FEATURES/BENEFITS
Carrier’s Centurion 48PG commercial packaged rooftop unit is
Carrier’s most efficient, easiest to service, and most reliable rooftop
unit utilizing Puron refrigerant.
Premium Performance
The Centurion 48PG Series provides ARI (Air Conditioning and
Refrigeration Institute) certified cooling SEERs (Seasonal Energy
Efficiency Ratios) up to 14.8, EERs (Energy Efficiency Ratio) up
to 12.5 and IPLVs (Integrated Part--Load Values) up to 13.3. Gas
heating efficiencies are as high as 82%.
The 48PG unit well exceeds ASHRAE (American Society of
Heating, Refrigeration and Air Conditioning Engineers) 90.1 and
ENERGY STARr
levels. These efficiency ratings ensure low
operating costs, qualify for attractive utility rebates in many areas
and earn credits for Leadership in Energy and Environmental
Design (LEEDt) issued by Green Building Council.
These units offer ultra--high energy efficiency and environmental
benefits by utilizing Carrier’s Puronr (R--410A) refrigerant that
eliminates all concerns of mandated refrigerant phase out of R--22
(HCFC) in 2010. Each unit has been specifically designed for use
with Puron refrigerant to provide years of optimum efficiency.
The 48PG rooftop units accommodate easy installation.
Field--convertible units easily switch from vertical to horizontal
configuration. Units come factory standard with vertical discharge
and return duct configuration but can be easily converted in the
field for horizontal airflow. If needed, a factory option can be
ordered on larger sizes to specifically meet your exact
configuration, further saving installation costs.
The entire Centurion 48PG Series from 2 to 25 ton only uses 5
roof curb sizes. The contractor can order and install the roof curb
early in the construction stage, before decisions on size
requirements are made.
Unit controls provide optimum flexibility to meet any application
or customer requests. A choice of either base electro--mechanical
controls or the popular integrated intelligent ComfortLinkt
controls can be ordered from the factory.
Large component areas facilitate easy installation for electrical, gas
or any other field accessory that may be required.
All units feature rigid base rails with rigging holes for easier
maneuvering, rigging, and lifting to and on the job site. Durable
packaging protects all units during shipment and storage.
A full range of time saving factory--installed options are available
such as power exhaust, hail guards, breakers, smoke detectors, and
air management devices. All factory options are preengineered and
certified.
Large and accessible wiring terminal boards, located in the base
unit control box, facilitate connections to room thermostat or
sensor, outdoor thermostat(s), and economizer. Hinged service
panels are provided, permitting easy access.
Thru--the--curb power and control wiring connections route
through both the curb and unit, minimizing roof penetrations.
Connections are located in an enclosed area away from harsh
ambient conditions, eliminating water entry. Both power and
control connections are made on the same side of the unit to
simplify installation. In addition, color--coded and labeled wires
permit easy tracing and diagnostics.
The Carrier Centurion units with ComfortLink controls will
operate in the cooling mode down to 0_F ambient temperature,
eliminating the need for expensive aftermarket low ambient
controllers while providing comfort in the harshest environments.
Easy Maintenance and Service
Maintaining and servicing a rooftop unit has never been easier
thanks to the new Centurion design. Integrated hinged access
panels for the filter, indoor--fan motor/blower assembly,
compressors, control box, and gas heat areas provide quick access
to major components.
Each hinged panel has multiple heavy--duty quarter--turn
latches and is permanently mounted to the unit, thereby
eliminating the concern of a dropped or wind--blown panel
puncturing delicate roof materials. Door tie downs are also
provided to ensure panels remain stationary, eliminating any panel
blowback conditions.
Indoor fan system slides out for easy access. Blower wheels,
motors, belts, and bearings can be easily serviced and maintained.
Evaporator and condenser coils are of a single slab/single pass
design that facilitates optimum cleaning without unit disassembly
or coils separation as with hybrid type coil designs. Each coil has a
dedicated access door to ensure ease of cleaning.

