duration, then press OK. Remember INTVL or PULSE override 
is initiated on demand via the keypad and is not based on a day
and time, as is normal INTVL or PULSE. To initiate an override
interval or pulse first set the RUN/SET switch to RUN and set the
switch for the desired load to Enable, then press the ON/OFF key
for the load you wish to override. The green load indicator flashes
during the interval or pulse to show override selection. At the end
of an override interval or override pulse, the load and green LED
will turn off, unless a programmed ON event has occurred during
the override time period. This allows the override interval to be
used as an “early ON” as well as a “late OFF” override after
normal hours of operation without interfering with normal
scheduled ON/OFF times. 

The load will respond to any subsequent program schedules. You
may also initiate an override interval or pulse by pressing and
holding the INTVL key, then pressing the ON/OFF key for the
Enabled

circuit you wish to override. This allows an override to be

started without turning off a load that is already on. This is useful
for HID lighting applications where even a brief turn off will
cause loss of lighting for several minutes. Note that override can
only be set for an interval or pulse, not both.

An override interval or pulse may be ended early only by pushing
the ON/OFF key or by a power interruption. Thus, a
programmed OFF event will not end an override interval or pulse.
At the same time, any ON or OFF events which occurred during
the override period will be in effect at the completion of the
override time period. This allows applications such as a
programmed ON time of 8:00 A.M. with a 2 hour interval
override initiation at 7:30 A.M. At 9:30 A.M., after the two hour
override, the lights will remain ON since during the override
period they were programmed to switch ON (at 8:00 A.M.). 
The override pulses are precise to-the-second whereas override
interval duration is the program duration ± 30 seconds, dependent
on the instant in time when the override was initiated. 

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. If ASTRO is pressed during the “Switch On” prompt, the
timer prompts for sunset. If ASTRO is pressed during the “Switch
Off

” prompt, the timer prompts for sunrise. For applications

requiring an ON event at sunrise and/or an OFF event at sunset,
press AM or PM respectively to toggle the sunrise/sunset prompts.

Interval programming may be used to extend the “Switch On”
and “Switch Off” times of ASTRO schedules. This is useful when
some circuits require differing offsets from the ASTRO ON/OFF
times that were entered during SET UP. To use this feature, enter
the earliest required ASTRO ON/OFF times during SET UP,
then use intervals of various durations to delay the ON/OFF times
as required. Specifically, use an ON interval to delay an ASTRO
turn OFF time and use an OFF interval to delay an ASTRO turn
ON time. Refer to the “Programming Examples” booklet for
detailed instructions. 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 (DST) 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 A.M. Due to unexpected
results, it is recommended you do not attempt programming from
12:00 midnight to 2:00 A.M. on these two days.)
