INTRODUCTION
This easy to program microprocessor-based time switch provides
flexible 24-hour, 7 day or full year load control. Its unique
“self-prompting” feature simplifies programming by leading you
through with flashing prompts. The 2 rows of LEDs on the left
side flash and indicators in the digital display light while you are
programming to identify information that needs to be entered.
SET UP information must be entered first, followed by the
PROGRAM information. PROGRAM is used to set the switching
times of the loads controlled by the time switch. Switching times
can be programmed in any combination of:
LED DISPLAY
The red LED display prompts and indicates data as it is entered in
SET UP and PROGRAM. The display indicates current time in the
RUN mode. Note the dual captions above and below the display.
RESET
Operation begins with RESET, followed by data entry with the
keypad. Pressing RESET initializes the time switch by testing and
clearing the working memory and turning off all circuit loads.
(Pressing RESET during programming will cause all data just
entered to be lost.) To clear all existing program and setup data,
press and hold the CLEAR button, then press and release RESET.
Continue to hold CLEAR until RESET appears in the display.
Fixed–Switch ON times and/or Switch OFF times that are based
on a user-selected time of day and can only be changed by
reprogramming.
Pulse–The same as fixed times except the ON or OFF operation
occurs only for a short duration (1 to 127 sec.) as required for bell
ringing, signal control or the operation of latching relays.
Interval–The same as Pulse times except for a longer duration
(from 1 min. minimum up to 6 days, 23 hrs., 59 min.).
Interval also allows programming for a user selectable override.
Astro–Based on the changing times of sunset and sunrise.
Before proceeding with programming:
• Read the instructions on pgs. 3–14
• Review the programming example on pgs. 14–16
• Complete the charts on pgs. 17–25
• Install time switch, connect ground wire as shown on pgs. 28–30
• Complete wiring by referencing examples on pgs. 31–32
While programming be sure to assign the various switch times to
the appropriate loads with the Enable switch. When you are
finished, the REV (Review) key allows you to check the program
before leaving the installation.
2
RUN/SET
You must have this switch in the SET position to enter, review or
clear data. When you have finished, slide the switch to RUN to
automatically save the data into non-volatile memory. If entering a
large number of set points, you may wish to periodically move the
slide switch to RUN to save your data. Return to SET after SAVE
disappears from the display and continue programming. If a power
outage occurs and you are in SET, all data not saved will be lost.
The data is permanently stored unless the memory is deliberately
erased (by pressing RESET while holding down the CLEAR button).
Data can only be modified by the user. In the event of power
failure the non-volatile memory holds the data even if the battery
backup should fail. When moving this switch to RUN, the
message SAVE briefly appears in the display. When moved to
SET the message RECALL appears briefly.
Data entry falls into the two categories shown on the front panel:
SET UP and PROGRAM.

SET UP
SET UP is performed once during
installation to set the internal CLOCK, ASTRO (sunrise/sunset)
times and HOLIDAY references. After entering and okaying the
ASTRO Zone, the timer will display calculated “center of time
zone” times when prompting for sunrise and sunset entries. You
may OK these, enter actual sunrise/sunset times or enter offset
times for early or late ASTRO operation. Sunrise time must be
before noon; sunset time must be after noon. Sunset must not be
within 5 hours of sunrise. Both sunrise and sunset must be
entered, even if only one is used for switching. If neither is
required, you may skip ahead by pressing HLDY or PROG keys.
(See map pp. 26–27 for details.) Holidays are entered with 2-digit
reference numbers; a chart for recording the date(s) is located on
page 21. Leap years are preset through the year 2094.

These keys are used for most data entry. Note dual functions,
numeric or day specific. Using the day group keys WKDY,
WKND and ALL (for all 7 days) greatly speeds the process.
The keypad keys are only functional when the RUN/SET switch is
in the SET position. Pressing keys when in the RUN position will
cause a message to scroll, explaining the function of that key. Press
any key once to stop any of the scrolling error or help messages.

