Operation —
All units are shipped from the factory with
the scrolling marquee display, which is located in the main con-
trol box. See Fig. 1. In addition, the
Comfort
Link™ controls
also supports the use of the handheld Navigator™ display.
Both displays provide the user with an interface to the
Comfort
Link control system. The displays have and ar-
row keys, an
key and an
key. These keys
are used to navigate through the different levels of the display
structure. The Navigator and the scrolling marquee operate in
the same manner, except that the Navigator display has multi-
ple lines of display and the scrolling marquee has a single line.
All further discussions and examples in this document will be
based on the scrolling marquee display. See Table 2 for the
menu structure.
The four keys are used to navigate through the display
structure, which is organized in a tiered mode structure. If the
buttons have not been used for a period, the display will default
to the AUTO VIEW display category as shown under the RUN
STATUS category. To show the top-level display, press the
key until a blank display is shown. Then use the
and
arrow keys to scroll through the top-level catego-
ries. These are listed in Appendix A and will be indicated on
the scrolling marquee by the LED next to each mode listed on
the face of the display.
When a specific mode or sub-mode is located, push the
key to enter the mode. Depending on the mode, there
may be additional tiers. Continue to use the and
keys
and the
keys until the desired display item is found.
At any time, the user can move back a mode level by pressing
the
key. Once an item has been selected the display
will flash showing the item, followed by the item value and
then followed by the item units (if any).
Items in the Configuration and Service Test modes are
password protected. The display will flash PASS and WORD
when required. Use the
and arrow keys to enter the
four digits of the password. The default password is 1111.
Pressing the
and
keys simultaneously
will scroll an expanded text description across the display indi-
cating the full meaning of each display point. Pressing the
and
keys when the display is blank
(MODE LED level) will return the display to its default menu
of rotating AUTO VIEW display items. In addition, the
password 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
key to accept
it. Press the
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. 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
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 inter-
face (33PILOT-01) is a component of the 3V™ system and
serves as a user-interface and configuration tool for all Carrier
communicating devices. The System Pilot interface can be
used to install and commission a 3V zoning system, linkage
compatible air source, universal controller, and all other devic-
es operating on the Carrier communicating network.
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. 3 for System Pilot
interface details.
CCN Tables and Display —
In addition to the unit-
mounted scrolling marquee display, the user can also access the
same information through the CCN tables by using the Service
Tool or other CCN programs. Details on the CCN tables are
summarized 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 CCN tables in Appendix B.
GENERIC 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 GENERIC points table. Each one of these place-
holders allows the input of an 8-character ASCII string. 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 enter-
ing point names, download the table to the rooftop unit control.