provide temperature, pressure readings and all diagnostics
electronically on the unit by utilizing a large visual display on the
Scrolling Marquee. All messages are largely displayed in full text
so no decoding is required. All sensor information can be accessed
at the Scrolling Marquee, so no gages are needed. If remote
capabilities are necessary, ComfortLink provides network
capabilities as well.
Optional Humidi--MiZert Adaptive
Dehumidification System
Carrier’s Humidi--MiZer adaptive dehumidification system is an
all--inclusive factory--installed option that can be ordered with any
Centurion 48PG03--28 rooftop unit.
This system expands the envelope of operation of Carrier’s
Centurion rooftop products to provide unprecedented flexibility to
meet year--round comfort conditions.
The Humidi--MiZer adaptive dehumidification system has the
industry’s only dual dehumidification mode setting. The
Humidi--MiZer system includes two new modes of operation.
The Centurion 48PG03--28 rooftop coupled with the
Humidi--MiZer system is capable of operating in normal design
cooling mode, subcooling mode, and hot gas reheat mode. Normal
design cooling mode is when the unit will operate under its normal
sequence of operation by cycling compressors to maintain comfort
conditions.
Subcooling mode will operate to satisfy part load type conditions
when the space requires combined sensible and a higher proportion
of latent load control. Hot Gas Reheat mode will operate when
outdoor temperatures diminish and the need for latent capacity is
required for sole humidity control. Hot Gas Reheat mode will
provide neutral air for maximum dehumidification operation.
Optional fan and filter indicator switches will alert necessary
personnel when filters require changing or the system fan is not
operating properly.
Dedicated hinged filter door and with an Easy Glidet slide out
filter tracks make air filter replacement easy. This eliminates the
need to reach within the unit. All filters are a standard off--the--shelf
size for easy availability and lower replacement costs.
Compressors are located in a dedicated insulated compartment that
allows troubleshooting without creating air bypass that causes
misreadings and diagnostics.
Optional EnergyXt System
EnergyX is a factory integrated, single piece, fully tested and
certified energy recovery system specifically designed for the PG
series rooftop product family (vertical return duct only).
The EnergyX system recycles exhausted air and provides latent
and sensible energy exchange to intake air prior to entering either
the unit DX coil or heating section. This preconditioning of air
allows even higher operating efficiencies and increased comfort
control. Operating cost savings of up to 4 tons per 1,000 cfm in
cooling and 80,000 Btu/hour per 1,000 cfm in heating can be
achieved by the EnergyX system. This also would allow for the
base unit capacity requirements reduction and installation cost
savings, while providing lower life--cycle energy consumption
during operation.
The Combined Efficiency (CEF) by ARI Guideline V can be
higher than 19.0. EnergyX Energy Recovery Whell also is rated in
accordance with ARI 1060 and has UL/CUL certification.
EnergyX system comes with the following standard features:
S Double wall fully gasketed hinged access panels with
quarter--turn handles.
S Direct or belt drive exhaust and intake blower motors with
centrifugal fans.
S Exhaust and Intake 2--in filters (exhaust filters are optional).
S Single point electrical connection.
S Rotary heat exchanger wheel with desiccant silica gel coating.
S “Stop Jog” logic that prevents dirt and contaminants from
building on the wheel by rotating the wheel while the pressure
differential is sensed (provided with Economizer bypass models
only).
S Air flow test ports to properly balance the exhaust and intake air.
S Pre--assembled exhaust and intake hoods.
S Five year wheel warranty.
The following optional features are available with the
EnergyX system:
Frost protection
In extremely cold climates, this option monitors wheel pressure
drop and outside temperature. When outside air temperature is
20_F or lower and the pressure drop measurement confirms frost
build--up, the wheel activates and exhaust fan energizes to remove
accumulated frost.
Motor Status Switch
This factory option monitors the system pressure drop of all
EnergyX motors, which includes the intake, exhaust and rotating
energy wheel motors. If lack of pressure is detected, a signal is sent
to a field--supplied 24 volt indicator light advising that
maintenance is required (not available on 48PG03--07 units).
Filter Maintenance Switch
This factory--installed option monitors pressure drop through both
outside air and exhaust air filters. If excess pressure drop is
detected, a signal is sent to a field--supplied 24 volt indicator light
advising that maintenance is required (not available on 03--07
units). Exhaust filters are included.
Indoor Air Quality Begins With Carrier Rooftops
Two--in. disposable filters are factory furnished as standard in
every unit with the capability of accommodating 4--in. filters as
well as factory--installed MERV--8 pleated filters. The same track is
used so no special field kits are required on 48PG03--16 units. On
48PG20--28 units a factory--installed option is available.
Internally sloped condensate pans are self--draining to ensure
minimizing biological growth in rooftop units in accordance with
ASHRAE Standard 62.
All 48PG03--16 units use a high impact polycarbonate slide--out
condensate pan while the 48PG20--28 units use an epoxy
powder--coated steel condensate pan.
Unit uses foil--faced cleanable insulation that is securely fastened.
Selected panels are mechanically fastened for added support. All
edges are either sealed or encapsulated so no fibers enter the
airstream.
Optional tilt--out economizers (sizes 03--16) with single enthalpy
controls maximize building humidity control.
Built--in capability for DCV (demand control ventilation) is
standard and integrates with CO2 sensors, both as a
factory--installed option or a field--installed accessory.
Belt--driven evaporator fans provide quiet and efficient
operation. The belt--driven evaporator--fan with variable--pitch
pulleys allows adjustment to available static pressure to meet the
job requirements of even the most demanding applications.
Multiple motor and drive options are available to match system
airflow and static pressure requirements.

