Integrated gas controller (IGC)
48TF008-014
Copyright 2001 Carrier Corporation
All ignition components are contained
in the compact IGC which is easily accessible for servicing. The IGC control
board, designed and manufactured exclusively for Carrier rooftop units, provides built-in diagnostic capability. An
LED (light-emitting diode) simplifies
troubleshooting by providing visual
fault notification and system status
confirmation.
The IGC also contains an exclusive
anti-cycle protection for gas heat operation. After 4 continuous cycles on the
unit high-temperature limit switch, the
gas heat operation is disabled, and an
Form 48TF-2PD
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. The LED is visible without
removing the unit control box access
panel. This LED fault-notification system reduces service person troubleshooting time and minimizes service
costs. The IGC also maximizes heating
efficiency by controlling evaporator-fan
on and off delays.
Quiet, efficient operation and
dependable performance
Compressors have vibration isolators
for quiet operation. Efficient fan and
motor design permits operation at low
sound levels and all 48TF004-014
units are mounted either on mounting
plate (004-007) or on an exclusive
polycore plate (008-014).
The 48TF008-014 units offer lower
utility costs through part-load operation using 2 stages of cooling.
Quiet and efficient operation is provided by belt-driven evaporator fans
(standard on all units over 5 tons). The
belt-driven evaporator-fan is equipped
with variable-pitch pulleys which allow
adjustment within the rpm ranges of
the factory-supplied pulleys.
Increased operating efficiency is
achieved through computer-designed
coils featuring staggered internally
enhanced copper tubes. Fins are
ripple-edged for strength, lanced, and
double waved for higher heat transfer.
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 California Air Quality Management Districts NOx requirement of
40 nanograms/joule or less is met on
004-006 size Low NOx models.
The extra thick Alumagard™ heat
exchanger coating provides corrosion
resistance and ensures long life.
The unsightly appearance of flue
stacks is eliminated and the effects of
wind on heating operations are diminished by the induced draft combustion
system. The inducer fan draws hot
combustion gas through the heat exchanger at the optimum rate for the
most effective heat transfer. The heat
exchanger operates under negative
pressure, preventing flue gas leakage
into the indoor supply air.
2
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.
All 48TF standard units are designed
for natural gas, but an accessory LP
(liquid propane) conversion kit is
available.
Safety is built in
All 48TF units have a flame rectification sensor to quickly sense the burner
flame and ignite burners almost immediately. 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.
Safety is also assured due to the
heating safety controls which 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 hightemperature 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 deenergizes the gas valve in
the event of a flame rollout.
Durable, dependable
construction
Designed for durability in any climate,
the weather-resistant cabinets are constructed of galvanized steel and bonderized, and all exterior panels are coated with a prepainted baked enamel finish. The paint finish is non-chalking,
and is capable of withstanding ASTM
B117 500-hour Salt Spray Test. All
internal cabinet panels are primed,
permitting longer life and a more
attractive appearance for the entire
unit.
In addition, all 48TF units are designed with a single, continuous top
piece to eliminate any possible leaks.
Totally enclosed condenser-fan motors
and permanently lubricated bearings
provide additional unit
dependability.
Easy installation and
conversion
All units are shipped in the vertical
duct configuration for fit-up to standard
roof curbs. (Two different curb sizes fit
unit sizes 004-007 and 008-014, respectively.) The contractor can order
and install the roof curb early in the
construction stage, before decisions on
size requirements are made.
All units feature roll-formed base rail
design with forklift slots and rigging
holes for easier maneuvering. (Forklift
slots are found on 3 sides for
48TF004-014 units.) The standard
48TF004-006 units have operating
weights under 500 lb and durable
packaging protects all units during
shipment and storage.

