Holiday Scheduling; Daylight Saving Time Configuration; Start-Up/Shutdown/Recycle; Sequence - Carrier AquaEdge 19XR series Start-Up, Operation And Maintenance Instructions Manual

holidays as configured in the local chiller's control will be ap-
plied. If a network is present and one time broadcaster on the
network has been enabled, current time and date, DST, and hol-
iday schedules as configured in the controls of the designated
time broadcaster will be applied to all CCN devices (including
chillers) on the network.
HOLIDAY SCHEDULING (FIG. 30) — Up to 18 different
holidays can be defined for special schedule consideration.
There are two different screens to be configured. First, in the
SERVICE / EQUIPMENT CONFIGURATION / HOLIDAYS
screen, select the first unused holiday entry (HOLDY01S, for
example). As shown in Fig. 30, enter a number for Start Month
(1 = January, 2 = February, ..., 12 = December), a number for
Start Day (1 - 31), and Duration in days (0 - 99). By default
there are no holidays set up. Second, in the occupancy Schedule
tables, specify and enable (by setting "X" under the "H" col-
umn) run time period(s) which will apply to all holidays. (Refer
to Fig. 20.) A run time period which is enabled for holidays may
be applied to one or more non-holiday days of the week as well.
This may be done for the local (table OCCPC01S), Ice Build
(OCCPC02S), and/or CCN (OCCPC03S) schedule(s). If the
chiller is on a CCN network, the active holiday definition will
be that configured in the device designated at the sole time
broadcaster (if one is so enabled). See the TIME BROADCAST
ENABLE section.
The broadcast function must be activated for the holidays
configured on the HOLIDEF screen to work properly. Access
the BRODEF screen from the EQUIPMENT CONFIGURA-
TION table and select ENABLE to activate function. Note that
when the chiller is connected to a CCN Network, only one
chiller or CCN device can be configured as the broadcast de-
vice. The controller that is configured as the broadcaster is the
device responsible for transmitting holiday, time, and daylight-
savings dates throughout the network.
To access the BRODEF screen, see the SERVICE menu
structure, Fig. 21.

DAYLIGHT SAVING TIME CONFIGURATION — The
BRODEF table also defines Daylight Saving Time changes.
This feature is by default enabled, and the settings should be
reviewed and adjusted if desired. The following line-item
entries are configurable for both Daylight Savings Time
"Start" and "Stop," and they are defined in Table 8.
To disable the Daylight Savings Time function simply enter
0 minutes for "Start Advance" and "Stop Back."

unit has been without power less than 20 minutes. See the
Auto Restart After Power Failure section. Local start-up (or a
manual start-up) is initiated by pressing the
softkey on the default ICVC screen. Local start-up can proceed
when the chiller schedule indicates that the CURRENT TIME
and CURRENT DATE have been established as a run time
and date, and after the internal 15-minute start-to-start and the
1-minute stop-to-start inhibit timers have expired. These timers

1 = Monday,..., 7 = Sunday
1 = first occurrence of selected
Day of Week in the selected
month, 2 = second occurrence
of the selected Day, etc. This is
not necessarily what one would
conclude from looking at a
standard calendar. For example,
April 7, 2011, is Day 4 Week 1,
but April 8, 2011, is Day 5
Week 2.

"Advance" occurs first in the
year, setting the time ahead by
the specified number of minutes
on the selected date. "Back"
sets the time back by the speci-
fied amount (later in the year).
