Service Operation — An overview of the tables and screens available for the SERVICE function is shown in Fig. 18.

TO ACCESS THE SERVICE SCREENS — When the SER- VICE screens are accessed, a password must be entered.

1.From the main MENU screen, press the SERVICE softkey. The softkeys now correspond to the numerals 1, 2, 3, 4.

2.Press the four digits of the password, one at a time. An asterisk (*) appears as each digit is entered

NOTE: The initial factory-set password is 1-1-1-1. If the password is incorrect, an error message is displayed

If this occurs, return to Step 1 and try to access the SER- VICE screens again. If the password is correct, the soft- key labels change to:

NOTE: The SERVICE screen password can be changed by entering the CVC/ICVC CONFIGURATION screen under SERVICE menu. The password is located at the bottom of the menu.

The CVC/ICVC screen displays the following list of available SERVICE screens:

•Alarm History

•Control Test

•Control Algorithm Status

•Equipment Configuration

•ISM (Starter) Config Data

•Equipment Service

•Time and Date

•Attach to Network Device

•Log Out of Device

•CVC/ICVC Configuration

See Fig. 18 for additional screens and tables available from

the SERVICE screens listed above. Use the EXIT softkey to return to the main MENU screen.

NOTE: To prevent unauthorized persons from accessing the CVC/ICVC service screens, the CVC/ICVC automatically signs off and password-protects itself if a key has not been pressed for 15 minutes. The sequence is as follows. Fifteen minutes after the last key is pressed, the default screen dis- plays, the CVC/ICVC screen light goes out (analogous to a screen saver), and the CVC/ICVC logs out of the password- protected SERVICE menu. Other screen and menus, such as the STATUS screen can be accessed without the password by pressing the appropriate softkey.

TO LOG OUT OF NETWORK DEVICE — To access this screen and log out of a network device, from the default CVC/

ICVC screen, press the MENU and SERVICE softkeys. Enter the password and, from the SERVICE menu, highlight

LOG OUT OF NETWORK DEVICE and press the SELECT softkey. The CVC/ICVC default screen will now be displayed.

HOLIDAY SCHEDULING (Fig. 25) — The time schedules may be configured for special operation during a holiday peri- od. When modifying a time period, the “H” at the end of the days of the week field signifies that the period is applicable to a holiday. (See Fig. 19.)

The broadcast function must be activated for the holidays configured on the HOLIDEF screen to work properly. Access the BRODEF screen from the EQUIPMENT CONFIGURA- TION table and select ENABLE to activate function. Note that when the chiller is connected to a CCN Network, only one chiller or CCN device can be configured as the broadcast de- vice. The controller that is configured as the broadcaster is the device responsible for transmitting holiday, time, and daylight- savings dates throughout the network.

To access the BRODEF screen, see the SERVICE menu structure, Fig. 18.

To view or change the holiday periods for up to 18 different holidays, perform the following operation:

1.At the Menu screen, press SERVICE to access the Ser- vice menu.

2.If not logged on, follow the instructions for Attach to Net- work Device or To Log Out. Once logged on, press

NEXT until Equipment Configuration is highlighted.

3.Once Equipment Configuration is highlighted, press SELECT to access.

4.Press NEXT until HOLIDAYS is highlighted. This is the Holiday Definition table.

5.Press SELECT to enter the Data Table Select screen. This screen lists 18 holiday tables.

6. Press NEXT to highlight the holiday table that is to be viewed or changed. Each table is one holiday period, starting on a specific date, and lasting up to 99 days.

7.Press SELECT to access the holiday table. The Config- uration Select table now shows the holiday start month and day, and how many days the holiday period will last.

8.Press NEXT or PREVIOUS to highlight the month, day, or duration.

9.Press SELECT to modify the month, day, or duration.

10.Press INCREASE or DECREASE to change the selected value.

11.Press ENTER to save the changes.

12.Press EXIT to return to the previous menu.
