SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
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. All other operations should be performed by
trained service personnel. When working on air-conditioning
equipment, observe precautions 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 available for all brazing operations.
GENERAL
This publication contains Start-Up, Controls, Operation,
and Troubleshooting information for the 48/50HG rooftop
units. See Table 1. These units are equipped with ComfortLink
controls.
Table 1 — Unit Sizes (48/50HG)
MAJOR SYSTEM COMPONENTS
General — The 48/50HG single package rooftop units with
electric cooling and with gas heating (48HG units) or electric
cooling and electric heating (50HG Units) contain the
ComfortLink electronic control system that monitors all opera-
tions of the rooftop. The control system is composed of several
components as listed in sections below. See Fig. 1-3 for the
control and power schematics. Figure 4 shows the layout of the
control box, unit, and thermistor and transducer locations.
Main Base Board (MBB) — See Fig. 5. The MBB is
the center of the ComfortLink control system. It contains the
major portion of the operating software and controls the opera-
tion of the unit. The MBB continuously monitors input/output
channel information received from its inputs and from the
Economizer Control Board (ECB). The MBB receives inputs

from thermistors T1 through T5 and transducers T6 through
T8. See Table 2. The MBB also receives the Current Sensor
inputs for compressors A1, B1 and C1 and other discrete or
digital inputs. See Table 3. The MBB reads space temperature
(SPT) from either a T55, T56 or T58 device and space temper-
ature offset (SPTO) from a T56 device. See Table 4 and Field-
Installed Accessories section below. The MBB controls 11 re-
lays. See Table 5.
Economizer Control Board (ECB) — The ECB con-
trols the economizer actuator. See Fig. 6. Relay 6 on the ECB
supplies 24 VAC to the actuator. The control signal from the
ECB uses the Belimo communication protocol. The ECB has
inputs for Indoor Air Quality (IAQ), Outdoor Air Quality
(OAQ), and enthalpy. See Table 4. It also controls two power
exhaust motors (PE1 and PE2). See Table 5.
By communicating with the ECB, the economizer actuator
is able to provide the damper position and diagnostic informa-
tion to the ComfortLink controller. The damper position is dis-
played as EC.AP under Outputs/Econ on the Scrolling Mar-
quee. Diagnostic information is displayed via Alert T414.
More information about these alarms is contained in the
Alarms and Alerts section.
Scrolling Marquee Display — This device is the key-
pad interface used to access rooftop information, read sensor
values, and test the unit. See Fig. 7. The marquee display is a
4-key, 4-character, 16-segment LED (light-emitting diode)
display. Eleven mode LEDs are located on the display as well
as an Alarm Status LED. See Marquee Display Usage section
on page 11 for further details.
Board Addresses — The Main Base Board (MBB) has
a 3-position instance jumper that is set at the factory to “1.”
Do not change this setting. The ECB has a 4-position DIP
switch. Each DIP switch is set to “0” at the factory. Do not
change this setting.
Control Module Communication
RED LED — Proper operation of the control boards can be
visually checked by looking at the red status LEDs. When
operating correctly, the red status LEDs should blink in unison
at a rate of once every 2 seconds. If the red LEDs are not blink-
ing in unison, verify that correct power is being supplied to all
modules. Also, be sure that the Main Base Board is supplied
with the current software. If necessary, reload current software.
If the problem still persists, replace the MBB. A board LED
that is lit continuously or blinking at a rate of once per second
or faster indicates that the board should be replaced.
GREEN LED — The MBB has one green LED. The Local
Equipment Network (LEN) LED should always be blinking
whenever power is on. All other boards have a LEN LED that
will blink whenever power is on. If LEN LED is not blinking,
check LEN connections for potential communication errors
(J3 and J4 connectors). Communication between modules is
accomplished by a 3-wire sensor bus. These 3 wires run in
parallel from module to module. The J4 connector on the MBB
provides both power and communication directly to the
marquee display.
YELLOW LED — The MBB has one yellow LED. The
Carrier Comfort Network (CCN) LED will blink during times
of network communication.
Carrier Comfort Network Interface — The 48/50HG
units can be connected to the CCN if desired. The communica-
tion bus wiring is a shielded, 3-conductor cable with drain wire
and is field supplied and installed. See Table 6 for wiring infor-
mation. The system elements are connected to the communica-
tion bus in a daisy chain arrangement. The positive pin of each
system element communication connector must be wired to the
positive pins of the system elements on either side of it. This is
also required for the negative and signal ground pins of each
system element. Wiring connections for CCN should be made
at TB2. See Fig. 1 and 2. Consult the CCN Contractor's Manu-
al for further information.
NOTE: Conductors and drain wire must be 20-AWG (Ameri-
can Wire Gage) minimum stranded, tinned copper. Individual
conductors must be insulated with PVC, PVC/nylon, vinyl,
Teflon, or polyethylene. An aluminum/polyester 100% foil
shield and an outer jacket of PVC, PVC/nylon, chrome vinyl,
or Teflon with a minimum operating temperature range of
–20 C to 60 C is required. See Table 6.
It is important when connecting to a CCN communication
bus that a color-coding scheme be used for the entire network
to simplify the installation. It is recommended that red be used
for the signal positive, black for the signal negative and white
for the signal ground. Use a similar scheme for cables contain-
ing different colored wires.
At each system element, the shields of its communication
bus cables must be tied together. If the communication bus is
entirely within one building, the resulting continuous shield
must be connected to a ground at one point only. If the commu-
nication bus cable exits from one building and enters another,
the shields must be connected to grounds at the lightning
suppressor in each building where the cable enters or exits the
building (one point per building only). To connect the unit to
the network:
1. Turn off power to the control box.
2. Cut the CCN wire and strip the ends of the red (+), white
(ground), and black (–) conductors. (Substitute appropri-
ate colors for different colored cables.)
3. Connect the red wire to (+) terminal on TB2 of the plug,
the white wire to COM terminal, and the black wire to the
(–) terminal.
4. The RJ14 CCN connector on TB2 can also be used, but is
only intended for temporary connection (for example, a
laptop computer running Service Tool).
5. Restore power to unit.
Field-Installed Accessories
SPACE TEMPERATURE SENSOR (T55) — The T55 Space
Temperature Sensor (Part No. CEC0121448-01) is a field-
installed accessory. The sensor is installed on a building interi-
or wall to measure room air temperature. The T55 sensor also
includes an override button on the front cover to permit occu-
pants to override the Unoccupied Schedule (if programmed).
The jumper wire in the installer’s packet must be connected
between R and W1 when using a T55 device. See Fig. 8-10.
SPACE TEMPERATURE SENSOR (T56) — The T56 Space
Temperature Sensor (Part No. CEC0121503-01) is a field-
installed accessory. This sensor includes a sliding scale on the
front cover that permits an occupant to adjust the space temper-
ature set point remotely. The jumper wire in the installer’s
packet must be connected between R and W1 when using a
T56 device. See Fig. 8, 9, and 11.
IMPORTANT: A shorted CCN bus cable will prevent
some routines from running and may prevent the unit
from starting. If abnormal conditions occur, unplug the
connector. If conditions return to normal, check the
CCN connector and cable. Run new cable if necessary.
A short in one section of the bus can cause problems
with all system elements on the bus.

