The ducts are attached directly to the roof curb to allow all ductwork to be completed before the unit is positioned.
Dedicated horizontal units (558H and 580H) are ideal for replacement or applications such as through-the-wall jobs or jobs
where sound must be attenuated before the duct penetrates the
roof. Ducts connect directly to the unit. Horizontal units may be
curb or slab mounted.

DESIGN FLEXIBILITY
Dedicated vertical supply/return units (558G and 580G) are
ideal for new construction or retrofit to existing installations. The
low unit profile is maintained when the unit is installed on the accessory roof curb, which is approved by the National Roofing
Contractors Association (NRCA). The roof curb is made watertight by the roofer.

INTEGRATED GAS UNIT CONTROLLER (IGC) (Gas Heating
Units Only) — The IGC also contains burner control logic for
accurate and dependable gas ignition. The light-emitting diode
(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.
Form No. PDS 558G,H.240.2B
INSTALLATION/SERVICEABILITY — Dedicated design (vertical or horizontal) requires no alteration time to convert in the
field. Single point electrical connections are standard on all
units. Electrical service access can be made through roof curb
or side of unit.
High static capability of standard units minimize the need to
convert to higher static, oversized motors. The unit is less sensitive to distribution ductwork design.
The standard microprocessor controls replace the need for field
installed anti-short cycle timers. The controls are compatible
with a conventional thermostat with no need to install an accessory interface. In addition, no special tools are required to run
the unit through its operational steps. It’s as simple as throwing
a DIP (dual in-line package) switch to activate the automatic test
mode. After the test cycle, the unit automatically returns to normal operation.
Hinged access panels are located for easy access to standard
serviceable components for maintenance. No fasteners need to
be removed, which reduces servicing time and prevents roof
leaks caused by discarded screws.
Color coded wiring permits easy tracing and diagnostics.
The thermal insulation contains an EPA (Environmental Protection Agency) registered immobilized antimicrobial agent to inhibit the growth of bacteria and fungi.
The IGC control board provides built-in diagnostic capability. An
LED simplifies troubleshooting by providing visual fault notification and system status confirmation.
The IGC also contains exclusive anticycle protection for gas
heat operation. After 4 continuous 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.
QUALITY AND RELIABILITY — Dual serviceable, semihermetic compressors on intertwined evaporator coil ensures
excellent full and part load efficiency. Dual refrigerant circuits,
both electrically and mechanically independent, provide
standby capability should one circuit require service. Reliable
Carlyle 06D/E compressors are proven performers.
Solid core dessicant filter driers are sized at 30 cubic in. to assure longer compressor life. Solid core filters prevent erosion
and dispersion of dessicant.
Totally enclosed outdoor-fan motors ensure many years of
trouble-free operation.
Positive-locking bearings for the indoor fan ensure vibrationfree operation of the supply fan assembly and remain locked
during the life of the bearing.
FACTORY-INSTALLED ECONOMIZER (STANDARD) — All
units come equipped with an integrated economizer which permits cooling utilizing an outdoor air sensor. The direct gear
driven, low leakage blades eliminate conventional interblade
linkages and the associated adjustments.
The economizer operates in conjunction with mechanical cooling when required and is factory-installed for either vertical or
horizontal operation. The factory-supplied and field-installed
rain hood/filter assembly prevents moisture or objects from entering the unit.
Exhaust air relief is available for all units as barometric relief or
power exhaust.
Field-adjustable set points on modulating power exhaust prevent space pressurization problems. Factory-installed relief options are unit mounted on downflow units. Accessories must be
duct mounted for horizontal applications.

NOTES:
1. Ratings are approved for altitudes to 2000 feet. At altitudes over 2000 ft,
ratings are 4% less for each 1000 ft greater than 2000 ft above sea level.
2. At altitudes up to 2000 ft, the following formula may be used to calculate
air temperature rise:
Output capacity
Dt =
1.10 x air quantity
3. At altitudes above 2000 ft, the following formula may be used:
Output capacity
Dt =
(.24 x specific weight of air x 60) (air quantity)
4. Minimum allowable temperature of mixed air entering the heat exchanger during half-rate (first stage) operation is 50 F. There is no minimum mixture temperature limitation during full-rate operation.
5. Unit is ETL listed to UL standard 1995.
6. The minimum heating cfm is typically lower than the minimum cooling
cfm on constant volume units (see Cooling Performance tables). To operate at the lower cfm requires the addition of unloaders to the lead compressor. Without this modification, the unit may not be operated below
the minimum cooling cfm.

