4) Programming SET EVENT: To program the
SET EVENT section, first press the PROG#
button on the Digital Command Center. The
display will flash the current program number
and show the start time of that program. The
program can only be changed while flashing. To
enter a new program, first press the DAY button
in the upper SET EVENT section to choose the
individual day or a block of days (i.e. M-TU-W-
TH-F, or SU-M-TU-W-TH-F-SA). With the
proper day(s) selected, set start time for
program 1 using the upper HOUR and MIN
buttons. Be sure to select the proper AM or PM
hour. Then press the MAX/IDLE/OFF button to
choose the mode for program 1. Program 1 is
complete. Press PROG# button to get to
program 2. Enter the start time of program 2
and select the mode. You are only program-
ming the start time of each program. The end
time is automatically the start time of the next
program. The last program entered is limited to
11:59PM. If the facility operates beyond
midnight, program 1 of the next day must be
set to 12:00 AM for continuous operation.
Follow the same process for all the programs
and days of the week. To exit the programming
mode, press the ENTER button or wait 30
seconds and it will stop blinking and your
changes will be saved. The DIGITAL COM-
MAND CENTER needs a minimum of two
programs per day to function as shown in
EXAMPLE 2. The first must be IDLE or MAX
and the last program must be OFF mode. Note:
Programs 1 through 6 are sequential and
therefore it will not be possible to set a new
program before the end of the previous
program.
(a) Programming Tip: To modify an existing
program press the PROG# button and the
upper DAY button to get to highlight the
program you want to change. Then modify
the setting with the appropriate button.
Entries will be saved automatically in 30
seconds or by pressing the enter button.
(b) Programming Tip: If the facility operates
on nearly the same schedule every day, it
may be easier to program all seven days to
the same common program and then go
back and program Sunday to be off if the
facility is closed that day.
(c) Programming Tip: You can review your
program by pressing the PROG# button
and toggling through the programs and
toggling through the days of the weeks,
and observing the time settings. If you
made no changes simply press the enter
button to return to normal or it will return in
30 seconds.
(d) Programming Tip: When reviewing the
program and a block of days are selected,
if all the individual programs for those days
do not match, the clock will display --:--.
This is normal and any adjustments made
at this time will reprogram all days selected
to match the new entry.
5) Manager lock function: The Digital Command
Center has a locking feature that prevents any
setting to be changed when locked. To lock the
control, press the lock button, the lock icon will
flash for up to 30 seconds. While the icon is
flashing, press any three consecutive buttons,
and then press the lock button again to confirm.
The three consecutive buttons pressed are the
password. The system control will be locked
and the lock icon will be on steady. To unlock,
press the lock button and then press the same
three consecutive buttons as the previous
password, the system will be unlocked and the
lock icon will disappear. If the password is lost
or forgotten, it can be reset. This will require
two people. Turn off the main power (circuit
breaker), have a second person then press and
hold the lock button on the Digital Command
Center while the first person turns the power
back on. The system will be unlocked. Also see
the reset section for an alternate method (step
11).
6) Temporary Mode setting: By pressing
IDLE/MAX/OFF button on the Digital Command
Center you can temporarily change the current
mode (IDLE/MAX/OFF). This is only a tempo-
rary change until the next programmed event.
7) Auto-Blow Down: The optional auto-blow down
becomes active in the OFF mode. When first
entering OFF mode, the steam valves will
deactivate and the generator will continue to
maintain normal pressure. After 5 minutes the
generator will shut down and the drain will
open. Boiling water will exit under pressure and
the water valve will turn on to help flush the
generator. After 2 minutes the drain will close
and the generator will refill. After a total of 7
minutes the generator is ready to start a new
cycle. If the facility is operated 24 hours a day,
a 7 minute OFF mode should be programmed
in to allow for a proper drain cycle. In areas
where the water is hard, a second drain cycle
can be programmed by adding an extra 7
