KEY FUNCTIONS

BATTERY SWITCH

Slide to “ON” before any scheduling is made.

RUN-SET Slide Switch

Allows the user to choose in the RUN MODE the function
that will be reviewed. In the SET MODE the MODE
SELECT key will allow the user to step through or choose
the functions to be set or changed. i.e. Schedule, Astro, etc.
Appropriate light indicator will allow the user to know what
function is being accessed.

REVIEW

In the RUN MODE, the REVIEW KEY serves to review the
functions available in the unit by stepping through it. In the
SET MODE, the REVIEW KEY serves to display the entries
that may be either left alone or deleted.

DELETE

The SET MODE allows the user to DELETE any entries
while reviewing.

ADVANCE (ADV)

In the SET MODE, the ADV KEY serves as a cursor in
order to move through the information displayed in the front
panel. It is a “STEP” key that allows you to move through
the different data that was entered, such as channels, time
of operation, days of the week, etc.

ENTER

Sets the information being entered into the unit’s memory.

PROGRAMMING SUMMARY

RUN MODE

Displays the current time (AM/PM format only), day of
week, and channel status as per schedule. In this mode,
the user can review all the following menus without
accidental modification:

YEAR DATE TIME

HOLIDAY

SCHEDULE

OVERRIDE

ASTRO

SET MODE

In the SET MODE, flashing LED’s guide user at the
appropriate times, to enter, change, review or delete
data in the five modes listed above. A flashing
channel LED, for example, is asking the user to enter
a new channel # or use the one that is flashing. Also,
a pair of flashing colons are asking for data entry into
display which could be year, date, time, etc. This
feature is the keynote to programming the unit.

Another feature is that any new entry or changes
(note that data entry/change is possible in the SET
MODE) will become active only when the SET/RUN
switch is moved from SET to RUN position. However
any existing entries would continue to be executed
while the SET/RUN switch was in the SET position.

After setting schedules and other data the SET/RUN
switch is moved to the RUN position. The unit will
then execute the true status of the circuits and no
manual ON/OFF is necessary.

The same will happen when the user sets a new
time; the circuit status would be current immediately.
(Look back feature).

Any time a key is pressed an audible signal is
generated (one beep). Every time the entry or
information is entered into the unit’s memory a
double beep signal will be generated. Errors will
generate a multiple-beep signal.

In order for any channel to execute its schedule, the (ON­AUTO-OFF) switch must be in the AUTO POSITION.

SETTING THE SCHEDULES

Be sure battery switch is ON.
It is advisable to first layout schedules on the schedule

sheets supplied.

IMPORTANT: TO SET DAYLIGHT SAVINGS TIME,
PLEASE SEE ADDENDUM ON PAGE 7 AND EXECUTE
PRIOR TO SETTING SCHEDULES..

If the unit was started for the first time or if memory is
empty, the display shows a flashing SUN 12:00.

If the unit display shows a specific time indicating it retained
old time and data, then proceed with DATE TIME SET or
press the reset button to rid the unit of all data and start
fresh. (See page 1 — clear all memory.) Use a ballpoint
pen or end of a paper clip. Press gently.

Move the SET/RUN switch to the SET position. Be sure
battery switch is on.

YEAR DATE TIME SET

Press MODE SELECT until YEAR DATE TIME LED is lit
constantly (no flashing). The colon will be flashing and 4
zeros (00:00) will be displayed. Sequence of entries should
be: YEAR, MONTH/DATE, TIME. Each one is considered a
partial entry — together, they constitute a complete entry.