PROGRAM
PROGRAM is used for entering or
changing the switching schedule for loads wired into the time
switch. You can program circuits separately or concurrently. Each
entry affects loads whose Enable switches are in the enable
position at the time of data entry. The time switch is shipped in a
12-hr. AM/PM mode; you can change to 24-hr. by removing a
jumper on the circuit board (see Special Instructions). It can store
a minimum of 400 events, depending on the data type entered.
The time switch prompts you through SET UP and PROGRAM
with LEDs that advance after each entry. There are five important
points to remember:
1)
The RUN/SET
switch must be in the
SET
position to enter,
review or change data.
2) You must press “OK” after each entry, before starting the next.
3) You must press AM or PM after entering time (unless
programming Sunrise and Sunset or in 24-hour mode).
4) When in PROGRAM you must select the loads you want to
control with the Enable switches.
5) RUN/SET switch must be returned to RUN position to enable
automatic control and to save changes to data.
4
You must press AM or PM after entering time data (except Sunrise
or Sunset) unless in 24-hr. mode. Programming fixed times for
ON and OFF times does not require PULSE, INTVL or ASTRO
keys. Multiple ONs or OFFs can be entered by pressing OK
without programming the alternate OFF or ON. Multiple OFF
times are frequently used to “sweep” off loads which have been
manually switched on after normal occupancy hours.
PULSE and INTVL (Interval) are length-of-time based options.
Maximum Pulse is 127 sec.; minimum is 1 sec. Maximum Interval
is 6 days, 23 hrs., 59 min.; minimum is 1 min. To program Pulses
or Intervals, press the PULSE or INTVL key after entering a Switch
On or Switch Off time; then enter the required duration and press
OK. Note after On Pulses or Intervals have timed out the load
will be Off, and after OFF Pulses or Intervals have timed out the
load will be ON, regardless of the load state prior to the start of
the Pulse or Interval. The INTVL key includes a temporary
override function with a maximum length of 6 days, 23 hrs., 59
min. To program an interval for override, enable a circuit, press
INTVL (without selecting a day), key in the duration and press
OK. Remember INTVL override
is initiated on demand via the
keypad and is not based on a day

and time, as is normal INTVL. To initiate an override interval, set
the RUN/SET switch to RUN, set the switch for the desired load
to Enable, press the INTVL key and hold, and press the ON/OFF
button for the load you wish to override. The green load indicator
flashes during the interval to show override selection. At the end
of an override interval the load and green LED will turn off,
regardless of the load state before the override or prior programmed schedules. The load will respond to any subsequent program
schedules. An override interval may be ended early only by pushing
the ON/OFF button, or by a power interruption. Thus, a programmed Off event will not end an override interval. The actual
override interval duration is the programmed duration ± 30 sec.,
dependent on the instant in time when the override was initiated.
The Remote Override feature allows a switch contact to initiate an
override interval. The timer detects the closing or opening of
switch contacts wired to the Remote Override Connector (on back
of Logic Module). This allows the remote switch(es) to be maintained (toggle) or normally open or closed momentary (push
button). As with the front panel initiated override interval, the
relevant circuit must have an interval duration programmed, and
its slide switch must be in the Enable position, before an override
interval can be initiated. Any additional remote switch activity
during an override interval will restart the interval. The remote
override may not be used for applications requiring a pulse output,
or to turn loads Off remotely. See Special Instructions for wiring.
ASTRO is pressed (instead of a time entry) after selecting a day
or day group if you want switching to occur at Sunrise and/or
Sunset.
To program ASTRO switching with a Pulse or Interval, press
ASTRO, then PULSE or INTVL, followed by entering a pulse or
interval duration. . .all before OK is pressed.
(Clock adjustment for Daylight Savings Time is automatic; see
Special Instructions for override if DST adjustment is not
required, such as in Arizona, Hawaii and parts of Indiana. The
clock time will be adjusted by 1 hour on the first Sunday of April
and the last Sunday of October at 2:00 AM. Due to unexpected
results, it is recommended you do not attempt programming from
12:00 midnight to 2:00 AM on these two days.)

