To Change The Password; To Change Display To Metric Units; Change Language; Change Cvc/Icvc Configuration - Carrier 19XR User Manual

NOTE: Because a schedule is integral to the chiller control
sequence, the chiller will not start until the time and date have
been set.
CHANGE CVC/ICVC CONFIGURATION IF NECES-
SARY — From the SERVICE table, access the CVC/ICVC
CONFIGU-RATION screen. From there, view or modify the
CVC/ICVC CCN address, change to English or SI units, and
change the password. If there is more than one chiller at the
jobsite, change the CVC/ICVC address on each chiller so that
each chiller has its own address. Note and record the new
address. Change the screen to SI units as required, and change
the password if desired.
TO CHANGE THE PASSWORD — The password may be
changed from the CVC/ICVC CONFIGURATION screen.
1. Press the and
MENU
current password and highlight CVC/ICVC CONFIGU-
RATION. Press the
SELECT
5 entries on the CVC/ICVC CONFIG screen can be
changed: BUS #, ADDRESS #, BAUD RATE, US IMP/
METRIC, and PASSWORD.
2. Use the softkey to scroll to PASSWORD. The
ENTER
first digit of the password is highlighted on the screen.
3. To change the digit, press the
softkey. When the desired digit is seen,
DECREASE
press the softkey.
ENTER
4. The next digit is highlighted. Change it, and the third and
fourth digits in the same way the first was changed.
5. After the last digit is changed, the CVC/ICVC goes to the
BUS parameter. Press the
screen and return to the SERVICE menu.
Be sure to remember the password. Retain a copy
for future reference. Without the password, access to the
SERVICE menu will not be possible unless the CVC/
ICVC_PSWD menu on the STATUS screen is accessed by
a Carrier representative.
TO CHANGE THE CVC/ICVC DISPLAY FROM
ENGLISH TO METRIC UNITS — By default, the CVC/
ICVC displays information in English units. To change to met-
ric units, access the CVC/ICVC CONFIGURATION screen:
1. Press the and
MENU
password and highlight CVC/ICVC CONFIGURATION.
Press the softkey.
SELECT
2. Use the softkey to scroll to US IMP/METRIC.
ENTER
3. Press the softkey that corresponds to the units desired for
display on the CVC/ICVC (e.g., US or METRIC).
CHANGE LANGUAGE (ICVC Only) — By default, the
ICVC displays information in English. To change to another
Language, access the ICVC CONFIGURATION screen:
1. Press the and
MENU
password and highlight ICVC CONFIGURATION. Press
the softkey.
SELECT
2. Use the softkey to scroll to LID LANGUAGE.
ENTER
3. Press the INCREASE or DECREASE softkey until the
desired language is displayed. Press
desired language.
MODIFY CONTROLLER IDENTIFICATION IF NECES-
SARY — The CVC/ICVC module address can be changed
from the CVC/ICVC CONFIGURATION screen. Change this
softkeys. Enter the
SERVICE
softkey. Only the last

address for each chiller if there is more than one chiller at the
jobsite. Write the new address on the CVC/ICVC module for
future reference.

NOTE: Other parameters: Screens are normally left at the default settings; they
may be changed by the operator as required. The time and persistence set-
tings on the ISM_CONF table can be adjusted to increase or decrease the sen-
sitivity to a fault condition. Increasing time or persistence decreases sensitivity.
Decreasing time or persistence increases sensitivity to the fault condition.