Optional ComfortLink Controls
Durable, Dependable Construction
Weather--resistant cabinets are constructed of galvanized steel
and all exterior panels are coated with a prepainted baked enamel
finish. The paint finish is a non--chalking type that provides years
of maximum aesthetic protection.
Fully--insulated cabinets include non--fibrous, foil--faced
cleanable insulation that is mechanically secured and encapsulated
in unit design.
Totally enclosed condenser--fan, gas heat vent motor, and
evaporator fan motor use permanently lubricated bearings to
provide additional unit dependability. The shaft--down design of
the condenser fan also ensures protection from the continued harsh
environments.

Quality and Reliability
To assure optimum life expectancy and performance, every rooftop
unit is factory run tested prior to shipping to the job site. Individual
components are also tested at many levels to assure than only the
best parts make it into the Carrier rooftop units. All units are
manufactured in a facility registered to ISO 9001:2000.
Reliable, fully hermetic scroll compressors with crankcase
heater(s) are mounted on a dedicated formed pad and are secured
for quiet operation.
A TXV (thermostatic expansion valve) for refrigerant metering
on each circuit allows efficient operation up to 125_F ambient
cooling temperature, with removable power head.
Each circuit contains a solid core liquid line filter drier specifically
designed for Puron refrigerant systems.
Units contain provisions to eliminate internal damage if a blower
motor belt breaks or comes off during operation. Specially located
stop bars or strategically located belt drive eliminates damages to
sensitive areas such as coils, piping and metering devices.
Standard warranty coverage provides one--year parts warranty,
5--year compressor warranty, and 10--year aluminized gas heat
exchanger warranty (15 years on stainless steel heat exchanger).
Integrated Economizers and Outdoor Air
Management
During a call for cooling, if the outdoor--air temperature is below
the control changeover set point, unit control modulates the
economizer outdoor--air damper open to achieve the set point. If
economizer cooling is not sufficient, additional compressor stages
are energized in addition to the economizer. If the outdoor--air
temperature is above the changeover set point, the first stage of
compression is activated and the economizer stays at minimum
position. Economizer operation is controlled by a thermistor that
senses outdoor--air temperature.
Gear driven, spring return, close on power loss economizers
with dry bulb or single enthalpy are available as a factory--installed
option as well as two--position motorized dampers, manual
dampers and power exhaust. All provide the flexibility to meet any
application needs or codes.
Ultra Low Sound
Outdoor sound levels of 72 dB are the lowest in the industry for
this type of equipment. Low sound levels allow for maximum
installation flexibility and greater indoor environmental comfort,
and reduce or eliminate the need for expensive sound barriers
required by many others.
Integrated Gas Heating Unit Controller (IGC)
Provides 2--stage Heating Capacity Control on All
Sizes.
All ignition components are contained in the compact IGC that is
easily accessible for servicing. The IGC control board, designed
and manufactured exclusively for Carrier rooftop units, provides
built--in diagnostic capability. An 4 LED (light--emitting diode)
simplifies troubleshooting by providing visual fault notification
and system status confirmation.
The IGC also contains an anti--cycle protection for gas heat
operation. After 4 continuous automatic cycles on the unit
high--temperature limit switch, the gas heat operation is disabled,
and an error code is issued. This feature greatly improves reliability
of the rooftop unit.
The IGC also contains burner control logic for accurate and
dependable gas ignition. This LED fault--notification system
reduces service person troubleshooting time and minimizes service
costs. The IGC can also maximize heating efficiency by controlling
evaporator fan on and off delays.
Efficient, Dependable Operation
Tubular, dimpled gas heat exchangers optimize heat transfer for
improved efficiency. The tubular design permits hot gases to make
multiple passes across the path of the supply air. The dimpled
design creates a turbulent gas flow to maximize heating efficiency.
The extra thick Alumagardt heat exchanger coating provides
corrosion resistance and ensures long life. An optional stainless
steel heat exchanger is also available.
The induced draft combustion system eliminates the unsightly
appearance of flue stacks and diminishes the effects of wind on
heating operations. The inducer fan draws hot combustion gas
through the heat exchanger at the optimum rate for the most
effective heat transfer. Induced draft heating systems are safer than
positive pressure, forced draft heating systems. With the induced
draft heating system, the heat exchanger operates under negative
pressure, preventing flue gas leakage into the indoor supply air.
During the Heating mode, the evaporator--fan relay automatically
starts the evaporator fan after the heat exchanger warms up to a
suitable temperature. The 30--second fan delay prevents cold air
from entering the supply duct system when the conditioned space
is calling for heat to maximize efficiency.
The direct--spark ignition system saves operating expense when
compared to pilot ignition systems. No crossover tube is required,
therefore no sooting or pilot fouling problems can occur.
Safety is built in
All 48PG units have a flame rectification sensor to quickly sense
the burner flame. Fast shutdown is a certainty since the sensor
reacts quickly to any flame outage or system failure. In the event of
a shutdown, an error code is issued at the IGC board.
Heating safety controls will shut down the unit if there is a
problem. If excessive temperatures develop, limit switches shut off
the gas valve. After 4 continuous short cycles of the high
temperature limit switch, the IGC board locks out the gas heat
cycle to prevent any further short cycles. This safety feature is
provided exclusively on Carrier rooftop units. The rollout switch
also de--energizes the gas valve in the event of a flame rollout.