HLDY
return you to the beginning of these
categories. Press PROG to select a new day/day group when
programming of a selected day/day group is complete, or to skip
Astro and/or Holiday prompts during SET UP.
REV (Review) allows you to check SET UP or PROGRAM data.
The holidays will review in chronological order regardless of the
order in which they were entered. CLEAR is used during Review
to delete displayed data if changes are required.
The Holiday (HLDY) feature allows the timer to follow special
schedules on selected days or periods of days, based on the date
instead of the usual 7 days of the week. Although Holiday
schedules are normally used to modify or suspend regular weekly
switching activity on actual holidays, the Holiday feature also
allows a variety of special scheduling options that are not satisfied
by the 7-day repeating schedule. See Programming Examples
supplement for details. Each holiday may be one day long or as
many days as necessary. Although each has a reference number
(1–99) that you assign, Holidays occur and review in chronological order, so the order of the reference numbers does not matter.
HLDY (Holiday) allows you to set up or review Holiday data. If a
holiday is a single day, press OK when prompted for the STOP
date, or enter the same date. If you need to switch loads on a holiday, press PROGRAM, press HLDY, enter the reference number
1–99 for that holiday, then press OK. Program the holiday load
schedule just as you would any day or day group. If you do not
program switching times for holidays, the loads will be inactive
during the holiday period; all loads will remain in the state they
were at 11:59 PM on the day preceding the start of the holiday.
You may program Off events at 12:00 AM on holidays to
guarantee loads are off during holidays. Note the STOP date is the
last day the loads will be inactive or under special program
control. The following day the loads will resume normal
scheduling beginning at 12:00 AM. Press PROG to exit the
holiday mode after entering
the last holiday.

Holiday schedules and dates will remain in timer memory until
deliberately cleared. For those Holidays whose dates vary from
year to year, you must manually revise the start and stop dates (in
SET UP review) annually. Holidays may not be programmed to
end before their start date and must end by Dec. 31.
4) The COPY feature copies the programmed schedules of all the
circuits of the copy from
the copy to
day regardless of the positions of the circuit Enable
day to the corresponding circuits of
switches. Individual circuit schedules may not be copied
independently.
COPY

OK
The OK key must be pressed after

each complete entry; pressing it
advances you to the next data prompt. The OK key is similar to
an Enter key. After okaying a switching time, the timer automatically prompts for the alternate switching activity; i.e. Off after
On, On after Off (except after a pulse or interval entry). Pressing
the OK key without making another switching time entry alternates the On/Off prompt, allowing a succession of Off or On
events. OK is the final step after programming all steps and
enabling circuits for each switching time/type.
CLEAR clears the last digit entered; additional digits are cleared
from the display each time CLEAR is pressed. CLEAR is also used
to clear an error code or message and return the display to the
same data that appeared before attempting to OK the data.
While in Review pressing CLEAR deletes the displayed data from
the program for the load(s) selected with Enable. Press REV to
continue Review.
COPY allows you to use the same schedule for groups of days
other than those available on the keypad (WKDYs, WKNDs or
ALL). Simply press COPY after entering a schedule for a specific
day, and at the DAY prompt key in the day you wish to copy to.
You may also copy a day that was previously programmed by
pressing that day’s key, pressing the OK key, then the COPY key.
The display will show the selected day followed by COPY. Now
key in the day you wish to copy to and press OK to confirm.
Select and OK additional copy to
days as required. Four rules
need to be followed when using COPY:
1) You cannot copy to
2) You cannot copy from
3) You cannot copy to or from
a day that has already been programmed.

HELP provides help messages specific to each step in SET UP and
PROGRAM. If you make an error, it will be indicated in the LED
display with an error code. (See Error Messages at the back of this
booklet, or press HELP to scroll the message across the display.)
Pressing any key or allowing the message to finish returns the display
to the same point you were at before the error was made.
LOAD CONTROLS
There are two controls and an LED indicator for
each load. Enable/Disable activates automatic
switching of the load by the time switch, enables
the override function in RUN mode and selects
circuits being programmed in SET mode.
The ON/OFF key manually switches the load independently of the
time switch and cancels any previously initiated activity, including
PULSEs, INTVLs (Intervals) or override intervals. The ON/OFF key
does not interfere with events that occur after its use. The ON/OFF
keys and LEDs will operate the loads and indicate status regardless of
the position of the RUN/SET switch. When timer power is restored
after a power interruption, all loads will initially be Off. The timer
then restores any enabled loads to their programmed status as of midnight (12:00 AM) of the present day. For this reason,for On periods
that include midnight, if load operation is desired immediately after
power restoration, use a redundant On set point at each affected
midnight (12:00 AM) to guarantee predictable catch-up.
If more than one load is scheduled to turn On, the soft start feature
will turn them On successively at 15 sec. intervals. Therefore, it is
generally advisable to put lighting loads on low-numbered circuits to
hasten their turn-on after power is restored. All same-scheduled loads
turn Off
simultaneously at the scheduled time. If a soft start is not
desired, program those loads using
interval or pulse.
Next Generation