Features/Benefits (cont)
The units can be easily converted
from a vertical to a horizontal duct configuration by relocating the panels supplied with the unit.
The non-corrosive sloped condensate pan permits either an external
horizontal side condensate drain (outside the roof curb) or an internal vertical bottom drain (inside the roof curb).
Both options require an external, fieldsupplied P-trap.
The 48TF units were designed with
service technicians in mind. The
single-row condenser coils on the
48TF004 and 008 units simplify the
cleaning process. The efficient
in-shot burners and all ignition
components are contained in an
easily removable, compact assembly.
The 48TF004-014 units also have a
standard filter access panel, which permits tool-less filter changes, even on
units with horizontal economizers.
Simple electrical connections
Terminal boards, located in the base
unit control box, facilitate connections
to room thermostat, outdoor thermostat(s), and economizer. Service panels
are quickly removed, permitting easy
servicing.
Thru-the-bottom utility connection
capability allow power, control wiring,
and gas to be routed through unit base
pan, minimizing roof penetrations.
Gas, power, and control connections
are made on the same side of the unit
to simplify installation.
In addition, color-coded wires permit
easy tracing and diagnostics.
Proven compressor reliability
Design techniques feature computerprogrammed balance between compressor, condenser, and evaporator.
Carrier-specified hermetic compressors are equipped with compressor
overcurrent and overtemperature protection to ensure dependability.
All 48TF units have Carrier’s exclusive Acutrol™ metering device which
precisely controls refrigerant flow,
preventing slugging and flood-back,
while maintaining optimum unit
performance. Refrigerant filter driers
are standard.
Integrated economizers and
outdoor air
Optional economizers and manual
outdoor-air dampers introduce outdoor
air which mixes with the conditioned
air, improving indoor-air quality and often reducing energy consumption.
During a first stage call for cooling, if
the outdoor-air temperature is below
the economizer control changeover
set point, the discharge-air sensor
modulates the economizer outdoor-air
damper open to take advantage of free
cooling provided by the outside air.
When second-stage cooling is called
for, the compressor is 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 vent position. Durablade economizer operation is controlled by a dry-bulb thermostat that
senses outdoor-air temperature.
Accessory upgrade kits allow for
either outdoor air enthaply changeover
or for more precise differential
enthalpy control.
The Durablade economizer (option
or accessory) on the 48TF004-014
units has a reliable sliding plate damper
which is easily adjusted for 100% outdoor air, 100% return air, or any
proportions of mixed air.
The 48TF004-014 units can
also utilize the factory or field-installed
EconoMi$er. The EconoMi$er is
microprocessor controlled and incorporates a parallel, opposed-blade gear
driven damper system. In addition, it
has a spring return built into the damper actuator to provide reliable close-onpower-loss. The EconoMi$er comes
equipped with up to 90% barometric
relief capability for high outdoor airflow applications.
In addition, the EconoMi$er twostage power exhaust accessory can be
utilized to help maintain proper building pressure.
For units without economizer, yearround ventilation is enhanced by a
manual outdoor-air damper (ordered as
an accessory or an option). The damper can be preset to admit up to 50%
outdoor air.
Carrier PremierLink™ controls add reliability, efficiency,
and simplification
The PremierLink direct digital controls
can be ordered as a factory-installed
option or as a field-installed accessory.
Designed and manufactured exclusively
by Carrier, the controls can be used to
actively monitor and control all modes
of operations, as well as monitor the
following diagnostics and features: unit
number, zone temperature, zone set
point, zone humidity set point,
discharge-air temperature, outdoor humidity level, filter status, fire shutdown
status, IAQ set point, enthalpy status,
differential enthalpy status, heat/cool
lockout, CFM set point, pre-occupancy
purge, economizer controls and early
morning warm-up.
This controller has a 38.4K Baud
communications capability and is compatible with ComfortLink™ controls,
CCN and ComfortVIEW™ software. The
Scrolling Marquee and Navigator are optional tools that can be used for programming and monitoring the unit for optimal
performance. The addition of the Carrier
CO2 sensor in the conditioned space
provides ASHRAE 62-99 compliance
and Demand Control Ventilation.
The PremierLink peer-to-peer,
Internet-ready communicating control is
designed specifically for Constant Volume and Variable Volume and Temperature applications. This comprehensive
controls system allows all Carrier 3 to
25 ton rooftops to be daisy chained
together on a roof to create a fully functional HVAC (heating, ventilation and
air conditioning) automation system.
Carrier Apollo controls
The Apollo communicating controls
are factory-installed into the rooftop
unit control box, and come equipped
with built-in diagnostic capabilities.
Light-emitting diodes (LEDs) simplify
troubleshooting by indicating thermostat commands for both stages of heating and cooling, evaporator fan operation, and economizer operation. The
Apollo communicating controls are designed to work specifically with the
Carrier TEMP and VVT® (variable volume and temperature) thermostats.
The Apollo controls allow the use of an
IAQ (Indoor-Air Quality) sensor. The
Apollo controls, combined with Carrier
thermostats, incorporate a 5-minute
recycle delay timer between modes of
operation to prevent short cycling.
Indoor-air quality begins with
Carrier rooftops
Sloped condensate pans minimize
biological growth in rooftop units in
accordance with ASHRAE (American
Society of Heating, Refrigeration, and
Air Conditioning Engineers) Standard
62. Two-inch filters with optional dirty
filter indicator switch provide for
greater particle reduction in the return
air. The face-split evaporator coils
improve the dehumidification capability of standard units, maximize building
humidity control.
Optional proportional reacting
CO2 sensor is available with the
EconoMi$er to aid the IAQ benefits.