The ComfortLink control is your link to a world of simple and easy
to use rooftop units that offer outstanding performance and value.
When used with a space temperature sensor, the ComfortLink
controls’ intelligence maintains control over the economizer and
condenser fans and optimizes the performance of the refrigeration
circuits as conditions change resulting in the following features:
S better control of temperature and humidity
S superior reliability
S automatic redundancy
S low ambient cooling operation to 0_F
S more accurate diagnostics, at unit or remote
The ComfortLink Scrolling Marquee is very easy to use. The
messages are displayed in easy to understand English, no decoding
is required. A scrolling readout provides detailed explanations of
control information. Only four, large, easy--to--use buttons are
required to maneuver through the entire menu. The readout is
designed to be visible even in the brightest sunlight. A handheld
Navigatort accessory or System Pilott device can be used for
added service flexibility.
The ComfortLink control provides unparalleled service diagnostic
information. Temperature and pressure can be read directly from
the display with no need for separate gages. Other data, such as
compressor cycles, unit run time hours, current alarms, can also be
accessed. A history of alarms is also available for viewing.
The service run test can be very helpful when troubleshooting. The
user can run test major components to determine the root cause of a
problem. The unit can be run--tested before an installation is
complete to ensure satisfactory start--up.
To ensure reliability, the ComfortLink control prevents reverse
compressor rotation.
No laptop computers are required for start--up. Time schedules are
built in and the Scrolling Marquee display provides easy access to
set points.
The ComfortLink control accepts input from a CO2 sensor and a
smoke detector. Both are available as factoryinstalled options or as
field--installed accessories.
ComfortLink controls are fully communicating and are
cable--ready for connection to the Carrier Comfort Networkr
(CCN) communication network. The control communicates at 38.4
kilobaud. This provides highspeed communications for remote
monitoring via the Internet. Multiple Centurion rooftop units can
be daisychained together using a 3--wire communication bus at the
rooftop level. The ComfortLink/CCN system is a peer--to--peer
system, rather than a polling system. This results in lower cost
installations.
The Centurion rooftop units have a terminal strip on board,
therefore, the Centurion units can operate with a standard
thermostat. Expensive interface devices are not required.
3Vt Control System
The Centurion rooftop unit is linkage compatible for use with the
3V zoning system. Carrier’s 3V control system provides optimized
equipment control through airside linkage. Linkage allows the
Centurion rooftop unit to adjust its supply air temperature set
points and occupancy schedules to run in the most efficient
manner. The 3V zoning system maintains precise temperature
control in the space by regulating the flow of conditioned air into
the space using Carrier’s VVTR Zone and Bypass Controllers.

Determine cooling and heating requirements at design
conditions.
Given:
Required Gross Cooling
Capacity (TC) . . . . . . . . . . . . . . . .57,000 Btuh
Gross Sensible Heat
Capacity (SHC) . . . . . . . . . . . . . . .37,000 Btuh
Required Heating Capacity . . . . . . . .90,000 Btuh
Condenser Entering Air
Temperature . . . . . . . . . . . . . . . . 95_F Summer
Indoor Air Temperature . . . . . .80_F edb, 67_F ewb
Evaporator Air Quantity. . . . . . . . . . . . 1,700 cfm
External Static Pressure . . . . . . . . . . . .0.60 in. wg
Electrical Characteristics (V--Ph--Hz) . . . . . 230--3--60
Vertical supply required.
Select unit based on required cooling capacity.
Enter Cooling Capacities table for 48PGE06 at condenser entering temperature of 95_F, evaporator air quantity
of 1,700 cfm, and indoor air temperature of 80/67_F.
The 48PGE06 unit will provide a total cooling capacity
of 60,300 Btuh and a SHC of 41,800 Btuh. For evaporator air temperatures other than 80_F, calculate SHC
correction using formula in notes under cooling capacity
tables.
Unit meets design conditions for TC and SHC
NOTE: Unit ratings are gross capacities and do not include the effect of indoor fan motor heat. To calculate net
capacities, see Step V.
Select heating capacity of unit to provide design condition
requirement.
In Heating Capacities and Efficiencies table, note that
48PGE06 (medium heat) unit will provide 91,500 Btuh
with an input of 113,000 Btuh.
IV.
Determine fan speed and power requirements at design
conditions.
S
Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
Tabulated fan performance includes unit casing, filters,
and wet evaporator coil.
S
Calculate pressure drop:
Design External Static Pressure
0.60
0.60 in.wg (ESP)
Enter Fan Performance tables for 48PGE06 (medium
heat units, vertical supply) at 1,700 cfm and 0.60 in. wg.
The rpm is 826 and the Bhp is 0.6. The factory--installed
1--1/2 hp motor and standard drive are sufficient for this
operation.
V.
Determine net cooling capacities.
S
Cooling capacities are gross capacities and do not include indoor (evaporator) fan motor (IFM) heat. To
determine input power to the motor, enter the Fan
Performance tables for 48PGE06 (medium heat units) at
1,700 cfm and 0.60 in. wg. Calculated input watts to the
motor are 613.
S
Determine Input Watts
Input Watts = (746 x Bhp)/(motor eff)
Input Watts = (746 x 0.60)/(0.73)
Input Watts = 613
S
Determine net cooling capacity and net sensible cooling
capacity using the following formulas:
IFM Heat = Input Watts x 3.412 Btuh/Watt
= 613 x 3.412
= 2091 Btuh
Net Capacity = Gross Capacity -- IFM Heat
= 60,300 -- 2091
= 58,208 Btuh
Net Sensible Cap. = Gross Sensible Cap. -- IFM Heat
= 41,800 -- 2091
= 39,709 Btuh
The calculations show that a 48PGE06 unit is the correct
selection for the given conditions.
VI. Select the unit that corresponds to power source available.
The electrical data table shows that the 230--3--60 unit is
available.