If a soft start other than the factory setting of 15 seconds is desired
press SET UP; and the date will be displayed. Then press
PULSE: SS (for Soft Start) appears in the left two displays with
3 dashes in the rightmost displays. Enter the soft start desired
by keying in a number from 1 to 127 seconds, and then press OK.
This new soft start allows you to lengthen or shorten the
15-second soft start and will affect all available circuits.
INSTRUCTIONS FOR REVIEWING/REVISING DATA
REVIEW PROCEDURE
• Place the Run/Set switch in the Set position to review.
• You must review Clock info (date, time), Astro and
Holiday dates in SET-UP mode.
• You must review all load activity (Fixed times, Astro times, Pulse
operations, Interval operations and special “Holiday” load
activities) in PROGRAM mode.
• In PROGRAM, select only one load at a time using the
ENABLE switch. If more than one circuit is enabled, you will
only see switch activities common to all Enabled circuits.
REVIEW CLOCK, CALENDAR, ASTRO DATA AND
HOLIDAY DATES
To initiate review, press SET-UP (the date is displayed), then press
REV (Review). Continue to press REV for each program you wish to
review. SET-UP stops after the time is displayed if no ASTRO
information has been entered, allowing you to enter Astro data
(Zone, Sunrise and Sunset). If ASTRO information has been entered,
pressing REVafter reviewing the Sunset time will cause the message
“End of Review” to be displayed. Review will then automatically
advance to HOLIDAY, allowing you to select a specific holiday
reference # (01–99) for review. If you want to review all holiday
dates, press REV without selecting a reference number, and the first
reference # will appear. (Not necessarily reference #1 since
holidays review in chronological order beginning Jan. 1). Continue
to press REV to walk through the Ref # and the Start and Stop
dates for each holiday until “End of Review” is displayed. For single
day holidays, Start and Stop dates will be the same. Note Astro
sunrise and sunset times are re-calculated daily by the timer and will
differ from times entered or reviewed on a previous date.
REVISE SETUP DATA
To revise or delete displayed information during Setup Review,
simply press CLEAR. When reviewing Astro Sunrise and Sunset
times, you may need to press CLEAR more than one time since
each operation deletes only one digit. You can then immediately
make the revision. Be sure to press OK to enter the new data.
Note that after any revisions to the sunrise Astro time, the sunset
Astro time must be re-entered and okayed. Press REV to continue
the review.
REVIEW PROGRAM
• Be sure to select one load at a time. Failing to do so will allow
you to only review switching activities which are common to all
the circuits selected. In other words, if circuits #1 and circuits #2
are both enabled and are both programmed to come ON at 8:00
A.M., but OFF at different times, the 8:00 A.M. ON time will
be the only set point shown in Review. You must be in the
PROGRAM mode in order to review the programmed load
activities.
• In the PROGRAM mode, you can review switching activities
regardless of whether you programmed them as Fixed Times,
Astro Times, Pulse Switching or Interval Switching. Special
Holiday load activities or interval overrides are also reviewed in
Program.
REVIEW WEEK LONG SWITCHING ACTIVITIES
The normal load switching schedule is a composite of all
applicable individual day schedules, day group schedules and
copied days.The week long review feature allows this composite
schedule to be easily reviewed; by simply pressing the REV key
repeatedly, without first selecting a day, the timer will step thru all
scheduled switching times chronologically, beginning at 12:00
AM Sunday, or by pressing the REV key once, then pressing the
OK key, the timer will automatically step thru each scheduled
switching time, displaying each time for about 2 seconds. Press the
OK key to pause auto review. Press the OK key again to resume
auto review; or press the rev key to continue review manually.
The scheduled switching times may only be reviewed, not cleared
during week long review. Follow the steps below for individual
day/day group review if any scheduled events need to be cleared.