POWER EXHAUST FANS
HEAD PRESSURE CONTROL
When combined with the economizer, the power exhaust can be used to
exhaust the return air and eliminate over-pressurization of the building.
The power exhaust utilizes multiple forward-curved fans, each driven by
its own motor.
The constant volume power exhaust stages the motors according to
economizer position to control the building pressure.
NOTE: The factory mounted power exhaust/barometric relief is shipped
tilted into the unit cabinet. Power exhaust/barometric relief is fully
assembled and only needs to be rotated into operating position for
start-up.
The standard units are designed to operate in cooling at outdoor temperatures down to 35 F. With accessory Motormaster III control (condenser fan speed modulation) 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. Refer to price pages or
contact your local representative for appropriate accessory combinations for desired outdoor ambient temperature operation.

ELECTRIC HEATER
CO2 SENSOR
Electric heaters are available in a wide range of capacities for factory
or field installation.
This sensor monitors building interior or return air carbon dioxide levels and automatically activates the outdoor fan and opens the economizer for rapid dilution of CO2 levels above an adjustable set point.
ENTHALPY CONTROL FOR
INTEGRATED ECONOMIZER
ELECTRONIC PROGRAMMABLE THERMOSTAT
C7400
A1004
+
Enthalpy economizer controls help provide efficient, economical
economizer operation. Solid-state enthalpy control includes the logic
and one sensor to calculate both dry and wet bulb of the outdoor air
to provide an accurate enthalpy reading. It then decides when to energize the economizer based on this reading. A second sensor provides information for comparison of outdoor temperature and
humidity to return-air temperature and humidity and determines the
most economical mixture of air (purchased in addition to first solidstate enthalpy sensor for differential enthalpy sensing).
The electronic programmable thermostat provides efficient temperature control by allowing programming of heating and cooling set
points with provisions for weekends and holidays.

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.
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%.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v and 480 v. If
power distribution voltage to unit varies from rated heater voltage, heater kW will
vary accordingly.
†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.
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.

CONTROLS
If thermostats are used to energize the G input, the control module will turn on the indoor fan without delay and open the economizer dampers to minimum position. If thermostats are used to
deenergize the G input, the control module will turn off the indoor fan without delay and close the economizer dampers.
When cooling, G must be energized before cooling can operate.
The control module determines if outdoor conditions are suitable for economizer cooling using the standard outdoor air thermistor. For the economizer to function for outside air cooling: the
enthalpy must be below the enthalpy set point; the outdoor-air
temperature must be equal to or less than the High Outdoor Air
Temperature Lockout (default is 65 F); the SAT (supply-air temperature) thermistor must not be in alarm; and the outdoor air
reading is available. When these conditions are satisfied, the
control module will use economizer as the first stage of cooling.
When Y1 input is energized, the economizer will be modulated
to maintain SAT at the defined set point. (The default is 55 F.)
When SAT is above the set point, the economizer will be 100%
open. When SAT is below the set point, the economizer will
modulate between minimum and 100% open position. When Y2
is energized, the control module will turn on compressor no. 1
and continue to modulate the economizer as described above.
If the Y2 remains energized and the SAT reading remains above
the set point for 15 minutes, compressor no. 2 will turn on. If Y2
is deenergized at any time, only the last stage of compression
that was energized will be turned off. If outdoor conditions are
not suitable for economizer cooling, the economizer will go to
minimum position and cycle compressors no. 1 and 2 based on
demand from Y1 and Y2 respectively. The compressors will be
locked out when the SAT temperature is too low (less than 40 F
for compressor no. 1 and less than 45 F for compressor no. 2).
After a compressor is locked out, it can restart after normal timeguard period.
The Time GuardT function maintains a minimum off time of
5 minutes, a minimum on time of 10 seconds, and a minimum
delay before starting the second compressor of 10 seconds.
When heating, the heat stages respond to the demand from W1
and W2 of the thermostat input. Heating and cooling will be mutually locked out on demand on a first call basis. The heating
and the cooling functions cannot operate simultaneously.
CONTROLS OPTIONS — The units, as shipped, are operable
as stand-alone units, using a standard (mechanical or electronic) 2-stage heat, 2-stage cool thermostat.
With a standard thermostat (programmable is optional), heating
and cooling operation is set by space temperature.
Features with Thermostat Control of Unit
• two-stage heating (if installed)
• two-stage cooling
• control of unit using Y1, Y2, W1, W2, and G thermostat inputs
• control of the indoor fan
• outdoor-air temperature/supply-air temperature monitoring
• control of an outdoor air condenser fan based on outdoor air
temperature
• control of modulating economizer damper to provide free
cooling when outdoor conditions are suitable, using supply-air
temperature as a control point
• provide power exhaust output to an external power exhaust
controller
• support a field test for field checkout
• control of 2 stages of constant volume power exhaust
• compressor Time GuardT override (power up and minimum
off and on times)

