The 48/50Z units contain the factory-installed ComfortLink
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, monitors the operation of
the unit, and provides alarms and alert information. The system
also contains other optional boards that are connected to the
MBB through the Local Equipment Network (LEN). Information on system operation and status are sent to the MBB processor by various sensors and optional board that are located at
the unit and in the conditioned space. 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
®
using ComfortVIEW™ software, Network Service
Tool, or the accessory Navigator™ device.
The ComfortLink system controls all aspects of the rooftop.
It controls the supply-fan motor, compressors, and economizers
to maintain the proper temperature conditions. The controls
also cycle condenser fans to maintain suitable head pressure.
All VAV units can be equipped with optional IGV (inlet guide
vanes) or VFD (variable frequency drive) for supply duct pressure control. The ComfortLink™ controls can directly control
the speed of the VFD based on a static pressure sensor input. In
addition the ComfortLink controls can adjust (but not control
on CV and non-modulating power exhaust units) the building
pressure using multiple power exhaust fans controlled from
damper position or from a building pressure sensor. The control
safeties are continuously monitored to prevent the unit from
operating under abnormal conditions. Sensors include suction
pressure transducers and saturated discharge pressure transducers which allow for display of the unit’s operational pressures.
A scheduling function, programmed by the user, controls
the unit occupied/unoccupied schedule. Up to 8 different
schedules can be programmed.
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 — The follow-
ing conventions for discussing configuration points for the local display (scrolling marquee or Navigator™ accessory) will
be used in this manual.
Point names will be written with the Mode name first, then
any submodes, 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 Override 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 Configuration
IAQ→IAQ.SP→IQ.O.P.
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
UP ARROW and DOWN ARROW keys. The arrow symbol
in the path name represents pressing ENTER 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 parenthesis after the value. As an example, Configu-
ration
→
IAQ→AQ.CF→IQ.AC = 1 (IAQ Analog Input).
Pressing the ESCAPE and ENTER keys simultaneously
will scroll an expanded text description of the point name
across the display. The expanded description is shown in the
local display tables but will not be shown with the path names
in text.
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 —
trols are a comprehensive unit-management system. The control system is easy to access, configure, diagnose and troubleshoot.
The controls are 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, for multiple-stage gas heating, and hydronic heat in both Occupied and Unoccupied
schedule modes. This control also manages:
• VAV duct pressure (through optional VFD or inlet guide
vanes), with reset
• Building pressure through four different power exhaust
systems
• Return fan applications using fan tracking
• Condenser fan cycling for low ambient head pressure
control
• Dehumidification (with reheat) and humidifier sequences
• Space ventilation control, in Occupied and Unoccupied
periods, using CO
tilation defined by damper position or ventilation airflow
measurement
• 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
System diagnostics are enhanced by the use of multiple
external sensors for air temperatures, air pressures and refrigerant pressures. Unit-mounted actuators provide digital feedback
data to the unit control.
The ComfortLink™ controller is fully communicating and
cable-ready for connection to the Carrier Comfort Network
(CCN) building management system. The control provides
high-speed communications for remote monitoring via the
Internet. Multiple 48/50Z Series units can be linked together
(and to other ComfortLink controller equipped units) using a
3-wire communication bus.
The ComfortLink control system is easy to access through
the use of a unit-mounted display module. There is no need to
bring a separate computer to this unit for start-up. Access to
control menus is simplified by the ability to quickly select from
11 menus. A scrolling readout provides detailed explanations
of control information. Only four, large, easy-to-use buttons are
required to maneuver through the entire controls menu. The
display readout is designed to be visible even in bright sunlight.
For added service flexibility, an accessory hand-held
Navigator™ module is also available. This portable device has
an extended communication cable that can be plugged into the
unit’s communication network either at the main control box or
at the 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 keypad 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 and is standard on all units. The scrolling marquee
display is a 4-key, 4-character, 16-segment LED (light-emitting
diode) display module. The display also contains an Alarm Status LED. See Fig. 1. The display is easy to operate using

Through the scrolling marquee, the user can access all of the
inputs and outputs to check on their values and status, configure operating parameters plus evaluate the current decision status for operating modes. Because the 48/50Z Series units are
equipped with suction pressure and discharge pressure 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 marquee,
the user can access a built-in test routine that can be used at
start-up commissioning and to diagnose operational problems
®
with the unit.
Accessory Navigator™ Display — The accessory
hand-held Navigator display can be used with the 48/50Z
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-11 jack in the main control box
on the COMM board. The Navigator display can also be
plugged into the RJ-11 jack located on the unit corner post
located at the economizer end of the unit.