key again so that the item value flashes. Use the
arrow keys to change the value or 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. See Tables 7-21 for further details.
Clearing Unit Alarms —The unit alarms can be cleared
through the ComfortLink display. To check the current alarms,
enter into the Alarms menu. The first submenu is the CURR
submenu. The CURR function displays the list of current
alarms (maximum of 25). The second submenu item is the
R.CUR (Reset Current Alarms) function. Press to re-
set the current alarms. The next submenu item, HIST, displays
the list of cleared alarms (maximum of 20). The HIST function
can be cleared with the R.HIS function. See Tables 21 and 22.
ECONOMIZER CALIBRATION — Because of a mechani-
cal problem with the economizer, the actuator might acquire a
new degree of rotation which is less than 90 degrees. If this
occurs, a “T414 Economizer Damper Actuator Out of Calibra-
tion” alert will be generated. The economizer calibration proce-
dure (E.CAL under the INDP submenu) will reconfigure the
actuator to the new fully closed and fully open positions. To
implement the calibration procedure, change E.CAL from OFF
to ON. E.CAL will remain ON as long as the calibration proce-
dure is being implemented (as long as 5 minutes). During the
calibration procedure the actuator will close fully and then
open fully. After the calibration is complete, the degree of rota-
tion should be greater than 90 degrees, causing the T414 alarm
to clear. If the T414 alert does not clear, check the economizer
damper for other mechanical problems.
IMPORTANT: A T58 sensor can only be used with unit
running Version 2.0 or higher of the unit software. If a
T58 sensor is installed but will not function with the 48/
50HG unit, check the unit software version with the
ComfortLink controls. The new version of the software
may need to be loaded into the unit controls.

Service Test —The Service Test function can be used to
verify proper operation of compressors, indoor, outdoor and
power exhaust fans, heaters, economizer and alarm relay. The
Service Test function can also be used to calibrate the econo-
mizer. Refer to Table 9. Use the display keys to enter the mode
and display TEST. Press twice so that OFF flashes.
Enter the password if required (1111 default). Use either arrow
key to change the TEST value to the ON position and press
. By selecting ON, Service Test mode is now enabled.
Press and the button to enter the INDP, FANS,
COOL or HEAT submodes.
Of these four submodes, only INDP is independent, and
therefore only its items can be changed at any time without
affecting the performance of other items (FANS, COOL or
HEAT submodes). For example, if A1 was selected from the
COOL submode, compressor A1 would operate with the
indoor fan and necessary outdoor fans. If ECON (part of
INDP) was changed, the performance of the COOL outputs
would not be affected. However, if the user selected IDF from
FANS, all of the outputs currently operating because of A1,
including IDF, would be turned off and then IDF would be
turned on again after a small delay. The ECON setting, as a
member of INDP, would not be affected.
This system of dependent and independent submodes was
developed to ensure that the indoor and outdoor fans were
adequately controlled at all times. It was also implemented to
make sure that certain outputs, which could cause the MCA
(Minimum Current Amps) and the MOCP (Maximum Over-
current Protection) of the unit to be exceeded, do not operate at
the same time.
The INDP submode can used to test the system outputs that
are independent and can operate in all modes: fan only, cooling
and heating. These outputs are ECON, E.PWR, PE.1, PE.2 and
ALM.
When an economizer output (ECON) other than zero is
selected, the economizer power relay E.PWR will automatical-
ly be turned ON and the economizer is moved to the selected
position. Afterwards, the user can turn off the power to the
economizer by setting E.PWR to OFF. However, this will not
turn off ECON. If the user reselects ECON, the economizer
power relay will once again be turned ON.