An electronic expansion board may be field-installed to provide
the following features:
• control of modulating economizer damper to maintain indoor
air quality (IAQ) when outdoor conditions are suitable
NOTE: The IAQ sensor must be set for current output (4 to
20 mA). This requires removing the sensor cover and moving a
jumper on the sensor.
• provide discrete inputs for fan status, filter status, field-applied
status, and demand limit
• provide an output for the external alarm light indicator
• provide power exhaust fire outputs for direct control of power
exhaust stages during fire or smoke modes
• control of smoke control modes including evacuation, smoke
purge, pressurization, and fire shutdown (non-modulating or
modulating power exhaust required)
SEQUENCE OF OPERATION
Heating, 558G,H Units — The control module is powered by
24 vac. If the unit is controlled through a room thermostat (with
FAN set to AUTO), upon a call for heat the first stage of heat is
energized, the indoor-fan motor will turn on, and the outdoor-air
damper will move to the minimum position. Upon a call for additional heat (if the unit is equipped with a two-stage heater), the
second stage of heat is energized. When the call for heat is satisfied, the heaters will deenergize. The indoor-fan motor will
also deenergize and the outdoor-air damper will move to the
closed position.
Cooling — On power up, the control module will activate the initialization software. The initialization software reads each DIP
switch to determine the unit configuration. The initialization sequence: clears all alarms and alerts; re-maps the input/output
database for Constant Volume (CV) operation; sets maximum
heat stages to 2; and sets maximum cool stages to 3. The control module reads DIP switch no. 3 and determines if the unit will
use expansion mode operation.
The TSTAT function performs a thermostat based control by
monitoring Y1, Y2, W1, W2, and G inputs. These functions control stages: cool1, cool2, heat1, heat2, and the indoor fan,
respectively.
The control module will set appropriate operating mode and fan
control. Whenever the DX (direct expansion) cooling is requested, the outdoor fan will operate.
The control module will operate economizer and run diagnostics
to monitor alarms/alerts at all times. When the optional expansion I/O board is employed, it will: perform a periodic scan and
maintain a database of expanded I/O points; perform Fire/
Smoke control (power exhaust required); perform IAQ control
and monitor the fan, filter, and field-applied status (with
accessories).
Heating, 580G,H Units — The gas heat units incorporate 2
separate systems to provide gas heat. Each system incorporates its own induced-draft motor, Integrated Gas Control (IGC)
board, 2 stage gas valve, manifold, etc. The systems are operated in parallel; for example, when there is a call for first stage
heat, both induced-draft motors operate, both gas valves are
energized, and both IGC boards initiate spark.
All of the gas heating control is performed through the IGC
boards (located in the heating section). The base module board
serves only to initiate and terminate heating operation.
27
CONTROLS (cont)
Smoke control modes — The 558/580G,H units with an optional expansion board perform fire and smoke control modes.
The expansion board provides 4 modes which can be used to
control smoke within the conditioned area. The modes of operation are fire shutdown, pressurization, evacuation, and smoke
purge.
Smoke detector — A smoke detector can be used to initiate fire
shutdown. This can be accomplished by a set of normally
closed pilot relay contacts which will interrupt power from the
24-v transformer, secondary ‘‘B’’ terminal to the control circuit
breaker (CB4). The wire that connects these two points is white
and labeled ‘‘W78.’’
The base module board is powered by 24 vac. When the thermostat calls for heating, power is sent from the base module
board to W on each of the IGC boards. An LED on the IGC
board will be on during normal operation. A check is made to ensure that the rollout switches and limit switches are closed and
the induced-draft motors are not running. The induced-draft motors are 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.
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.
When additional heat is required, W2 closes and initiates power
to the second stage of the main gas valves. When the thermostat is satisfied, W1 and W2 open and the gas valves close 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 and the outdoor-air dampers will close. 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.
NOTE: On standard gas models, the indoor fan will continue to
run 45 seconds after the call for heat has been terminated. If fire
shutdown is initiated the fan will stop immediately. No
45-second delay will occur.
The smoke detector may be mounted in the return-air duct or
the supply duct.
IAQ control — The accessory expansion board and accessory
IAQ sensor are required for IAQ control. The sensors operate
with a 4 to 20 mA signal. The 4 to 20 mA signal is connected to
T11 (+) and T12 (−) on the expansion board for the IAQ sensor,
and T13 (+) and T14 (−) on the expansion board for the OAQ
(outdoor air quality) sensor. The sensor is field-mounted and
wired to the expansion board installed in the unit main control
box. The IAQ sensor must be powered by a field-supplied 24-v
power supply (ungrounded). Do not use the unit 24-v power
supply to power the sensor.
To work properly, the IAQ sensor high and low reference points
for the sensor that is used must match the configured values.
The expansion board reacts to a 4 to 20 mA signal from the IAQ
sensor. The low reference (4 mA output) must be configured to
the minimum IAQ sensor reading. The high reference (20 mA
output) must be configured to the maximum IAQ sensor
reading.
The IAQ sensor can be configured to either low or high priority.
The priority value can be changed by the user. The default is
low.
Low priority — When the priority is set to low, the initial control
is to the IAQ set point, but the outside air damper position will
change to its minimum position when the following conditions
occur:
• When the supply-air temperature is less than the supply-air
temperature set point minus 8° F or when the supply-air temperature is greater than the supply air temperature set point
plus 5° F for 4 minutes.
• When the outdoor air quality is greater than the outdoor air
quality set point (ppm)
High priority — When the priority is set to high, the IAQ set point
controls the outside-air damper exclusively, with no regard to
comfort conditioning.
Power exhaust operation — The optional power exhaust
packages are factory- or field-installed with vertical units and
optionally installed in the return air ductwork for horizontal applications. The standard and modulating power exhaust (offered
on CV [constant volume] units with non-modulating to modulating accessory conversion kit) are the 2 packages available. The
modulating power exhaust package is equipped with a fieldadjustable static pressure controller which will control up to 4
power exhaust stages to maintain a building static pressure.
The blue sequencer located in the control box below the control
board can be adjusted by removing the covers and adjusting the
set point dial to the desired building pressure. The standard
power exhaust package controls up to 2 stages of power exhaust to maintain building pressure. These power exhaust
stages are staged according to a percentage of the economizer
damper position. The default values are 25% for Stage 1 and
75% for Stage 2.

