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 Step 11.

You are ready to set the DATE and TIME—Proceed to Section 3.

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.