Energy$Recycler — the IAQ
solution for today’s “tight”
buildings
Indoor-air quality (IAQ) generally refers
to the level of pollutants inside a building. These pollutants include cigarette
smoke, carbon dioxide exhaled by
occupants, radon gas, car exhaust,
paint fumes, and odors.
Concern over increased indoor air
pollutants has been spurred by several
issues: 1) changes in new building
construction methods and retrofit of
older buildings have reduced air
4
infiltration rates; 2) Synthetic materials
release airborne particles, odors, and
chemicals; and 3) HVAC systems that
bring in minimal fresh air.
Indoor-air quality concerns caused
ASHRAE to recommend increased
ventilation for all public buildings.
Simply introducing fresh air into a
building, however, is not always
practical or cost effective. Additional
ventilation can overload HVAC
systems and increase energy costs.
Carrier’s 62AQ Energy$Recycler
unit solves this dilemma by providing
increased fresh air while keeping
increased costs to a minimum. In
addition, the Energy$Recycler helps
reduce humidity levels, which helps to
prevent deterioration of building
materials and retards the growth of
mold and mildew.
The 62AQ Energy$Recycler unit
provides the best solution to retaining
the energy-conserving benefits of today’s tighter building construction
while improving indoor-air quality.

LOW AMBIENT CONTROLS
CARRIER COMMERCIAL THERMOSTAT
The 48TF004-014 standard units are designed to
operate in cooling at outdoor temperatures down
to 25 F. With accessory Motormaster IV control
(condenser-fan cycling) units can operate at outdoor temperatures down to –20 F. The head
pressure controls, which mount in the condenser
section, control the condenser-fan motor to maintain correct condensing temperature.
Designed specifically for use with Carrier commercial systems, this Carrier
programmable thermostat features LED occupied/unoccupied displays and
setback mode which can override continuous fan operation.
LIGHT COMMERCIAL THERMIDISTAT
The Light Commercial Thermidistat combines temperature and humidity
control in one device.
TIME GUARD II CONTROL
MOTORMASTER IV CONTROL
Time Guard II control automatically prevents compressor from restarting for
at least 5 minutes after a shutdown. Accessory prevents short cycling of
compressor if thermostat is changed rapidly. Time Guard II control mounts
in the control compartment of unit.

