of rotating AUTO VIEW display items. In addition, the pass-
word will need to be entered again before changes can be made.
Changing
item values or testing outputs is accomplished
in
the same manner. Locate and display the desired item. If the
display is in rotating auto-view, press the _
key to stop
the display at the desired item. Press the _
key again so
that the item value flashes. Use the arrow keys to change the
value of state of an item and press the _

will resume. Repeat the process as required for other items.
If the user needs to force a variable, follow the same process
as when editing a configuration
parameter.
A forced variable
will be displayed
with a blinking "f' following
its value. For
example, if supply fan requested (FAN.F) is forced, the display
shows "YESf',
where the "f' is blinking to signify a force on
the point. Remove the force by selecting the point that is forced
with the _
key and then pressing the [_
and [_
ar-
row keys simultaneously.
Depending
on the unit model, factory-installed
options and
field-installed
accessories,
some of the items in the various
Mode categories may not apply.
System
Pilot
TM
Interface
E
The
System
Pilot
(33PILOT-01)
device is a component
of Carrier's
3V rM system
and serves as a user-interface
and configuration
tool for all Car-
rier COlrnnunicating
devices. The System Pilot device can be
used to install and COlmnission a 3V zoning system, linkage
compatible
air source, universal
controller, and all other devic-
es operating on the CCN system.
Additionally,
the System
Pilot
device
can serve
as a
wall-lnounted
telnperamre
sensor
for
space
telnperamre
measurement.
The occupant can use the System Pilot device to
change set points. A security feature is provided
to limit access
of features for unauthorized
users. See Fig. 3 for System Pilot
details.
CCN Tables
and
Display
E In addition to the unit-
mounted scrolling marquee display, the user can also access the
same inforlnation through the CCN tables by using the Service
tool or other CCN programs. Details on the CCN tables are
SUlnmarized in Appendix B. The variable names used for the
CCN tables and the scrolling marquee tables may be different
and more items are displayed in the CCN tables. As a refer-
ence, the CCN variable names are included in the scrolling
marquee tables and the scrolling marquee names are included
in the local display tables in Appendix B.

User Interface
GENERICS STATUS DISPLAY TABLE -- The GENERICS
points table allows the service/installer the ability to create a
custom table in which up to 20 points from the 5 CCN
categories (Points, Config, Service-Config, Set Point, and
Maintenance) may be collected and displayed.
In the Service-Config table section, there is a table named
"generics". This table contains placeholders for up to 20 CCN
point names and allows the user to decide which points are dis-
played in the GENERICS points table under the local display.
Each one of these placeholders allows the input of an 8-character
ASCII string. Using a CCN interface, enter the Edit mode for the
Service-Config table "generics" and enter the CCN name for
each point to be displayed in the custom points table in the order
they will be displayed. When done entering point names, down-
load the table to the rooftop unit control.
IMPORTANT:
The
computer
system
software
(ColnfortVIEW
TM,
Service
Tool, etc.) that is used to
interact with CCN controls
always saves a template
of
items it considers
as static (e.g., limits, units, forcibil-
ity, 24-character
text strings,
and point
names)
after
the software
uploads
the tables from a control.
There-
after, the software
is only concerned
with run time
data like value and hardware/force
stares. With this in
mind, it is important
that anytime
a change is made to
the Service-Config
table
"generics"
(which
in turn
changes
the points
contained
in the GENERICS
point
table), that a complete
new upload be performed.
This
requires
that
any
prex4ous
table
database
be
completely
removed
first. Failure to do this will not
allow the user to display the new points that have been
created
and the CCN
interface
will have a different
table database
than the unit control.
