Multiple timers may be mounted in adjacent junction box slots.
No derating is required for multiple timers.

Wiring diagram, 2 switch installation (3-way) using a single pole remote switch:
Wiring diagram, 3 switch installation:
For 3 or more switch operation, AN ADDITIONAL WIRE MUST BE ADDED between the load and the timer.
The jumper wire is not required for these applications.
4 or more switch installation:
For 4 or more switch installations use the preceding 3 switch installation diagram and wire 4-way switches
between the two 3-way switches.
Installations including a Dimmer:
• The load size and type must not exceed the rating of the dimmer.
(Typically 600 watts, 120 VAC, 60 Hz, incandescent lamps only.)
• If the dimmer is placed in it’s ‘OFF’ position, the timer cannot operate the lights.
• If the dimmer is set too low, the lights may not turn back on under timer control. If necessary, use a
premium quality dimmer that can be turned on at very low settings.
Multi-switch installation using a dimmer :
A 3-way dimmer should not be used. If a multi-switch installation is required, use the following diagram.
NOTE: For new construction or to replace a dimmer switch, a lighted switch, or a 3-way switch without screw
terminals, a single pole switch can be used at the remote location, as shown below.

Special applications
Because of it’s unique “hard contact” switch feature, your timer may be used for applications not previously possible
for electronic wall timers, such as use with dimmers, use without utility power, use on circuits other than 120 volts,
controlling relays or contactors, or to control DC voltage (for example in recreational vehicles). See instructions
above for dimmer applications. For DC and high voltage applications please note the reduced load ratings on prod-
uct label. Consult factory for application details.
TROUBLESHOOTING GUIDE
Timer does not operate, display is dim, blank or unreadable, dis-
play shows nonsense or ‘lobAt’, or timer operates erratically.
Battery is worn out, missing or is installed backwards, or timer
was operated while battery was removed.
Install a fresh AA size alkaline battery in the direction indicat-
ed. Press RESET button, then reprogram timer.
Timer does not switch but display is normal.
Timer not in AUTO, AUTO RAND(om), or MAN(ual) mode.
Use MODE pushbutton to select the desired operating mode.
Use MODE pushbutton to select AUTO or AUTO RAND
Timer not in AUTO or AUTO RAND(om) mode.
Timer works manually but does not follow scheduled program.
Timer won’t enter the AUTO or AUTO RAND modes when
MODE button is pushed.
Time of day and/or switching times are not programmed.
Make sure time of day and at least one scheduled activity are
programmed.
Review / Revise ALL 6 ON/OFF switching time pairs by repeat-
edly pushing the ON/OFF/EVENT button while in PGM mode.
Programmed schedule(s) are incorrect.
Use MODE pushbutton to select AUTO mode.
Timer is in AUTO RAND(om) mode (Varies switching times up
to +/- 15 minutes).
Timer switches at incorrect times or skips some switching
times.
After entering your schedules or the time, then returning to
the AUTO modes, push the ON/OFF/EVENT button to change
the load state if necessary.
Timer does not “catch up” to the programmed load state. The
load will remain in it’s state prior to entering the PGM mode.
The timer will begin following the scheduled program at the
next contrary ON/OFF time.
Load state doesn’t match programmed state immediately after
programming the time or schedule.
Display shows ‘no Op’.
Mechanism is inoperative.
If timer is in a very cold environment, try again when warmer.
If not, and if the battery is good, the timer should be replaced.
Push in battery cover until you hear a click. Push reset button
to clear display and reprogram the unit. Replace device if NoOp
will not clear from display.
Make sure timer display shows ‘ON’ then check dimmer oper-
ation at full brightness setting. If timer control is required at
very low brightness settings, use a premium quality dimmer
that can be turned on when set low.
Dimmer is turned off or is set too low to turn back on or the
bulb is burned out.
Timer operates, but light doesn’t come on in dimmer applica-
tions.
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
“Installation
Instructions - 3-Way Switch”
and
“Other Installations”
.
Eliminate condition, replace the buried cable, do without the
remote switch, or consult factory for other options.
Replace remote switch.
Excessive length of wire (greater than 30 feet) or buried wiring
to the remote switch.
Remote switch is defective or worn out.
Timer ignores remote (3-way) switch even though it is wired
correctly.
REMEDY
POSSIBLE CAUSE
SYMPTOM
Note:THE REMOTE SWITCH(ES) MAY NOT FUNCTION RELIABLY WHEN THE ACCUMULATED WIRE
LENGTH TO THE REMOTE SWITCH(ES) EXCEEDS 30 FEET OR IF THE WIRING TO THE REMOTE
SWITCH(ES) IS BURIED UNDERGROUND. Consult factory for details.
Note: Used remote switches from a previous conventional installation may not function reliably with an electronic
timer. Try a brand new remote switch if function is intermittent.

Battery holder is difficult to snap in place
Battery not seated in holder, holder misaligned, or contact tabs
of holder are bent.
Make sure the “+” end of battery is tucked under the plastic tab
of the holder. Line up tabs on bottom of holder with notches
in timer housing when pushing in. Straighten bent contact tabs.
Load turns off immediately after being turned on.
Remote switch or timer wired incorrectly, excessive length of
wire (greater than 30’) or buried wiring to remote switch, or
defective timer.
If the problem persists with the red wire disconnected or with
a ‘remote’ switch temporarily connected right at the timer,
replace the defective timer, otherwise try the above remedies.