LIQUID PROPANE (LP) CONVERSION KITS
DURABLADE ECONOMIZER
004-007 SHOWN
The LP conversion kit allows the unit to utilize a liquid propane fuel
supply in areas where natural gas is unavailable, and permits the unit
to be converted from natural gas to LP gas use. The kit contains the
orifices required for LP operation.
ECONOMI$ER
CONTROLLER
Exclusive Durablade economizer damper design saves energy while
providing economical and reliable cooling. A sliding plate on the face
of the economizer controls the amount of outdoor air entering the
system. Closed, it provides a leakproof seal which prevents ambient
air from seeping in or conditioned air from seeping out. It can be
adjusted easily for 100% outdoor air or any proportions of mixed air.
Like the base unit, the economizer is converted easily for horizontal
discharge applications.
ELECTRONIC PROGRAMMABLE
THERMOSTAT
WIRING HARNESS
OUTDOOR AIR
BLOCK-OFF PLATE
Factory-installed EconoMi$er utilizes a microprocessor-based control, gear drive damper system, low pressure drop characteristics,
built-in spring return (for close upon power loss), and an integral
barometric damper.
NOTE: EconoMi$er is available for vertical ductwork applications
factory installed. A horizontal EconoMi$er is available for field
installation.
Carrier’s electronic programmable thermostat provides efficient
temperature control by allowing you to program heating and
cooling setbacks and setups with provisions for weekends and
holidays. Accessory remote sensing package is also available to
provide tamperproof control in high traffic spaces. Used in conjunction with factory-installed Apollo control, this thermostat provides a 5-minute recycle timer between modes of operation for
short-cycle protection.
CONVENIENCE OUTLET
POWER EXHAUST
Power exhaust replaces the
standard exhaust hood to
reduce zone pressurization
and increase fresh air circulation. The two-stage fan
system is another easy-toinstall way to optimize rooftop performance.

Factory-installed, internally mounted
and externally accessible 115-v female
receptacle. Includes 15-amp GFI
(Ground Fault Interrupter) receptacle
with independent fuse protection. Voltage required to operate convenience
outlet is provided by a factory-installed
transformer.
FACTORY-INSTALLED APOLLO
COMMUNICATING CONTROLS
UNIT-MOUNTED DISCONNECT
The Apollo direct digital controls are designed exclusively by Carrier,
and are used to actively monitor and control all modes of operation
as well as to monitor evaporator-fan status, filter status, supply-air
temperature, outdoor-air temperature, indoor-air quality, and fieldprovided sensors. They are designed to work in conjunction with
Carrier TEMP and VVT® (variable volume/variable temperature)
system thermostats.
Factory-installed, internally-mounted, NEC (National Electrical
Code) and UL (Underwriters’ Laboratories) approved non-fused
switch provides unit power shutoff with disconnect lockout protection
capability. The switch is accessible from outside the unit.
PREMIERLINK™ CONTROL
The PremierLink peer-to-peer, Internet ready communicating control is designed specifically for constant volume and variable volume and temperature applications. This comprehensive control system allows all Carrier 3 to 25 ton rooftops to be daisy-chained together on a roof to create a
fully functional HVAC automation system.

Determine fan speed and power requirements
at design conditions.
Before entering the Fan Performance tables, calculate
the total static pressure required based on unit component. From the given and the Accessory/FIOP
Static Pressure of the 48TF find:
External static pressure supply
0.6 in. wg
External static pressure return
0.2 in. wg
Accessory static — None
0.0 in. wg
Total Static
0.8 in. wg
Enter the Fan Performance table for vertical
discharge units of the 48TF006 at 0.80 in. wg at
2000 cfm. The standard motor will provide 0.73 ESP
at high speed. This does not meet the required ESP of
0.8 in. wg. Choose the alternate motor. The alternate
motor rpm is 1227, Bhp is 1.40, and Watts is 1431.
NOTE: Convert to Fan Heat using the formula below.
Indoor Fan Heat = watts x 3.413 Btuh/watt
= 1431 x 3.413 = 4884 Btuh
Select Energy$Recycler based on Outdoor
Entering Cfm.
Entering the Energy$Recycler Product Data literature,
see the Cooling Ratings table in the Capacities section. At 450 cfm entering outdoor airflow, choose
Model 62AQ060.
Using 450 cfm outdoor supply airflow, 95 F OD DB,
and 75 F OD WB find performance of the 62AQ060
at these conditions:

IV Using the simplified* method below, calculate
the approximate mixed air temperature for the
rooftop unit evaporator coil.
Using the outdoor-air entering cfm, the room cfm and
the room exhaust airflow with their respective db and
wb temperatures, determine the db and wb entering
the rooftop evaporator coil.
a) Estimate the mixed air db to the evaporator coil.
t mix db = ((cfm oa x t oa db) + ((cfm ra – cfm exh)

Mixed air temperature into the rooftop evaporator
= 65.40 F wb
*Simplified method of determining wet bulb (wb)
temperature of mixture. This approximation is
used because the wb lines in the area of the psychrometric chart in the area used in the calculation is relatively linear, providing a close approximation. A more accurate solution can be found
using the E-Cat program.