1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet--- bulb temperature corresponding to enthalpy of air leaving evaporator
coil (hlwb)
total capacity (Btuh)
4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil
hlwb = hewb –

that the full horsepower range of the motor can be utilized
to external static pressure before entering Fan Performance
with confidence. Using your fan motors up to the bhp rating
table.

motor failure. Unit warranty will not be affected.
2. Interpolation is permissible. Do not extrapolate.
5. Use of a field-supplied motor may affect wire size.
3. Fan performance is based on wet coils, clean filters, and

* Derating of the gas heating equipment to compensate for the effects of
altitude is always required. Orifice change is not required if the fuel heating
value (at sea level) is below the limits listed in the table above. Derating
conditions must be 4% per thousand ft above sea level. For example, at 400
ft, if the heating value of the gas exceeds 100 Btu/ft3, the unit will require a
16% derating. For elevations above 600 ft, the same formula applies. For
example, at 7000 ft, the unit will require a 28% derating of the maximum
heating value per the National Fuel Gas Code.

NOTES:
1. Extensive motor and electrical testing ensures that the motors can be utilized with confidence up to the maximum applied bhp, watts, and amps. Using the fan
motor up to the maximum ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.
2. Convert bhp to watts using the following formula:
bhp (746)
motor efficiency
3. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors. Motors regulated by EPACT include any gener
al purpose, T ---frame (three ---digit, 143 and larger), single ---speed, foot mounted, polyphase, squirrel cage induction motors of NEMA (National Electrical
Manufacturers Association) design A and B, manufactured for use in the United States. Ranging from 1 to 200 Hp, these continuous---duty motors operate on
230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does not have to be replaced by an EPACT ---compliant energy ---effi
cient motor. Variable ---speed motors are exempt from EPACT compliance requirements. Therefore, the indoor fan motors for Carrier 48PG03 ---16 units are
exempt from these requirements.

Example: Supply voltage is 230-3-60
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage =
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percentage of voltage imbalance.
% Voltage Imbalance
IFM
TYPE
=
681

=
227
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.
% Voltage Imbalance
max voltage deviation from average voltage
average voltage
224 + 231 + 226

227
= 1.76%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric
utility company immediately.

Example: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage =
*Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percentage of voltage imbalance.

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric
utility company immediately.

TYPE
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.

