Variable Air Volume
The A Series units provide ventilation, cooling, and heating
(when equipped) in variable air volume (VAV), variable volume
and temperature (VVT(R)), and constant volume (CV) applica-
tions. The A Series units contain the factory-installed
(_mfortLink TM control system which provides full system
management. The main base board (MBB) stores hundreds of
unit configuration settings and 8 time of day schedules. The
MBB also performs self diagnostic tests at unit start-up, moni-
tors the operation of the unit, and provides alarms and alert in-
formation. The system also contains other optional boards that
are connected to the MBB through the Local Equipment Net-
work (LEN). Information on system operation and stares are
sent to the MBB processor by various sensors and optional
boards that are located at the unit. Access to the unit controls for
configuration, set point selection, schedule creation, and service
can be done through a unit-mounted scrolling marquee. Access
can also be done through the Carrier Comfort Network R>(CCN)
system using the ComfortVIEW rM software, the accessory
Navigator TM hand-held display, or the System Pilot TM interface.
The (_nfortLink system controls all aspects of the rooftop.
It controls the supply-fan motor, compressors, and economiz-
ers to maintain the proper temperature conditions. The controls
also cycle condenser fans to maintain suitable head pressure.
All VAV units are equipped with a standard VFD (variable fre-
quency drive) for supply fan speed control and supply duct
pressure control. The (_mfortLink controls adjust the speed of
the VFD based on a static pressure sensor input. In addition,
the (_mfortLink controls can raise or lower the building pres-
sure using multiple power exhaust fans controlled from econo-
mizer damper position or from a building pressure sensor. The
control safeties are continuously monitored to ensure safe oper-
ation under all conditions. Sensors include suction pressure
transducers, discharge pressure transducers, and saturated con-
densing temperature sensors which allow for display of opera-
tional pressures and saturation temperatures.
A scheduling function, prograimned by the user, controls
the unit occupied/unoccupied schedule. Up to 8 different
schedules can be progralmned.
The controls also allow the service person to operate a quick
test so that all the controlled components can be checked for
proper operation.
Conventions Used in This Manual EThe follow-
ing conventions for discussing configuration points for the lo-
cal display (scrolling marquee or Navigator accessory) will be
used in this manual.
Point names will be written with the Mode name first, then
any sub-modes, then the point name, each separated by an
arrow symbol (--->). Names will also be shown in bold and
italics. As an example, the IAQ Economizer Ovemde Position
which is located in the Configuration mode, Indoor Air Quality
Configuration sub-mode, and the Air Quality Set Points
sub-sub-mode, would be written as (bnfiguration--€
IAQ---_IAQ.SP-_IQ.O.P. A list of point names can be found in
Appendix A.
This path name will show the user how to navigate through
the local display to reach the desired configuration. The user
would scroll through the modes and submodes using the
[] and _--] keys. The arrow symbol in the path name repre-
sents pressing _ to move into the next level of the
menu structure.
When a value is included as part of the path name, it will be
shown at the end of the path name after an equals sign. If the
value represents a configuration setting, an explanation will be
shown in parentheses after the value. As an example, Configu-
ration--+IAQ---)AQ. CF--+IQ.AC =1(IAQ Analog Input).
Pressing the _ and _ keys simultaneously
at any thne will display an expanded text description of the four-
character point name. The expanded description is shown in the
local display tables (Appendix A).
The CCN point names are also referenced in the local
display tables for users configuring the unit with CCN software
instead of the local display. The CCN tables are located in
Appendix B of this manual.
BASIC CONTROL USAGE
ComfortLink Controls EThe (_mfortLink control
system is a comprehensive unit-management system. The con-
trol system is easy to access, configure, diagnose and trouble-
shoot.
The control is flexible, providing two types of constant
volume cooling control sequences, two variable air volume
cooling control sequences, and heating control sequences for
two-stage electric and gas systems, and for multiple-stage gas
heating, in both Occupied and Unoccupied schedule modes.
This control also manages:
• VAV duct pressure (through optional VFD), with reset
• Building pressure through two different power exhaust
schemes
• Condenser fan cycling for mild ambient head pressure
control
• Space ventilation control, in Occupied and Unoccupied
periods, using CO2 sensors or external signals, with ven-
tilation defined by damper position
• Smoke control functions
• Occupancy schedules
• Occupancy or start/stop sequences based on third party
signals
• Alarm status and history and run time data
• Management of a complete unit service test sequence

