANual mode.
NOTE:
If display doesn’t flash “12:00 am”, the battery may be
dead. Replace the battery before installing the switch timer.

Observed Problem
Possible Cause
What to Do
Timer is blank until any button is pushed,
and display changes between ON and OFF
when pressing door, but light stays OFF.
Bulb is missing, loose, disconnected or burned
out.
Make sure bulb is good and that there are no
other switches, photo controls, etc., in the circuit
controlling the bulb.
“Air Gap”switch at upper edge of timer is
switched off.
Make sure “Air Gap”switch is in it’s ON position
(slid to the left with slider in center of slot).
No power (fuse or circuit breaker blown)
Make sure fuse is good or circuit breaker is on.
Timer does not switch but display is normal.
Timer not in AUTO, AUTO RAND(om), or
MAN(ual) mode.
Press
MODE
to select the desired operating mode.
Timer works manually but does not follow
scheduled program.
Timer not in AUTO or AUTO RAND(om) mode.
Press
MODE
to select AUTO or AUTO RAND.
Timer won’t enter the AUTO or AUTO RAND
modes when MODE button is pushed.
Time of day and/or switching times are not pro-
grammed.
Make sure time of day and at least one scheduled
activity are programmed.
Timer switches at incorrect times or skips
some switching times.
Programmed schedule(s) are incorrect.
Review ALL 7 ON/OFF switching time pairs by re-
peatedly pushing
NEXT/ON/OFF
while in PGM mode
and revise as necessary.
Timer is in AUTO RAND(om) mode (varies
switching times up to ±15 minutes).
Press
MODE
to select AUTO mode.
When using a combination of Astronomic
and Specific switching times, the timer
switches at unexpected times or doesn’t
switch when expected.
There are conflicting Astronomic and Specific
switching time settings. Your timer automatically
skips any conflicting ON EVENTS as summer
approaches to prevent unwanted operation of
lights. See the next column if you wish to identify
and remove conflicting settings.
Complete the steps under “Setting the Calen-
dar.”
Temporarily change your timer’s calendar set-
ting to June 21st.
Review the SUNUP and SNSET times by push-
ing the
NEXT/ON/OFF
button.
Make sure your specific ON or OFF time set-
tings won’t interfere with these Astronomic
switching times.
Be sure to change the date back to today’s date
when you’re done.

Load state doesn’t match programmed state
immediately after programming the time or
schedule.
The timer does not “catch up” to the pro-
grammed load state. Instead, the load will remain
in its current state prior to entering the PGM
mode. The timer will then begin following the
scheduled program at the next contrary ON/OFF
time.
After entering your schedules or the time, then
returning to the AUTO modes, push
NEXT/ON/OFF
to change the load state if necessary.
Load only operates when the remote (3-way)
switch is in one position or timer ignores the
remote switch.
Remote switch is wired incorrectly.
Recheck wiring, especially for the jumper, per
“2–Install the Switch Timer”.
Timer ignores remote (3-way) switch even
though it is wired correctly.
Excessive length of wire (greater than 100 feet) or
buried wiring to the remote switch.
Eliminate condition by replacing the buried cable
or doing without the remote switch. Consult fac-
tory for other options.
Remote switch is defective or worn out.
Replace the remote switch.
Load turns off immediately after being
turned on.
Remote switch or timer wired incorrectly, exces-
sive length of wire (greater than100’) or buried
wiring to remote switch, or defective timer.
If the problem persists with the timer’s red wire
disconnected or with a remote switch temporarily
connected right at the timer, replace the defective
timer. Otherwise try the above remedies.
Battery holder is difficult to snap in place.
Batteries not seated in holder, holder misaligned,
or contact tabs of holder are bent.
Seat the batteries, then install the holder with the
notch facing down.