Cooling
Economizer Control
If the economizer is available for cooling, the unit will always try
to meet demand using the economizer before turning on a
compressor. The economizer is available for cooling when:
S The outdoor temperature is below the Economizer High
Temperature Lockout (ECL.H) and above the Economizer
Low Temperature Lockout (ECL.L)
S The outdoor enthalpy is low. If the economizer is not available
for cooling, the economizer will move to the Economizer
Minimum Position (MIN.P).
If the economizer is available for cooling and yet it is unable to
meet demand, the unit will continue to modulate the economizer
while cycling the compressors to increase total cooling capacity.
If the indoor fan is not operating, the economizer will be closed.
The 48PG units can also be equipped with optional CO2 sensors
for additional indoor air quality control. Consult the Controls and
Troubleshooting Guide for more information on IAQ features.
Cooling Using Space Sensor (T55 or T56) Control
To operate the unit in Space Sensor mode, Unit Control Type must
be set to Space Sensor (3) and a wire must be added between R and
W1 on TB1 (see controls schematic). While in this mode, the unit
tries to maintain the Space Temperature (SPT) at one of 4 different
set points: the Occupied Cool Set Point (OCSP), the Unoccupied
Cool Set Point (UCSP), the Occupied Heat Set Point (OHSP), or
the Unoccupied Heat Set Point (UHSP). The building’s occupancy
is affected by a number of different factors (see Controls and
Troubleshooting Guide for details). When the building is occupied,
the occupied set points are active. When the building in
unoccupied, the unoccupied set points are active. In Space Sensor
mode, the control will switch automatically between cooling and
heating to maintain temperature. However, to minimize
unnecessary cool to heat and heat to cool changes, there is a
10--minute delay after the last stage turns off before the control will
switch modes.
195
48PG
NOTE: The 48PG units have 1 or 2 stages of gas heat.
When the thermostat calls for heating, power is sent to W on the
IGC (integrated gas unit controller) board. An LED (light--emitting
diode) on the IGC board will be on during normal operation. A
check is made to ensure that the rollout switch and limit switch are
closed and the induced--draft motor is running. The induced--draft
motor is then energized, and when speed is proven with the hall
effect sensor on the motor, the ignition activation period begins.
The burners will ignite within 5 seconds.
If the burners do not light, there is a 22--second delay before
another 5--second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out. To
reset the control, break 24--v power to the thermostat.
When ignition occurs the IGC board will continue to monitor the
condition of the rollout and limit switches, the hall effect sensor, as
well as the flame sensor. If the unit is controlled through a room
thermostat set for fan auto., 45 seconds after ignition occurs, the
indoor--fan motor will be energized (and the outdoor--air dampers
will open to their minimum position). If for some reason the
overtemperature limit opens prior to the start of the indoor fan
blower, on the next attempt, the 45--second delay will be shortened
to 5 seconds less than the time from initiation of heat to when the
limit tripped. Gas will not be interrupted to the burners and heating
will continue. Once modified, the fan on delay will not change
back to 45 seconds unless power is reset to the control.
On units with 2 stages of heat, when additional heat is required,
W2 closes and initiates power to the second stage of the main gas
valve. When the thermostat is satisfied, W1 and W2 open and the
gas valve closes, interrupting the flow of gas to the main burners. If
the call for W1 lasted less than 1 minute, the heating cycle will not
terminate until 1 minute after W1 became active. If the unit is
controlled through a room thermostat set for fan auto., the
indoor--fan motor will continue to operate for an additional 45
seconds then stop. If the overtemperature limit opens after the
indoor motor is stopped within 10 minutes of W1 becoming
inactive, on the next cycle the time will be extended by 15 seconds.
The maximum delay is 3 minutes. Once modified, the fan off delay
will not change back to 45 seconds unless power is reset to the
control.
A LED indicator is provided on the IGC to monitor operation. The
IGC is located by removing the heat section side panel. During
normal operation, the LED is continuously on.
For units with economizers, the outdoor--air damper stays at the
Economizer Minimum Position while the evaporator fan is
operating. The outdoor--air damper is closed when the indoor fan is
not operating.
IGC LEd Indications
48PG
To maintain temperature while cooling, the unit will turn on
compressors as needed when the economizer is either unavailable
or not providing enough cooling. The minimum on--time for each
compressor is 3 minutes and the minimum off--time is 5 minutes.
Units with 1 compressor (48PG03--07) have 1 stage of cooling.
Units with 2 compressors (48PG08--14) have 2 stages of cooling.
Units with 3 compressors (48PG16) have 2 stages of cooling. The
economizer is not considered a stage of cooling even though it can
provide cooling in certain situations. In general, the minimum time
between increasing stages (from 1 to 2 and from 2 to 3) is 7.5
minutes, however, the minimum time between stages can be further
reduced in certain situations (see Controls and Troubleshooting
Guide). The minimum time between decreasing stages (3 to 1 and
2 to 0) is 5 minutes.
Consult the Controls and Troubleshooting Guide for additional
information on configuring the controls for space sensor control
and adjusting the minimum compressor on--time, minimum
compressor off--time, and the minimum time between decreasing
stages.
Cooling Using Thermostat Control
Thermostat cooling begins when the Y1 input is energized. If the
economizer is available for cooling, the economizer will try to
maintain the Supply Air Temperature (SAT) at either the Low Cool
Supply Air Set Point (LCS) for a Y1 call or the High Cool Supply
Air Set Point (HCS) for a Y2 call. If the economizer operates at
100% for 5 minutes or the economizer cooling is not available, the
unit will begin to stage compressors. While the compressors are
operating, the economizer will try to maintain its position at 100%.
However, if low suction pressures are experienced, the economizer
will begin to close in order to protect the compressors from
damage.
Three different compressor--staging algorithms are available with
ComfortLinkt control. They are called Adaptive, 1--stage Y1 and
2--stage Y1. In Adaptive mode, once compressor staging begins
(see above), at least one compressor will run as long as there is a
Y1 call. On a three--circuit machine with only a Y1 call, the second
circuit will cycle depending upon the trend in the supply--air
temperature (SAT). If there is a Y2 call, compressors will stage up
to the maximum number available.
The 1--stage Y1 and 2--stage Y1 modes are identical if there are
only two circuits. In both cases, the stages follow the thermostat
calls directly. For either mode, all stages will operate immediately
if there is a Y2 call.
If fan request G is energized, but Y1 is not energized, the indoor
fan will operate and the economizer position will be maintained at
MIN.P.