atthe opposite end of the unit, at a remote modular plug. The
Navigator display provides the same menu structure, control
access and display data as is available at the unit-mounted
scrolling marquee display.
Scrolling Marquee -- This device is the standard inter-
face used to access the control information, read sensor values,
and test the unit. The scrolling marquee is located in the main
control box. The scrolling marquee display is a 4-key, 4-char-
acter LED (light-emitting diode) display module. The display
also contains an Alarm Stares LED. See Fig. 1. The display is
easy to operate using 4 buttons and a group of 11 LEDs that in-
dicate the following menu structures, referred to as modes (see
Appendix A):
•Run Status
• Service Test
• Temperatures
• Pressures
• Set points
• Inputs
• Outputs
• Configuration
• Timeclock
• Operating Modes
• Alarms
Through the scrolling marquee, the user can access all of the
inputs and outputs to check on their values and status, config-
ure operating parameters plus evaluate the current decision sta-
res for operating modes. Because the A Series units are
equipped with suction pressure and saturated condensing
temperature transducers, the scrolling marquee can also display
refrigerant circuit pressures typically obtained from service
gages. The control also includes an alarm history which can be
accessed from the display. In addition, through the scrolling
O Alarms ©_
Fig. 1 -- Scrolling Marquee
Fig. 2 -- Accessory Navigator Display
marquee, the user can access a built-in test routine that can be
used at start-up colrunissioning to diagnose operational prob-
lems with the unit.
Accessory Navigator TM Display-- The accessory
hand-held Navigator display can be used with the A Series
units. See Fig. 2. The Navigator display operates the same way
as the scrolling marquee device. The Navigator display is
plugged into the RJ-14 (LEN) jack in the main control box on
the COMM board. The Navigator display can also be plugged
into the RJ-14 jack located on the ECB (economizer control
board) located in the auxiliary control box.
Operation -- All units are shipped from the factory with
the scrolling marquee display, which is located in the mare con-
trol box. See Fig. 1. In addition, the (_n?fortLink TM controls
also support the use of the handheld Navigator display.
Both displays provide the user with an interface to the
(_n_fortLink control system. The displays have [] and []
arrow keys, an IESCAPEI key and an _ key. These
keys are used to navigate through the different modes of the
display structure. The Navigator and the scrolling marquee op-
erate 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
]ESCAPE] 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 ]ESCAPE] key. Once an item has been selected the display

f "-,
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 IESCAPEI and _ keys simultaneously
will scroll an expanded text description across the display indi-
cating the full meaning of each display point. Pressing the
IESCAPEI 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 ]ESCAPE] 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 [_ 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 PilotTM Interface E The System Pilot
(33PILOT-01) device is a component of Carrier's 3V rMsystem
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.

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 forthe
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.

START-UP
IMPORTANT: Do not attempt to start unit, even
momentarily, until all items on the Start-Up Checklist
and the following steps have been completed.
Unit Preparation ECheck that unit has been installed in
accordance with the installation instructions and applicable
codes.
Unit Setup EMake sure that the economizer hoods have
been installed and that the outdoor filters are properly installed.
Internal Wiring _Ensure that all electrical connections
in the control box are tightened as required. If the unit has
staged gas heat make sure that the leaving air temperature
(LAT) sensors have been routed to the supply ducts as required.
Accessory Installation -- Check to make sure that all
accessories including space thermostats and sensors have been
installed and wired as required by the instructions and unit
wiring diagrams.
Crankcase Heaters -- Crankcase heaters are energized
as long as there is power to the unit, except when the compres-
sors are running.
IMPORTANT: Unit power must be on for 24 hrs prior
to start-up of compressors. Otherwise damage to com-
pressors may result.
Evaporator Fan -- Fan belt and fixed pulleys are factory-
installed. See Tables 3-38 for fan performance. Remove tape
from fan pulley, and be sure that fans rotate in the proper direc-
tion. See Table 39 for motor limitations. See Tables 40A and
40B for air quantity limits. Static pressure drop for power
exhaust is negligible. To alter fan performance, see Evaporator
Fan Performance Adjustment section on page 130.
Controls EUse the following steps for the controls:
IMPORTANT: The unit is shipped with the unit control ]
disabled. To enable the control, set Local Machine Disable I
(Service Test-gSTOP) to No.
1. Set any control configurations that are required (field-
installed accessories, etc.). The unit is factory configured
for all appropriate factory-installed options.
2. Enter unit set points. The unit is shipped with the set point
default values. If a different set point is required use the
scrolling marquee, Navigatoff M accessory or Service
Tool software to change the configuration valves.
3. If the internal unit schedules are going to be used config-
ure the Occupancy schedule.
4. Verify that the control time periods progralnmed meet
current requirements.
5. Using Service Test mode, verify operation of all major
components.
6. If the unit is a VAV unit make sure to configure the VFD
static pressure set point using the display. To checkout the
VFD use the VFD instructions shipped with the unit.
Gas Heat -- Verifygas pressure before turning on gas heat
as follows:
1. Turn off field-supplied manual gas stop, located external
to the unit.
2. Connect pressure gages to supply gas tap, located at field-
supplied manual shutoffvalves.
3. Connect pressure gages to manifold pressure tap on unit
gas valve.
4. Supply gas pressure must not exceed 13.5 m. wg. Check
pressure at field-supplied shut-offvalve.
5. Turn on manual gas stop and initiate a heating demand.
Jumper R to Wl in the control box to initiate heat.
6. Use the Service Test procedure to verify heat operation.
7. After the unit has mn for several minutes, verify that
incoming pressure is 6.0 m. wg or greater and that the
manifold pressure is 3.5 in wg. If manifold pressure must
be adjusted refer to Gas Valve Adjustment section.

Bhp -- Brake Horsepower
edb -- Entering Dry Bulb
ewb -- Entering Wet Bulb
NOTES:
1. Fan performance is based on wet coils, economizer, roof curb, cabinet
losses, and clean 2-in. filters.
2. Conversion -- Bhp to watts:
Watts = Bhp x 746
Motor efficiency
3. Variable air volume units will operate down to 70 cfm/ton. Performance at
70 cfm/ton is limited to unloaded operation and may be additionally limited
by edb and ewb conditions.

Bhp x 746
Watts = Motor efficiency
3. Variable air volume units will operate down to 70 cfm/ton. Performance at
70 cfm/ton is limited to unloaded operation and may be additionally limited
by edb and ewb conditions.