Operation — All units are shipped from the factory with
the scrolling marquee display, which is located in the main control box. See Fig. 1. In addition, the ComfortLink™ controls
also supports the use of the handheld Navigator™ display.
Both displays provide the user with an interface to the
ComfortLink 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 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
and arrow keys to scroll through the top-level categories. 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
ENTER
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
ESCAPE
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 indicating the full meaning of each display point. Pressing the
ESCAPE
(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 (FA N. 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
ESCAPE ENTER
key until a blank display is shown. Then use the
key to enter the mode. Depending on the mode, there

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 devices operating on the Carrier communicating network.
Additionally, the System Pilot interface can serve as a wallmounted temperature sensor for space temperature measurement. 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 reference, 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 displayed in the GENERIC points table. Each one of these placeholders 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 entering point names, download the table to the rooftop unit control.

IMPORTANT: The computer system software
(ComfortVIEW™, 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 tables from a control. Thereafter, the software is only concerned with run time
data like value and hardware/force status. 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
table), that a complete new upload be 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.
START-UP
IMPORTANT: Do not attempt to start unit, even
momentarily, until all items on the Start-Up Checklist
(in installation instructions) and the following steps
have been completed.
Unit Preparation —
accordance with the installation instructions and applicable
codes.
Check that unit has been installed in
Unit Setup — Make sure that the economizer hood has
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 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 compressors are running.
IMPORTANT: Unit power must be on for 24 hours
prior to start-up of compressors. Otherwise damage to
compressors may result.
Evaporator Fan — Fan belt and fixed pulleys are factory-
installed. See Tables 3-25 for fan performance. Remove tape
from fan pulley, and be sure that fans rotate in the proper
direction. See Tables 26-28 for motor limitations. See Table 29
for air quantity limits. Static pressure drop is shown in
Tables 30A-30C.
FIELD-SUPPLIED FAN DRIVES — Supply fan and power
exhaust fan drives are fixed-pitch, non-adjustable selections, for
maximum reliability and long belt life. If the factory drive sets
must be changed to obtain other fan speeds, consult the nearest
Browning Manufacturing Co. sales office with the required new
wheel speed and the data from Physical Data and Supply Fan
Drive Data tables (center distances, motor and fan shaft diameters, motor horsepower) in Installation Instructions for a modified drive set selection. For minor speed changes, the fan sheave
size should be changed. (Do not reduce the size of the motor
sheave; this will result in reduced belt horsepower ratings and
reduced belt life.) See page 128 for belt installation procedure.
Controls — Use the following steps for the controls:
1. Set any control configurations that are required (fieldinstalled 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, Navigator display, ComfortVIEW™
software or Service Tool to change the configuration
values.
3. If the internal time schedules are going to be used, configure the Occupancy schedule.
4. Verify that the control time periods programmed meet
current requirements.
5. Start unit using Service Test mode to verify operation of
all major components.
6. If the unit is a VAV unit make sure to configure the static
pressure set point. To check out the VFD, use the VFD instructions shipped with the unit.
Gas Heat — Verify gas 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 fieldsupplied manual shutoff valves.
3. Connect pressure gages to manifold pressure tap on unit
gas valve.
4. Supply gas pressure must not exceed 13.5 in. wg. Check
pressure at field-supplied shut-off valve.
5. Turn on manual gas stop and initiate a heating demand.
Jumper R to W1 in the control box to initiate heat.
6. Use the Service Test procedure to verify heat operation.
7. After the unit has run for several minutes, verify that
incoming pressure is 5.0 in. 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.