Optional Humidi--MiZert Dehumidification
System
Units with the factory--equipped Humidi--MiZer option are capable
of providing multiple modes of improved dehumidification as a
variation of the normal cooling cycle. The Humidi--MiZer option
includes additional valves in the liquid line and discharge line of
each refrigerant circuit, a small reheat condenser coil downstream
of the evaporator, and MotormasterR variable--speed control of
some or all outdoor fans. Operation of the revised refrigerant
circuit for each mode is described below.
NOTE: x = refrigerant circuit A, B, or C.
48PG03--16
Normal Cooling
Refrigerant flows from the outdoor condenser through the
normally open Cooling Valve (CV.x) to the expansion device.
Reheat1 Valve (RH1.x) and Reheat2 Valve (RH2.x) are closed.
Reheat1 (Subcooling Mode) - 48PG03-- 16
This mode increases latent cooling and decreases sensible cooling
compared to normal cooling. Refrigerant flows from the outdoor
condenser, through the normally open Reheat1 Valve (RH1.x), and
through the reheat condenser coil to the expansion device. Cooling
Valve (CV.x) and Reheat2 Valve (RH2.x) are closed.
Reheat2 (Hot Gas Reheat Mode) - 48PG03-- 16
This mode provides maximum latent cooling with little to no
sensible capacity. This mode can operate to provide
dehumidification when there is no cooling demand. Like Reheat1
mode, refrigerant flows from the outdoor condenser, through the
normally open Reheat1 Valve (RH1.x), and through the reheat
condenser coil to the expansion device. The Cooling Valve (CV.x)
is closed. Reheat2 Valve (RH2.x) is open which provides some
compressor discharge gas to the reheat condenser to further
increase the reheat of the evaporator airstream.

Normal Cooling
Refrigerant flows from the outdoor condenser through the
de--energized 3--way (RH1.x) to the expansion device. Reheat2
Valve (RH2.x) is closed.
Reheat1 (Subcooling Mode)
This mode increases latent cooling and decreases sensible cooling
compared to normal cooling. Refrigerant flows from the outdoor
condenser, through the energized 3--way Valve (RH1.x), and
through the reheat condenser coil to the expansion device. Reheat2
Valve (RH2.x) is closed.
Reheat2 (Hot Gas Reheat Mode)
This mode provides maximum latent cooling with little to no
sensible capacity. This mode can operate to provide
dehumidification when there is no cooling demand. Like Reheat1
mode, refrigerant flows from the outdoor condenser, through the
energized 3--way Valve (RH1.x), and through the reheat condenser
coil to the expansion device. Reheat2 Valve (RH2.x) is open which
provides some compressor discharge gas to the reheat condenser to
further increase the reheat of the evaporator airstream.
Units with multiple circuits can operate with additional staging of
the cooling and dehumidification capacity. When there is only
cooling demand, based on a space temperature sensor or
thermostat, one or more circuits will operate in normal cooling
mode. When there is only dehumidification demand, based on a
space humidity sensor or switch, all circuits will operate in Reheat2
mode. When there is both cooling demand and dehumidification
demand, all circuits will operate in either Reheat1 or Reheat2
mode, with the portion of Reheat1 circuits determined from the
cooling demand.
Outdoor fan control for Humidi--MiZert system units includes a
Motormaster variable--speed control of some or all outdoor fans,
depending on unit model size. The Motormaster control
automatically adjusts the outdoor fan speed to maintain
approximately 80_ to 100_F condenser temperature for circuit A at
all outdoor ambient temperatures. Some model sizes have
additional on/off staging of some outdoor fans. This staging is
controlled by both outdoor temperature and condenser coil
temperature.
Compressor staging control for Humid--MiZer units requires that
circuit A always operate when either circuits B or C are on. This
applies to normal operation, service test, and for control alarm
responses. This operation difference is required due to the fact that
the Motormaster outdoor fan control senses circuit A only.

