The A Series units provide ventilation, cooling, and heating (when equipped) in variable air volume (VAV), variable volume and temperature (VVT®), and constant volume (CV) applications. The A Series units contain the factory-installed Com- fortLink™ 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 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 ComfortVIEW™ software, the accessory Navigator™ handheld display, or the System Pilot™ interface.

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 are equipped with a standard VFD (variable frequency drive) for supply fan speed control and supply duct pressure control. The ComfortLink controls adjust the speed of the VFD based on a static pressure sensor input. In addition, the ComfortLink controls can raise or lower the building pressure using multiple power exhaust fans controlled from economizer damper position or from a building pressure sensor. The control safeties are continuously monitored to ensure safe operation under all conditions. Sensors include suction pressure transducers, discharge pressure transducers, and saturated condensing temperature sensors which allow for display of operational pressures and saturation temperatures.

(CCN) system using the

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 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 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. 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 represents 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 time will display an expanded text description of the fourcharacter 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 —

system is a comprehensive unit-management system. The control system is easy to access, configure, diagnose and troubleshoot.

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 CO

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

external sensors for air temperatures, air pressures, refrigerant temperatures, and refrigerant pressures. Unit-mounted actuators provide digital feedback data to the unit control.

The ComfortLink control system is fully communicating

and cable-ready for connection to the Carrier Comfort Net-

work

(CCN) building management system. The control provides high-speed communications for remote monitoring via the Internet. Multiple units can be linked together (and to other ComfortLink control 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.

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 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-character LED (light-emitting diode) display module. The display also contains an Alarm Status 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, 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, configure operating parameters plus evaluate the current decision status 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

marquee, the user can access a built-in test routine that can be used at start-up commissioning to diagnose operational problems with the unit.

Accessory Navigator™ 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 main control box. See Fig. 1. In addition, the ComfortLink™ controls also support the use of the handheld Navigator display.

Both displays provide the user with an interface to the ComfortLink 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 displays 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 indicating 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 (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 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 Carrier 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 devices 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 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 — 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 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 displayed 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 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, 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 GENERICS 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 CCN interface will have a different

table database than the unit control.

Programming Operating Schedules — The

ComfortLink™ controls will accommodate up to eight different schedules (Periods 1 through 8), and each schedule is assigned to the desired days of the week. Each schedule includes an occupied on and off time. As an example, to set an occupied schedule for 8 AM to 5 PM for Monday through Friday, the user would set days Monday through Friday to ON for Period 1. Then the user would configure the Period 1 Occupied From point to 08:00 and the Period 1 Occupied To point to 17:00. To create a different weekend schedule, the user would use Period 2 and set days Saturday and Sunday to ON with the desired Occupied On and Off times. To create a schedule, perform the following procedure:

NOTE: By default, the time schedule periods are programmed for 24 hours of occupied operation.

1. Scroll to the Configuration mode, and select CCN CONFIGURATION (CCN). Scroll down to the Schedule Number (Configuration password protection has been enabled, the user will be prompted to enter the password before any new data is accepted. SCH.N has a range of 0 to 99. The default value is 1. A value of 0 is always occupied, and the unit will control to its occupied set points. A value of 1 means the unit will follow a local schedule, and a value of 65 to 99 means it will follow a CCN schedule. Schedules 2 to 64 are not used as the control only supports one internal/local schedule. If one of the 2 to 64 schedules is configured, then the control will force the number back to 1. Make sure the value is set to 1 to use a local schedule.

2. Enter the Time Clock mode. Scroll down to the LOCAL TIME SCHEDULE (SCH.L) sub-mode, and press ENTER. Period 1 (PER.1) will be displayed. Press ENTER to configure Period 1.

3. Configure the beginning of the occupied time period for Period 1 (OCC). Scroll down to OCC and press ENTER to go into Edit mode. The first two digits of the 00.00 will start flashing. Use the UP or DOWN key to display the



correct value for hours, in 24-hour (military) time. Press ENTER and hour value is saved and the minutes digits will start flashing. Use the same procedure to display and save the desired minutes value. Press ESCAPE.

4. Configure the unoccupied time for period 1 (UNC). Scroll down to UNC and press ENTER to go into Edit mode. The first two digits of the 00.00 will start flashing. Use the UP or DOWN key to display the correct value for hours, in 24-hour (military) time. Press ENTER and hour value is saved and the minutes digits will start flashing. Use the same procedure to display and save the desired minutes value. Press ESCAPE.

