nents. Only trained and qualified service personnel should

install, repair, or service air-conditioning equipment. Untrained

personnel can perform the basic maintenance functions of

replacing filters. Trained service personnel should perform all

other operations.

When working on air-conditioning equipment, observe pre-

cautions in the literature, tags and labels attached to the unit,

and other safety precautions that may apply. Follow all safety

codes. Wear safety glasses and work gloves. Use quenching

cloth for unbrazing operations. Have fire extinguishers avail-

able for all brazing operations.

WARNING

Before performing service or maintenance operation on

unit turn off and lock off main power switch to unit.

Electrical shock can cause personal injury and death.

Shut off all power to this equipment during installation

and service. The unit may have an internal non-fused

disconnect or a field-installed disconnect.

CAUTION

This unit uses a microprocessor-based electronic control

system. Do not use jumpers or other tools to short out com-

ponents or to bypass or otherwise depart from recom-

mended procedures. Any short-to-ground of the control

board or accompanying wiring may destroy the electronic

modules or electrical components.

WARNING

1. Improper installation, adjustment, alteration, service,

or maintenance can cause property damage, personal

injury, or loss of life. Refer to the User’s Information

Manual provided with this unit for more details.

2. Do not store or use gasoline or other flammable

vapors and liquids in the vicinity of this or any other

appliance.

What to do if you smell gas:

1. DO NOT try to light any appliance.

2. DO NOT touch any electrical switch, or use any

phone in your building.

3. IMMEDIATELY call your gas supplier from a neigh-

bor’s phone. Follow the gas supplier’s instructions.

department.

GENERAL

This book contains Start-Up, Controls, Operation, Trouble-

shooting and Service information for the 48/50Z Series

rooftop units. See Table 1. These units are equipped with

ComfortLink™ controls version 4.X or higher. Use this guide

in conjunction with the separate installation instructions pack-

aged with the unit. Refer to the Wiring Diagrams literature for

more detailed wiring information.

The 48/50Z Series units provide ventilation, cooling, and

heating (when equipped) in variable air volume (VAV) and

constant volume (CV) applications.

Table 1 — Z Series Product Line

LEGEND

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). Informa-

tion on system operation and status are sent to the MBB pro-

cessor by various sensors and optional board that are located at

the unit and in the conditioned space. Access to the unit con-

trols for configuration, set point selection, schedule creation,

and service can be done through a unit-mounted scrolling mar-

quee. 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 pres-

sure 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 transduc-

ers 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 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 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

BASIC CONTROL USAGE

ComfortLink™ Controls — The ComfortLink con-

trols are a comprehensive unit-management system. The con-

trol system is easy to access, configure, diagnose and trouble-

shoot.

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 heat-

ing, 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 CO2 sensors or external signals, with ven-

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 refriger-

ant 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 Sta-

tus LED. See Fig. 1. The display is easy to operate using

4 buttons and a group of 11 LEDs that indicate the following

menu structures:

• 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-

tus for operating modes. Because the 48/50Z Series units are

equipped with suction pressure and discharge pressure trans-

ducers, 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.

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.

Fig. 2 — Accessory Navigator Display

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 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 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.

START-UP

Unit Preparation — Check that unit has been installed in

accordance with the installation instructions and applicable

codes.

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 compres-

sors are running.

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 diame-

ters, motor horsepower) in Installation Instructions for a modi-

fied 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 (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, Navigator display, ComfortVIEW™

software or Service Tool to change the configuration

values.

3. If the internal time schedules are going to be used, config-

ure 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 in-

structions 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 field-

supplied 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.

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, 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 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.

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.

IMPORTANT: Unit power must be on for 24 hours

prior to start-up of compressors. Otherwise damage to

compressors may result.

*If calculating static pressure for a 48 Series unit, be sure to add gas

heat pressure drop from Table 30C.

NOTES:

1. Fan performance is based on wet coils and clean 2-in. filters.

2. For return fan (48Z6,Z8 and 50Z6,Z7,Z8,Z9) and high-capacity

power exhaust (48ZT,ZW and 50ZT,ZW,ZX,ZZ) units, add com-

ponent pressure drop for economizer. Do not add component

pressure drop for power exhaust.

3. See Table 30C before using Fan Performance tables.

4. Conversion — Bhp to kW:

See Tables 26-28 for motor efficiency.
