IMPORTANT: The following notes apply to all Table 3
examples.
1. Only 1 lines of information appear on the ICVC
screen at any one time. Press the
neXt
or
pReVIoUS
softkey to highlight a point or to view items below or
above the current screen. Double-click the
neXt
softkey to page forward; double-click the
pReVIoUS
softkey to page back.
. To access the information shown in examples 10 to ,
enter a 4-digit password after pressing the
SeRVICe
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 password to access
the tables shown in Examples 10 to .
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 49, 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
programs. For more information, see the 19XRV CCN
literature.
Table 3 - ICVC display data
6. Reference Point Names shown in these tables in all
capital letters can be read by CCN and BS software.
Of these capitalised names, those preceded by a dagger
(†) can also be changed (that is, written to) by the CCN,
BS and the ICVC. Capitalised 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 an ICVC status screen indicates that the chiller is in
an alarm state; an exclamation mark (!) in the far right
field of the ICVC screen indicates an alert state. The
asterisk (or exclamation point) indicates 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 14.