5. Scroll to DAYS and press ENTER. Scroll down to the MON point. This point indicates if schedule 1 applies to Monday. Use the ENTER command to go into Edit mode, and use the UP or DOWN key to change the display to YES or NO. Scroll down through the rest of the days and apply schedule 1 where desired. The schedule can also be applied to a holiday. Press ESCAPE.

6. The first schedule is now complete. If a second schedule is needed, such as for weekends or holidays, scroll down and repeat the entire procedure for period 2 (PER.2). If additional schedules are needed, repeat the process for as many as are needed. Eight schedules are provided.

SERVICE TEST

General —

ture, which is intended to allow a service person to force the unit into different modes of operation to test them. To use this feature, enter the Service Test category on the local display and place the unit into the test mode by changing Service

Te st



TEST from OFF to ON. The display will prompt for the

password before allowing any change. The default password is

1111. Once the unit enters the Service Test mode, the unit will shut down all current modes.

TEST — The TEST command turns the unit off (hard stop) and allows the unit to be put in a manual control mode.

STOP — The STOP command completely disables the unit (all outputs turn off immediately). Once in this mode, nothing can override the unit to turn it on. The controller will ignore all inputs and commands.

S.STP — Setting Soft Stop to YES turns the unit off in an orderly way, honoring any time guards currently in effect.

FAN. F — By turning the FAN FORCE on, the supply fan is turned on and will operate as it normally would, controlling duct static pressure on VAV applications or just energizing the fan on CV applications. To remove the force, press ENTER and then press the UP and DOWN arrows simultaneously.

F. 4 . C H — The 4-Inch Filter Change Mode variable is used to service the unit when 4-in. filters are used. When the filters need to be changed, set Service Test will be placed in Service Test mode and the economizer will move to the 40% open position to facilitate removal of the 4-in. filters. After the filters have been changed, set Service

Te st



F. 4 . C H = NO to return the unit to normal operation.

The remaining categories: INDP, FANS, COOL, and HEAT are sub-modes with separate items and functions. See Table 41.

The units are equipped with a Service Test fea-



F. 4 . C H = YES. The unit

Service Test Mode Logic — Operation in the Service

Test mode is sub-mode specific except for the Independent submode. Leaving the sub-mode while a test is being performed and attempting to start a different test in the new sub-mode will cause the previous test to terminate. When this happens, the new request will be delayed for 5 seconds. For example, if compressors were turned on under the COOL sub-mode, any attempt to turn on heating stages within the HEAT sub-mode would immediately turn off the compressors and, 5 seconds later, the controller would honor the requested heat stages.

However, it is important to note that the user can leave a Service Test mode to view any of the local display modes and the control will remain in the Service Test mode.

Independent Outputs — The INDP sub-mode items

can be turned on and off regardless of the other category states. For example, the alarm relay can be forced on in the INDP sub-mode and will remain on if compressor relays are requested in the COOL sub-mode.

Fans in Service Test Mode — Upon entering the

FA NS sub-mode, the user will be able to turn the supply fan on and off, set the supply fan VFD speed, and turn the condenser fans on and off.

Cooling in Service Test Mode — The COOL sub-

mode offers different cooling service tests.

The user has manual relay control of individual compressors. If the user energizes mechanical cooling, the supply fan and the outdoor fans will be started automatically. During mechanical cooling, the unit will protect itself. Compressor diagnostics are active, monitoring for high discharge pressure, low suction pressure, etc. The user can also turn the hot gas bypass valve on and off.

NOTE: It is crucial that proper compressor rotation be verified during the service test. Each compressor must be tested

individually. After starting each compressor, the control will check the suction pressure after 5 seconds of run time. If the control does not see a sufficient decrease in suction pressure after 5 seconds, mechanical cooling will be shut down, and an alarm will be generated (A140). This alarm requires a manual reset. If this alarm occurs, do not attempt a restart of the compressor and do not attempt to start any other compressors until the wiring to the unit has been corrected.

Heating in Service Test Mode — If unit has a ther-

mostat connected (C.TYP = 3 or 4), install the RED jumper wires between TB4, terminals R (1), W2 (3) and W1 (4). Terminal block TB4 is located in the unit control box. Remember to disconnect these jumpers when Test Mode is completed. The Heat Test Mode sub-mode will offer automatic fan start-up if the unit is not a gas heat unit. On gas heat units, the IGC feedback from the gas control units will bring the fan on as required.

Within this sub-mode, the user has control of heat relays 1

to 6. The user can also turn on the requested heat stage. NOTE: When service test has been completed, if unit has a

thermostat connected (C.TYP = 3 or 4), remove the RED jumper wires at TB4, terminals R (1), W2 (3) and W1 (4). Terminal block TB4 is located in the unit control box. Store these jumpers in the unit control box for future use.
