ATTACHING TO OTHER CCN MODULES — If
chiller ICVC has been connected to a CCN Network or other
PIC- controlled chillers through CCN wiring, the ICVC can be
used to view or change parameters on the other controllers.
Other PIC III chillers can be viewed and set points changed (if
the other unit is in CCN control), if desired, from this particular
ICVC module.
If the module number is not valid, the "COMMUNICA-
TION FAILURE" message will show and a new address num-
ber must be entered or the wiring checked. If the module is
communicating properly, the "UPLOAD IN PROGRESS"
message will flash and the new module can now be viewed.
Whenever there is a question regarding which module on
the ICVC is currently being shown, check the device name
descriptor on the upper left hand corner of the ICVC screen.
See Fig. 35.
When the CCN device has been viewed, the ATTACH TO
NETWORK DEVICE table should be used to attach to the PIC
that is on the chiller. Move to the ATTACH TO NETWORK
DEVICE table (LOCAL should be highlighted) and press the
softkey to upload the LOCAL device. The ICVC

may be configured for special operation during a holiday
period. When modifying a time period, the "H" in the far right
column of the OCCPC01S, OCCPC02S or OCCPC03S time
schedule screen signifies that the period is applicable to a
holiday. (See Fig. 29.)