APPLICATION DATA
Ductwork
Ductwork should be attached to the curb on all units. Interior
installation may proceed before unit is set in place on roof. If
ductwork will be attached to the unit, do not drill in condensate
drain pan area -- leaks may result.
Thru--the--Bottom Service Connections
Roof curb connections allow field power wires and control wires to
enter through the roof curb opening and bottom of unit.
Thermostat/Space Temperature Sensor (T55, T56,
or T58)
IMPORTANT: The minimum heating cfm must be maintained to
ensure proper operation in the Heating mode. The minimum
heating cfm value takes precedence over the minimum cooling cfm
value.
Minimum Ambient Cooling Operation
Temperature
All units with ComfortLinkt controls are designed to operate at
outdoor temperatures down to 0_F. Electromechanical operation
down to 40_F.
Maximum Operating Outdoor--Air Temperature
Either a 2--stage cooling thermostat or a space temperature sensor is
required for all units. A field--supplied jumper is required when
using a space temperature sensor. The jumper is placed between
terminals R and W1 on the unit thermostat terminal block (TB1 or
TB2). Refer to wiring diagram for details.
For cooling, this temperature is 125_F. Refer to the Cooling
Capacity tables for further details.
Heating--to--Cooling Changeover
Minimum Heating Entering Air Temperature
All units are automatic changeover from heating to cooling when
automatic changeover thermostat and subbase or space temperature
sensors are used.
Airflow
Units are draw--thru on cooling and blow--thru on heating.
Maximum Airflow
To minimize the possibility of condensate blow--off from
evaporator, airflow through units should not exceed 500
cfm/nominal ton.
Minimum Airflow
The minimum airflow for cooling is 300 cfm/nominal ton.
Operation Air Quantity Limits table for minimum airflow cfm for
heating.
High Altitude
A change to the gas orifice may be required at high altitudes. Refer
to Altitude Compensation charts.
The minimum temperature of air entering the dimpled heat
exchanger is 50_F continuous and 45_F intermittent for aluminum
heat exchangers and 40_F continuous and 35_ F intermittent for
stainless steel heat exchangers. To operate at lower mixed--air
temperatures, a field--supplied outdoor--air thermostat must be used
to initiate both stages of heat when the temperature is below the
minimum required temperature to ensure full fire operation. Wire
the outdoor--air thermostat (part no. HH22AG106) in series with
the second stage gas valve as shown below. Set the outdoor--air
thermostat at 35_F for stainless steel heat exchangers or 45_F for
aluminum heat exchangers. This temperature setting will bring on
the second stage of heat whenever the ambient temperature is
below the thermostat set point. Indoor comfort may be
compromised when heating is initiated using low entering air
temperatures with insufficient heating temperature rise.

OUTDOOR AIR
Wiring of Outdoor--Air Thermostat
E--Coated aluminum--fin coils undergo a precisely controlled
scientific process that bonds an impermeable epoxy coating to the
specially prepared fin coil surface. E--Coating produces a smooth,
consistent coating that is less brittle, more resilient and more
durable than previous postcoating processes. E--Coated
aluminum--fin coils offer economical protection and improved coil
life in industrial and combined coastal and industrial environments.
E--Coated copper--fin coils provide maximum protection in
virtually all environments, this option combines the continuous,
impenetrable barrier of the E--Coating process with the natural
resistance of an all--copper construction. E--Coated copper--fin coil
assemblies ensure long life in severe coastal conditions.

Motor Data
Indoor Air Quality
Due to Carrier’s internal unit design (draw--thru over the motor),
air path, and specially designed motors, the full horsepower
(maximum continuous bhp) listed in the Physical Data table and
the notes following each Fan Performance table can be utilized
with extreme confidence.
Using Carrier motors with the values listed in the Physical and Fan
Performance Data tables will not result in nuisance tripping or
premature motor failure. The unit warranty will not be affected.
An indoor air quality sensor, which senses CO2, is a
factory--installed option. The sensor in conjunction with the
economizer is used to maintain indoor air quality. By selecting this
option, the minimum economizer position can be reduced because
the control will adjust economizer position to maintain indoor air
quality to the desired set point. A wall--mounted indoor air quality
sensor is a field--installed accessory.
Enthalpy Sensor
Condenser coil protection (Enviro--Shieldt)
Enthalpy switches are available as field--installed accessories. If
only one switch is used, it is used to measure return air enthalpy. If
two switches are used they should be wired in a differential
configuration to measure the difference in the return and outdoor
enthalpies. The enthalpy switches signify when the outdoor air is
suitable for free cooling.
Pre--coated aluminum--fin coils have a durable epoxyphenolic
coating applied to the fin prior to the fin stamping process to
provide protection in mildly corrosive coastal environments.
Pre--coated coils have an inert barrier between the aluminum fin
and copper tube. This barrier electrically disconnects the dissimilar
metals to minimize the potential for galvanic corrosion. This
economical option provides substantial corrosion protection for
mild coastal environments beyond the standard uncoated coil
construction.
Copper--fin coils provide increased corrosion resistance in
moderate coastal environments where industrial air pollution is not
present. All copper coils eliminate bi--metallic construction to
eliminate the potential for galvanic corrosion. Use of copper fin
coils in industrial environments is not recommended due to
potential attack from sulfur, sulfur oxide, nitrogen oxides, carbon
and several other industrial air--borne contaminants. In moderate
seacoast environments, copper--fin coils have extended life
compared to standard or pre--coated aluminum--fin coils.
Plugged Filter Indicator
A plugged filter indicator (filter status switch) is available as a
factory--installed option and a field--installed accessory. By
measuring the pressure differential across the evaporator section, it
signals when the evaporator filters should be cleaned.
Fan Status
A fan status switch is available as a factory--installed option and a
field--installed accessory. By sensing the pressure differential
generated by the indoor fan, it signals the ComfortLinkt system
when the indoor fan blower is operating and therefore it is very
useful for detecting broken belts, etc.