Energy$Recycler
–13,000 Btuh
Rooftop cooling load required is
54,000 Btuh
VI Select the rooftop unit based on mixed air
entering conditions and cooling load.
Enter cooling capacity table at outdoor entering temperature 95 F, mixed air entering evaporator at
2000 cfm, 76.9 F db, and 65.4 F wb. Interpolation is
required.
The 48TF006 will provide a total gross cooling
capacity of 58,400 Btuh, a sensible cooling of
51,400 Btuh, and a kW rating of 5.69.
Since these values were not at 80 F entering db, they
were calculated based on the notes following the
Cooling Capacity tables.
NOTE: Unit ratings are gross capacities and do not
include the effect of evaporator-fan motor heat. To
calculate net capacities see Steps VII and VIII.
VII Select net heating capacity of unit to meet
design condition requirements.
Enter the Heating Capacities and Efficiencies rating
table. The 48TFD006 unit will provide 59,200 Btuh
of heating.
Enter the 62AQ060 Heating rating table at 450 cfm.
At 70 F and 0° F find the heating value for the
Energy$Recycler to be 15.2 MBtuh.
The customer heat requirement is 60,000 Btuh.

48TFD006 unit is sufficient.
VIII Determine net cooling capacity.
Cooling capacities are gross capacities and do not include indoor (evaporator) or optional Energy$Recycler
supply fan heat.
Determine net cooling capacity using the following
formula:
Net Capacity = (Gross Capacity Rooftop Unit +
Energy$Recycler) – (Indoor [evaporator] fan motor
[IFM] Heat + Optional Energy$Recycler Supply Fan
Motor Heat)

IX Determine the operating watts of the rooftop
unit and Energy$Recycler unit.
Cooling with Energy$Recycler in operation:
a) Rooftop unit:
Using the 48TF006 cooling capacity table and the
calculations described in Step VI of this procedure,
determine:
compressor watts
5,690 watts
Indoor fan motor from Step II
1,431 watts
Outdoor fan motor from Physical Data table find
1/4 hp†
Assume OD motor efficiency is 0.75.
X
Watts = (746 x hp)/(motor Eff)
= (746 x 1/4)/(0.75)
=
249 watts
†Dual circuit units will have two outdoor fans, double values.
b) Energy$Recycler:
Compressor watts from 62AQ060
Cooling Ratings table
1,060 watts
Optional supply fan from
fan curves
none selected
Exhaust fan operating watts from 62AQ060
Exhaust Fan Performance Curve at 230-v,
450 cfm, 0.2 in. wg, Static =

Total watts for the unit in operation
at design conditions
8,540 watts
Electrical data RLA, FLA, LRA, MCA and
MOCP.
Separate Power Supply:
If the 62AQ is wired for separate power see the Electrical Data table.
Single Power Supply with Unit:
The unit is 230 v-3-60 Hz, so from the 48TF Electrical Data table, find unit electrical data. For the rooftop
unit with alternate indoor fan motor the data is MCA
= 27.3 amps, MOCP = 35 amps, Min Unit Disconnect Size FLA = 27, and LRA = 128.
For this example follow the steps outlined in the
Application Data section of the Energy$Recycler
Product Data for single power supply for all rooftop
units except size 014 (230-v) and 62AQ on 460-v
power supply. For other size and voltage conditions
follow corresponding steps also outlined in the
Energy$Recycler Product Data Application data
section.
From the Single Power Supply table (Electrical Data,
Energy$Recycler Product Data) find 230 v, for
62AQ060300, “X” = 8.1 amps and “Y” = 9.3 amps.
Add “X” amps to the MCA and MOCP and add “Y”
amps to the minimum disconnect size.

