Table 3 — ICVC Display Data
1. The Display data shown applies to ICVC software version 14.
2. 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. Press the softkey twice to page forward; press
the softkey twice to page back.
3. To access the information shown in Examples 10 through 25,
enter your 4-digit password after pressing the soft-
key. If no softkeys are pressed for 15 minutes, the ICVC auto-
matically logs off (to prevent unrestricted access to PIC II
controls) and reverts to the default screen. If this happens, you
must re-enter your password to access the tables shown in
Examples 10 through 25.
4. Terms in the Description column of these tables are listed as
they appear on the chiller display screen.
5. The ICVC may be configured in English or Metric (SI) units
using the ICVC CONFIGURATION screen. See the Service
Operation section, page 63, for instructions on making this
change.
6. 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 programs. For more information, see the 19XR CCN
literature.
7. 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.
8. 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 asterisk (or exclamation point) indi-
cates that the value on that line has exceeded (or is
approaching) a limit. For more information on alarms and
alerts, see the Alarms and Alerts section, page 22.
9. Index of all ICVC parameters is shown in Appendix A.
10. An abbreviation in the column to the right of POINT STATUS,
indicates that the point is being Forced and the Force level. The
CCN Force priority hierarchy is found in ICVC OPERATION
AND MENUS. (This does not apply to the DEFAULT screen).
LEGEND
EXAMPLE 1 — CHILLER DISPLAY DEFAULT SCREEN
The following data is displayed in the Default screen.
NOTES:
1. The Evaporator Refrigerant Temperature displayed is the
smaller value of EVAP REFRIG LIQUID TEMP or CALC EVAP
SAT TEMP.
2. The last three entries are used to indicate operating mode to
the PIC II. These values may be forced by the ICVC only.
