Table 4 — ICVC Display Data
1. Only 12 lines of information appear on the chiller display screen
at any one time. Press the or softkey to
highlight a point or to view items below or above the current
screen. Double click the softkey to page forward; press
the softkey twice to page back.
2. To access the information shown in Examples 10 through 24,
enter a 4-digit password after pressing the softkey. If
no softkeys are pressed for 15 minutes, the ICVC automatically
logs off (to prevent unrestricted access to PIC III controls) and
reverts to the default screen. If this happens, re-enter the pass-
word to access the tables shown in Examples 10 through 24.
3. Terms in the Description column of these tables are listed as
they appear on the chiller display screen.
4. The ICVC may be configured in English or Metric (SI) units using
the ICVC CONFIGURATION screen. See the Service Operation
section, page 56, for instructions on making this change.
5. The items in the Reference Point Name column do not appear on
the chiller display screen. They are data or variable names used
in CCN or Building Supervisor (BS) software. They are listed in
these tables as a convenience to the operator if it is necessary to
cross reference CCN/BS documentation or use CCN/BS pro-
grams. For more information, see the 19XRV CCN literature.
6. Reference Point Names shown in these tables in all capital let-
ters can be read by CCN and BS software. Of these capitalized
names, those preceded by a dagger (†) can also be changed
(that is, written to) by the CCN, BS, and the ICVC. Capitalized
Reference Point Names preceded by two asterisks (**) can be
changed only from the ICVC. Reference Point Names in lower
case type can be viewed by CCN or BS only by viewing the
whole table.
7. Alarms and Alerts: An asterisk (*) in the far right field of a ICVC
status screen indicates that the chiller is in an alarm state; an
exclamation point (!) in the far right field of the ICVC screen indi-
cates an alert state. The * (or !) indicates that the value on that
line has exceeded (or is approaching) a limit. For more informa-
tion on alarms and alerts, see the Alarms and Alerts section,
page 19.

EXAMPLE 1 — CHILLER DISPLAY DEFAULT SCREEN
The following data is displayed in the Default screen.
NOTE: The last three entries are used to indicate operating mode to the PIC III. These values may be forced by the ICVC only.
IMPORTANT: The following notes apply to all Table 4
examples.
