INTEGRATED GAS UNIT CONTROLLER (IGC) (All Models)
— All ignition components are contained in the compact IGC
which is easily accessible for servicing. The IGC control board,
designed and manufactured exclusively for Bryant 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 hightemperature limit switch, the gas heat operation is disabled, and
an error code is issued. This feature greatly improves reliability
of the rooftop unit.
FEATURES/BENEFITS
Every compact one-piece unit arrives fully assembled, charged,
tested, and ready to run.
Form No. PDS 580D.36.8
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 ex-
tremely quiet operation. Efficient fan and motor design permits
operation at very low sound levels and all 580D036-150 units
are mounted either on independent mounting rails (036-072) or
on an exclusive polycore plate (090-150).
The 580D090-150 and 579F180-300 units offer high energy efficiency and 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.
A standard (low-medium static) and alternate (high static) drive
is available for 579F180-300 units.
Increased operating efficiency is achieved through computerdesigned 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 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.
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 580D and 579F standard units are designed for natural gas,
but an accessory LP (liquid propane) conversion kit is available,
if required.
SAFETY IS BUILT IN — All 580D and 579F 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 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
Bryant 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, the 580D090-150 units are designed with a single,
continuous top piece to eliminate any possible leaks. Totallyenclosed condenser-fan motors and permanently-lubricated
bearings provide additional unit dependability.
EASY INSTALLATION AND CONVERSION — All units are
shipped in the vertical discharge configuration for fit-up to standard roof curbs. (Two different curb sizes fit unit sizes 036-072
and 090-150, respectively,and one curb size is needed for 180300 units.) 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 baserail design with forklift slots and
rigging holes for easier maneuvering. (Forklift slots are found on
3 sides for 580D036-150 units and on 2 sides for 180-300
units.) The standard 580D036-060 units have operating weights
under 500 lb and durable packaging protects all units during
shipment and storage.
The units can be easily converted from a vertical to a horizontal discharge configuration either by interchanging the
panels supplied with the unit (sizes 036-150) or by using
one of the horizontal supply/return adapter roof curbs (sizes
180-300).
NOTE: On units using horizontal supply and return the accessory barometric relief or power exhaust must be installed on the
return ductwork.
Convenient duct openings in the 579F180-300 unit basepans
permit side-by-side or concentric duct connections (see Application data section on page 65) without requiring internal unit
modification.
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, field-supplied P-trap. Also, the condenser coil grille (available on the 036-150 units as a fieldinstalled accessory provides a metal plate as an alternate
location for the field-supplied disconnect, if desired.
The 579F/580D units were designed with service technicians in
mind. The single-row condenser coils on the 580D036-060 and
090 units simplify the cleaning process. The efficient in-shot
burners and all ignition components are contained in an easily
removable, compact assembly.
The 580D036-150 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 service connection capability (sizes 036-150)
and thru-the-curb service connections (sizes 180-300) allow
power and control wiring to be routed through unit base pan
(036-150 units) or curb (180-300 units), minimizing roof penetrations. Both 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.
2
PROVEN COMPRESSOR RELIABILITY — Design techniques
feature computer programmed balance between compressor,
condenser, and evaporator. Hermetic (036-150 units) and semihermetic (180-300 units) compressors with suction and
discharge service valves are equipped with compressor overcurrent and overtemperature protection to ensure dependability.
Crankcase heaters (180-300 units) prevent refrigerant dilution
of oil during off cycles and ensure proper lubrication at start-up
to prolong compressor life. Crankcase heaters are not necessary on 036-150 units due to high-side crankcase design (sizes
072,150) and low refrigerant charge levels (sizes 036-150).
The 579F180 unit (with factory-supplied unloading) is equipped
with a thermostatic expansion valve to precisely adjust refrigerant flow during Stage 1 (unloaded) operation. All other 579F/
580D units have the exclusive Acutrol™ metering device which
precisely controls refrigerant flow, preventing slugging and
flood-back, while maintaining optimum unit performance.
Additional unloaders are not recommended on the 579F180300 units.
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 control changeover set point, the discharge-air
sensor modulates the economizer outdoor-air damper open to
achieve the changeover set point. 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. Economizer operation is
controlled by Accusensor™ I dry-bulb thermostat that senses
outdoor-air temperature. Accessory upgrade kits include Accusensor II solid-state enthalpy control (sizes 036-150) and Accusensor III enthalpy sensor.
The Durablade economizer (option or accessory) on the
580D036-150 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 580D036-150 units can also utilize the optional Parablade
economizer. This economizer incorporates a parallel-opposed
blade design with standard enthalpy controls. In addition, the
Parablade economizer has a spring return built into the damper
motor to provide reliable close-on-power-loss. The Parablade
economizer comes equipped with up to 45% barometric relief
capability for high outdoor airflow applications.
For units without economizer, year-round ventilation is enhanced by a manual outdoor-air damper (ordered as standard
on 579F180-300; ordered as an accessory or an option
on 580D036-150 units). The damper can be preset to admit
up to 25% outdoor air (sizes 180-300) or 50% outdoor air
(sizes 036-150).
In addition, the barometric relief damper or power exhaust
accessory can be utilized to help maintain proper building
pressure.
INDOOR-AIR QUALITY — Sloped condensate pans minimize
biological growth in rooftop units in accordance with ASHRAE
(American Society of Heating, Refrigeration, and Air Conditioning Engineers) Standard 62-89. 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, and standard enthalpy controls provided with the optional or accessory (sizes
036-150) economizers maximize building humidity control.

Accusensor economizer controls help provide efficient, economical
economizer operation. Accusensor II 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 on 036-150
units. It then decides when to energize the economizer based on this
reading. The 180-300 unit economizer provides the decision-making
function internally, and requires one Accusensor III sensor for solid-state
enthalpy sensing. A second Accusensor III sensor (required for all units
for differential enthalpy sensing) compares outdoor temperature and humidity to return-air temperature and humidity and determines the most
economical mixture of air (purchased in addition to enthalpy control
[sizes 036-150] or to first solid-state enthalpy sensor [sizes 180-300] for
differential enthalpy sensing).
POWER EXHAUST (180-300 SHOWN)
When used with accessory/optional economizer, the power exhaust
accessory helps to relieve building over-pressurization.
