Things you should know about programming events:
You can repeat the ON and OFF programming
procedures outlined above for up to seven (7)
events as needed.
NOTE
While setting events, the timer may prematurely turn
on the load, if you press the MODE button.
• Three kinds of settings can cause the timer to
work in an unexpected way:
a. Set up events in progressive order of time, for
example:
8:00 pm ON, 9:00 pm ON, 10:00 pm ON
Not 8:00 pm ON, 10:00 pm ON, 9:00 pm ON
b. Do not overlap event times, for example:
8:00 pm ON / 12:00 pm OFF and
9:00 pm ON / 11:00 pm OFF
c. Set the OFF time for one minute after the ON
time.
Reviewing Events Programmed
In your current time display, press the PROG (program)
button repeatedly to check your settings.
When finished, press the CLOCK button to return the
display to the time of day.
Clearing (Deleting an Event)
1. Press the PROG (program) button as many times
as necessary to locate the setting you want to
clear.
2. Press and hold the MODE button.
3. Press the PROG button to clear the setting.
4. When finished, press the CLOCK button to return
the display to the time of day.
Operating the Time Switch
Press the MODE button repeatedly to set the timer to
Automatic, Random or Manual mode.
NOTE
For the time switch to run programmed events, it
must be set to AUTO mode.
AUTO runs all events automatically according to the
schedule you have set. The word AUTO appears in
the display.
RND (random) runs all events in a RANDOM mode.
This is a security feature in which ON and OFF
times randomly differ +/- 15 minutes from the
programmed times, creating a more “lived-in” look.
The word RND appears on the display.
NOTE
Do NOT set this timer to RND mode. It will not wash
at the exact time you programmed.
MANUAL turns ON and OFF only when the user
presses the ON or OFF button. The display is blank,
showing neither RND or AUTO.
Overriding Timer Settings
The ON or OFF buttons override the current
programmed events. To override the current program
(either ON or OFF), press the ON or OFF button.
