Table 2 — CVC Display Data

1. Only 12 lines of information appear on the CVC 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.

2. To access the information shown in Examples 10 through 22,

enter your 4-digit password after pressing the soft-

key. If no softkeys are pressed for 15 minutes, the CVC automat-

ically 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 22.

3. Terms in the Description column of these tables are listed as

they appear on the CVC screen.

4. The CVC may be configured in English or Metric (SI) units using

the CVC CONFIGURATION screen. See the Service Operation

section, page 45, for instructions on making this change.

5. The items in the Reference Point Name column

do not appear on

the CVC 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.

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 CVC. Capitalized Refer-

ence Point Names preceded by two asterisks can be changed

only from the CVC. 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 CVC

status screen

indicates that the chiller is in an alarm state; an

exclamation point in the far right field of the CVC screen indi-

cates 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 15.