(MOCP calculation is 43.1. Round the value down to
40. 40 is greater than the MCA of 35.4, therefore 40
is the correct MOCP.)
The wiring to the unit must be suitable for the MCA
calculated above.
The overcurrent protective device for the combination
load is equal to 40, thus a single disconnect may be
used for BOTH the MAIN UNIT and the 62AQ provided that the wire supplying the 62AQ is sized for a
minimum of 33% of the maximum overcurrent protection device value (i.e., 40 x .33 = 14 Amps). No
further subfusing is required.
In this example a 40-amp disconnect would be used
for the combined load of the 48TF006 and the
62AQ060 Energy$Recycler unit.

NOTES:
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)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil.
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

3. Values include losses for filters, unit casing, and wet coils. See
page 52 for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 3.7 and the maximum continuous
watts are 3313. Extensive motor and electrical testing on these
units ensures that the full range of the motor can be utilized with
confidence. Using your fan motors up to the wattage ratings shown
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected. See Evaporator-Fan Motor Performance table on page 56 for additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
6. Interpolation is permissible. Do not extrapolate.

3. Values include losses for filters, unit casing, and wet coils. See
page 52 for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 3.7 and the maximum continuous
watts are 3313. Extensive motor and electrical testing on these
units ensures that the full range of the motor can be utilized with
confidence. Using your fan motors up to the wattage ratings shown
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected. See Evaporator-Fan Motor Performance table on page 56 for additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.

*Standard motor drive range is 695 to 935 rpm. Alternate motor drive
range is 835 to 1085 rpm. All other rpms require a field-supplied drive.
NOTES:
1. Boldface indicates field-supplied drive is required.
2.
indicates optional high-static motor and drive are required.
See high-static data on next page.
3. Values include losses for filters, unit casing, and wet coils. See
page 52 for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 2.4 for the standard motor, 2.9 for the
alternate motor. Maximum continuous watts are 2120 for the standard motor, 2615 for the alternate motor. Extensive motor and
electrical testing on these units ensures that the full range of the
motor can be utilized with confidence. Using your fan motors up to

3. Values include losses for filters, unit casing, and wet coils. See page 52
for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 3.7 for the standard motor, and 5.25 for
the alternate motor. The maximum continuous watts are 3313 for the
standard motor and 4400 for the alternate motor. Extensive motor and
electrical testing on these units ensures that the full range of the motor
can be utilized with confidence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. See Evaporator-Fan
Motor Performance table on page 56 for additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
6. Interpolation is permissible. Do not extrapolate.

*Derating of the unit is not required unless the heating value of the gas exceeds the values
listed in the table above, or if the elevation exceeds 6000 ft. Derating conditions must be 4%
per thousand ft above sea level. For example, at 4000 ft, if the heating value of the gas
exceeds 1000 Btu/ft3, the unit will require a 16% derating. For elevations above 6000 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.

Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage =
=
452 + 464 + 455
3
1371
3
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
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 percent
of voltage imbalance.
% Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
58
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 1.53%
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 =
=
452 + 464 + 455
3
1371
3
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
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 percent
of voltage imbalance.
% Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
60
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 1.53%
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.

