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 MENU and SERVICE softkeys. Enter the current password and highlight CVC/ICVC CONFIGU-

RATION. Press the SELECT softkey. Only the last 5 entries on the CVC/ICVC CONFIG screen can be changed: BUS #, ADDRESS #, BAUD RATE, US IMP/ METRIC, and PASSWORD.

2.Use the ENTER softkey to scroll to PASSWORD. The first digit of the password is highlighted on the screen.

3.To change the digit, press the INCREASE or DECREASE softkey. When the desired digit is seen, press the ENTER softkey.

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 EXIT softkey to leave that 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 MENU and SERVICE softkeys. Enter the password and highlight CVC/ICVC CONFIGURATION. Press the SELECT softkey.

2.Use the ENTER softkey to scroll to US IMP/METRIC.

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 MENU and SERVICE softkeys. Enter the password and highlight ICVC CONFIGURATION. Press the SELECT softkey.

2.Use the ENTER softkey to scroll to LID LANGUAGE.

3.Press the INCREASE or DECREASE softkey until the

desired language is displayed. Press ENTER to confirm desired language.

MODIFY CONTROLLER IDENTIFICATION IF NECES- SARY — The CVC/ICVC module address can be changed from the CVC/ICVC CONFIGURATION screen. Change this

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.

INPUT EQUIPMENT SERVICE PARAMETERS IF NEC- ESSARY — The EQUIPMENT SERVICE table has six service tables.

Configure SERVICE Tables — Access the SERVICE tables, shown in Table 2, to modify or view job site parameters:
