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
support 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
arrow keys, an
key and an
key. These
keys are used to navigate through the different modes of the
display structure. The Navigator and the scrolling marquee dis-
plays operate in the same manner, except that the Navigator
display has multiple 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
categories (modes). 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 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
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
(33PILOT-01) device is a component of Carrier’s 3V™ system
and serves as a user-interface and configuration tool for all Car-
rier communicating devices. The System Pilot device 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 CCN system.
Additionally, the System Pilot device can serve as a
wall-mounted temperature sensor for space temperature
measurement. The occupant can use the System Pilot device to
change setpoints. A security feature is provided to limit access
of features for unauthorized users. See Fig. 3 for System Pilot
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 local display tables in Appendix B.
