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.

RECYCLE SEQUENCE (Fig. 30)
Local Start-Up —
Local start-up (or a manual start-up) is
initiated by pressing the menu 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 are represented
in the START INHIBIT TIMER and can be viewed on the
MAINSTAT screen and DEFAULT screen. The timer must ex-
pire before the chiller will start. If the timers have not expired
the RUN STATUS parameter on the MAINSTAT screen now
reads TIMEOUT.
NOTE: The time schedule is said to be “occupied” if the
OCCUPIED ? parameter on the MAINSTAT screen is set to
YES. For more information on occupancy schedules, see the
sections on Time Schedule Operation (page 23), Occupancy
Schedule (page 44), and To Prevent Accidental Start-Up
(page 89), and Fig. 20.
If the OCCUPIED ? parameter on the MAINSTAT screen
is set to NO, the chiller can be forced to start as follows. From
the default ICVC screen, press the and
softkeys. Scroll to highlight MAINSTAT. Press the
softkey. Scroll to highlight CHILLER START/STOP. Press
the softkey to override the schedule and start the
chiller.
NOTE: The chiller will continue to run until this forced start is
released, regardless of the programmed schedule. To release
the forced start, highlight CHILLER START/STOP from the
MAINSTAT screen and press the softkey. This
action returns the chiller to the start and stop times established
by the schedule.
The chiller may also be started by overriding the time
schedule. From the default screen, press the
and softkeys. Scroll down and select the current