Operating sequence
Cooling, units without economizer — When thermostat calls for cooling, terminals G and Y1 are energized.
The indoor (evaporator) fan contactor (IFC) and compressor contactor no. 1 (C1) are energized, and evaporator-fan
motor (IFM), compressor no. 1, and condenser fan(s) start.
The liquid line solenoid value for compressor no. 1 is deenergized open. The condenser-fan motor(s) runs continuously while unit is cooling. For units with 2 stages of cooling, if
the thermostat calls for a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) is energized
and compressor no. 2 starts.
Heating, units without economizer — When the thermostat calls for heating, terminal W1 is energized. In order
to prevent thermostat short-cycling, the unit is locked into
the Heating mode for at least 1 minute when W1 is energized. The induced-draft motor (IDM) is then energized
20 seconds before the burner ignition sequence begins. The
indoor (evaporator) fan motor (IFM) is energized 45 seconds
after a flame is proven. On units equipped for two stages of
heat, when additional heat is needed, W2 is energized and
the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45-second time-off delay.
Cooling, units with Durablade economizer — When
the outdoor-air temperature is above the OAT (outdoor-air
thermostat) setting and the room thermostat calls for cooling, compressor contactor no. 1 is energized to start compressor no. 1 and the outdoor (condenser) fan motor
(OFM). The indoor (evaporator) fan motor (IFM) is energized and the economizer damper moves to the minimum
position. Upon a further call for cooling, compressor contactor no. 2 will be energized, starting compressor no. 2
(008-014 only). After the thermostat is satisfied, the damper moves to the fully closed position when using an auto fan
or to the minimum position when using a continuous fan.
When the outdoor-air temperature is below the OAT setting and the thermostat calls for cooling, the economizer
dampers move to the minimum position. If the supply-air
temperature is above 57 F, the damper continues to open
until it reaches the fully open position or until the supplyair temperature drops below 52 F.
When the supply-air temperature falls to between 57 F
and 52 F, the damper will remain at an intermediate open
position. If the supply-air temperature falls below 52 F, the
damper will modulate closed until it reaches the minimum
position or until the supply-air temperature is above 52 F.
When the thermostat is satisfied and the indoor-fan motor
is still in operation, the damper will move to the minimum
open setting. If the thermostat is satisfied and the indoorfan motor is deenergized, the damper will move to the fully
closed position.
If the outdoor air alone cannot satisfy the cooling requirements of the conditioned space, economizer cooling
is integrated with mechanical cooling, providing secondstage cooling. Compressor no. 1 and the condenser fan
will be energized and the position of the economizer
damper will be determined by the supply-air temperature.
Compressor no. 2 is locked out.
62
When the second stage of cooling is satisfied, the compressor and OFM will be deenergized. The damper position will be determined by the supply-air temperature.
After a 30-second delay, the IFM shuts off. If the thermostat fan selector switch is in the ON position, the IFM
will run continuously.
Cooling, units with EconoMi$er — When the outdoorair temperature (OAT) is above the ECON SP set point and
the room thermostat calls for Stage 1 cooling (R to G +
Y1), the indoor (evaporator) fan motor (IFM) is energized
and the EconoMi$er damper modulates to minimum position. The compressor contactor is energized to start the
compressor and outdoor (condenser) fan motor (OFM). After the thermostat is satisfied, the damper modulates to the
fully closed position when the IFM is deenergized.
When the OAT is below the ECON SP setting and the
room thermostat calls for Stage 1 cooling (R to G + Y1),
the EconoMi$er modulates to the minimum position when
the IFM is energized. The EconoMi$er provides Stage 1 of
cooling by modulating the return and outdoor air dampers
to maintain a 55 F supply air set point. If the supply-air
temperature (SAT) is greater than 57 F, the EconoMi$er
modulates open, allowing a greater amount of outdoor air
to enter the unit. If the SAT drops below 53 F, the outdoor
air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F, the
EconoMi$er maintains its position.
If outdoor air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the
MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below.
NOTE: Compressor has a 2-minute Minimum On, Minimum Off, and Interstage delay timer.
1. If Y1 is energized, and the room thermostat calls for
Y2 (2-stage thermostat), compressor no. 1 and OFM
are energized. The EconoMi$er damper is maintained at its current position.
2. If Y1 is energized for more than 20 minutes, and Y2
is not energized (whether or not a 2-stage thermostat
is used), compressor no. 1 and OFM are energized.
The EconoMi$er damper is maintained at its current
position.
3. If Y1 is energized, and compressor no. 1 is already
energized (see Step 2) and the room thermostat calls
for Y2, the compressor continues to operate. If Y2
remains energized for more than 20 minutes, compressor no. 2 is energized.
NOTE: Compressor no. 2 cannot be energized unless
there is a signal for Y2 from the space thermostat.
4. If compressor no. 2 is energized, and the Y2 signal
from the thermostat is satisfied, compressors 1 and 2
are deenergized. Reasserting Y2 will start compressor
no. 1 and (after a 20-minute interstage delay) compressor no. 2.
5. If compressor no. 1 is energized and the thermostat is
satisfied, compressor no. 1, the OFM, and IFM are
deenergized and the EconoMi$er modulates closed.
When the OAT is below the MECH CLG LOCKOUT set
point, the compressors remain off.
Heating, units with economizer — When the thermostat calls for heating, terminal W1 is energized. In order to
prevent thermostat short-cycling, the unit is locked into the
Heating mode for at least 1 minute when W1 is energized.
The induced-draft motor is then energized and the burner
ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited
and the damper moves to the minimum position. On units
equipped for two stages of heat, when additional heat is
needed, W2 is energized and the high-fire solenoid on the
main gas valve (MGV) is energized. When the thermostat is
satisfied and W1 is deenergized, the IFM stops after a
45-second time-off delay. The economizer damper then
moves to the fully closed position. When using continuous
fan, the damper will remain in the minimum position.
Power exhaust — When the outdoor-air damper is modulated open, the two end switches located in the actuator
are tripped. The factory settings are: switch no. 1 will close
at 30% outdoor-air; switch no 2 will close at 70% outdoorair. Both switches are field adjustable. As the outdoor-air
damper opens, switch no. 1 closes, energizing a double
pole relay that starts fan no. 1. As the outdoor-air damper
continues to open, switch no. 2 will close, energizing a
double pole relay that starts fan no. 2. When the outdoorair damper closes to a point below the fan start points
(30% fan no. 1, 70% fan no. 2), the respective fan will be
deenergized.

