show the top-level display, press the ESC key until a blank dis
-
play is shown. Then use the
and
keys to scroll through
the top level categories.These are listed in Appendix A and will
be indicated on the Navigator by the LED next to each mode list
-
ed on the face of the display.
When a specific mode or sub-mode is located, push the
ENTER key to enter the mode. Depending on the mode, there
may be additional tiers. Continue to use
and
keys and
the ENTER key until the desired display item is found. At any
time, the user can move back a mode level by pressing the ESC
key.
Items in the Configuration and Service Test modes are pass
-
word protected. The display will prompt for a PASSWORD.
Use the ENTER and arrow keys to enter the 4 digits of the
password. The default password is 1111.
Pressing the ESC and ENTER keys simultaneously will dis
-
play an expanded text description for each display point.
Changing item values or testing outputs is accomplished in the
same manner. Locate and display the desired item. If the dis
-
play is in rotating auto-view, press the ENTER key to stop the
display at the desired item. Press the ENTER key again so that
the item value flashes. Use the arrow keys to change the value
or state of an item and press the ENTER key to accept it. Press
the ESC key and the item, value, or units display 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. When using the Navi
-
gator display, a forced variable will be displayed with a blink
-
ing “f” following its value. For example, if supply fan request
-
ed (
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 ENTER key and then
pressing both arrow 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™ Interface
The System Pilot interface (33PILOT-01) is a component of
the Carrier 3V™ system and can serve as a CCN user-interface
and configuration tool.
Additionally, the System Pilot interface can serve as a wall-
mounted temperature sensor for space temperature measure
-
ment. The occupant can use the System Pilot interface to
change set points. A security feature is provided to limit access
of features for unauthorized users. See Fig. 2 for System Pilot
interface details.
CCN Tables and Display
In addition to the Navigator display, the user can also access
the same information through the CCN tables by using the Sys
-
tem Pilot, Service Tool, or other CCN programs. Details on the
CCN tables are summarized in Appendix B. The point names
displayed in the CCN tables and the corresponding local dis
-
play acronyms available via the Navigator display may be dif
-
ferent and more items are displayed in the CCN tables. As a
reference, the CCN point names are included in the local dis
-
play menus shown in Appendix A.
GENERIC STATUS DISPLAY TABLE
The GENERIC points table allows the service/installer the ability
to create a custom table in which up to 20 points from the 5 CCN
categories (Status, Config/Service-Config, Set Point, Mainte
-
nance, and Occupancy) may be collected and displayed.
In the Service-Config table section, there is a table named “ge
-
nerics.” This table contains placeholders for up to 20 CCN
point names and allows the user to decide which points are dis
-
played in the GENERIC points table. Each one of these place-
holders allows the input of an 8-character ASCII string.
Using a CCN method of interface, go into 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,
download the table to the rooftop unit control.

System Pilot User Interface
IMPORTANT: The computer system software (Comfort
-
VIEW™, 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, forcibility, 24-character text
strings, and point names) after the software uploads the ta
-
bles from a control. Thereafter, the software is only con
-
cerned with run time data like value and hardware/force sta
-
tus. 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 GENERIC point ta
-
ble), a complete new upload is performed.
This requires
that any previous 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 software will
have a different table database than the unit control.
