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. 24-25 for details.) Holidays are entered with 2-digit
reference numbers; a chart for recording the date(s) is located on
page 22. Leap years are preset through the year 2094
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 (2 circuit models only). 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 (2 circuit models only).
5) RUN/SET switch must be returned to RUN position to enable
automatic control and to save changes to data.
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
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 events 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 and PULSE keys include a
temporary override function with a maximum length of 6 days, 23
hrs. and 59 min. for the interval or 127 seconds for the pulse. To
program an interval or pulse for override, select SET, enable the
circuit, press PROG, press INTVL
or PULSE (without selecting a
day), key in the interval or pulse