TEMP Systems
A TEMP System is a network of communicating Carrier
TEMP System thermostats and rooftop, factory-mounted
Apollo direct digital controls, each serving its own zone
and heating/cooling unit. Networking allows your building
manager to easily access each of your systems from a single location...whether they are in the same building or located throughout town.
TEMP SYSTEM THERMOSTAT (WITH TIMECLOCK)
The TEMP System’s inherently flexible, modular base
design supports the exact number of independent,
single zone systems you require...no more, no less, no
compromises.

Application data
Ductwork — Secure vertical discharge ductwork to roof
curb. For horizontal discharge applications, attach ductwork to unit, or field-supplied flanges can be attached to
horizontal discharge openings and all ductwork attached to
flanges.
To convert Durablade economizer from vertical discharge to horizontal discharge:
1. Remove economizer to gain access to return duct
opening.
2. Move the horizontal discharge duct opening covers to
the vertical discharge openings.
3. Rotate economizer 90 degrees (until the economizer
motor faces the condenser section).
4. Rotate the barometric relief damper 90 degrees
(economizer only).
5. Install block-off plate over the opening on the access
panel.
Thru-the-bottom utility connections — An accessory
kit is required for proper installation of thru-the-bottom
connections.
Thermostat — Use of 2-stage cooling thermostat is recommended for all units. A 2-stage cooling thermostat is
required on units with accessory economizer to provide
integrated cooling.
Heating-to-cooling changeover — All units are automatic changeover from heating to cooling when automatic
changeover thermostat and subbase are used.
Airflow — Units are draw-thru on cooling and blow-thru
on heating.
Horizontal EconoMi$er — A field-installed accessory
for horizontal discharge applications. Field-installed power
exhaust accessory also available for vertical or horizontal
EconoMi$er applications.
Power Exhaust — The power exhaust system is an accessory for the EconoMi$er system. It consists of a separate exhaust hood and a two-stage fan system.
Maximum airflow — To minimize the possibility of condensate blow-off from evaporator, airflow through units
should not exceed 500 cfm/ton.
Minimum airflow — The minimum airflow for cooling is
300 cfm/ton.
Minimum ambient cooling operation temperature — The cooling temperature for size 004-014
standard units is 25 F. With accessory Motormaster® IV
control and field-supplied wind baffles, units can operate at
outdoor temperatures down to –20 F.
Maximum operating outdoor-air temperature — For
cooling, this temperature is 115 F.
High altitude — A change to the gas orifice may be required at high altitudes. Refer to Altitude Compensation
charts on page 53.
Minimum temperature — Air entering the heat exchanger in heating must be a minimum of 50 F continuous
and 45 F intermittent.
Internal unit design — 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.
Apollo direct digital communicating controls — The
Apollo direct digital controls must be used with either a
Carrier master or monitor thermostat.
Carrier PremierLink™ Controls — The Carrier PremierLink Controls can be used with any thermostat.
