INPUT THE LOCAL OCCUPIED SCHEDULE — Access
the schedule screen and set up the occupied time schedule ac-
cording to the customer’s requirements. If no schedule is avail-
able, the default is factory set for 24 hours occupied, 7 days per
week including holidays. The Schedule Menu as well as the
Holiday Menu can be reached through the Configuration
Menu. When the control mode is LOCAL SCHEDULE, the
chiller will be automatically started if the configured local
schedule is occupied and will be automatically shut down by
the unoccupied schedule.
The Network Schedule should be configured if a CCN sys-
tem is being installed. When control mode is NETWORK, the
chiller can be started and stopped by the CHIL_S_S software
point as written by other equipment through the network com-
mand and network schedule.
For more information about setting time schedules, please
refer to the PIC5 Control User Manual.

19DV Configuration Tables. For specific values for the fol-
lowing configurations, refer to the chiller performance data or
job-specific data sheet:
1. Password
2. Log in/log out
3. Input time and date
4. Service parameters
5. Equipment configuration

PASSWORD — PIC5 provides a smart factory password for
better security and the password changes periodically. With a
smart password, only authorized users can log into the control-
ler factory tables to access key product configuration and main-
tenance data.
A password must be entered to access the Set Point or other
common user tables. See Fig. 27. User password can be
changed from the General Configuration Menu. USER CON-
FIGURATION allows change of the User access password.
IMPORTANT: Be sure to remember the password.
Retain a copy for future reference. Without the pass-
word, access will not be possible unless accessed by a
Carrier representative. Factory password is required to
enter configuration menus required for chiller setup.