APPLICATION DATA
1. Ductwork — Secure vertical discharge ductwork to roof
curb. Interior installation may proceed before unit is set in
place on roof. 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.
11. Minimum temperature — Minimum allowable temperature
of mixed air entering the heat exchanger during half-rate
(first stage) operation is 50 F. There is no minimum mixture
temperature during full-rate operation. Comfort conditioning
may be compromised at temperatures below 50 F.
12. Internal unit design — Due to internal unit design (drawthru over the motor), air path, and specially designed motors, the full horsepower listed in the Physical Data table
and motor limitations table can be utilized with extreme
confidence.
Using motors with the values listed in the Physical Data and
Motor Limitations tables will not result in nuisance tripping
or premature motor failure. The unit warranty will not be
affected.
2. Thru-the-curb service connections — Roof curb connections allow field power wires and control wires to enter
through the roof curb opening.
3. Thermostat — A 2-stage heating/cooling thermostat may
be used for all units.
4. Heating-to-cooling changeover — All units are automatic
changeover from heating to cooling when automatic
changeover thermostat and subbase are used.
13. Electric heat — A field-supplied 90° elbow must be
installed in the supply ductwork below the unit discharge
connection.
5. Airflow — Units are draw-thru on cooling and blow-thru on
heating.
6. Maximum airflow — To minimize the possibility of condensate blow-off from evaporator, airflow through units should
not exceed 500 cfm/ton.
14. Existing roof curbs (558/580B,E units) — The 558/
580G,H units will install on existing 558/580B,E vertical
supply and return roof curb applications. This minimizes installation expenses due to the use of the existing curb. No
additional roof penetrations or transition curbs are required.
The existing building ductwork on 558/580B,E units is connected to the unit (not the roof curb). The ductwork must
be disconnected from the existing unit prior to its removal.
The ductwork must then be cut back below the roof curb to
allow for installation of field-supplied ductwork. The fieldsupplied ductwork will transition from the existing building
ductwork to the newly installed accessory roof curb adapter
package. The accessory roof curb adapter package provides sheet metal duct connections to be installed in the existing roof curb. No connections exist in the original roof
curb since the ductwork is connected to the unit, not the
curb.
NOTE: Each installation should be evaluated to determine
if the application will accommodate the accessory roof curb
adapter package. Call Carrier Application Engineering for
more information concerning individual applications.
7. Minimum airflow — The minimum airflow for cooling is
300 cfm/ton. Refer to Heating Capacities and Efficiencies
table on page 7 for minimum airflow cfm for heating.
8. Minimum ambient cooling operation temperature — All
units equipped with factory economizers to allow free cooling at any outdoor ambient. If mechanical cooling is required, the units are designed to operate at outdoor
temperatures down to 35 F. With accessory MotormasterT
III control units can operate at outdoor temperatures down
to −20 F. Outdoor-fan motor no. 1 changeout is required for
Motormaster III applications.
9. Maximum operating outdoor-air temperature — The
maximum operating outdoor-air temperature is 115 F. Some
models will operate up to 125 F depending on model and
operating conditions.
10. High altitude — A change to the gas orifice may be required at high altitudes. Refer to Altitude Compensation
table on page 8.
