GAS HEAT MODELS — All ignition components are contained
in the compact IGC (integrated gas controller) which is easily
accessible for servicing. The IGC control board, designed and
manufactured exclusively for Bryant rooftop units, provides
meets
built-in diagnostic capability. An LED (light-emitting diode) sim-
plifies 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 error code is issued. This feature greatly improves reli-
ability 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 mini-
mizes service costs. The IGC also maximizes heating effi-
ciency by controlling evaporator-fan on and off delays.
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 heat-
ing efficiency.

Summary of Contents for Bryant 581A/B

  • Page 1 GAS HEAT MODELS — All ignition components are contained in the compact IGC (integrated gas controller) which is easily accessible for servicing. The IGC control board, designed and manufactured exclusively for Bryant rooftop units, provides drain pan, meets built-in diagnostic capability.

  • Page 2: Table Of Contents

    IGC board locks out the gas heat cycle to prevent any fur- ther 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.

  • Page 3: Features/Benefits

    Bryant-specified hermetic compres- sors are equipped with compressor overcurrent and overtem- perature protection to ensure dependability. All units have Bryant’s exclusive Acutrol™ (036-150) or TXV (thermostatic expansion valve) metering device (155-300) which precisely controls refrigerant flow, preventing slugging and flood-back, while maintaining optimum unit performance.
  • Page 4 EXCLUSIVE HOT GAS REHEAT DEHUMIDIFICATION PACK- AGE (581A181-300) — The hot gas reheat dehumidification package is a result of recent advances by Bryant in controlling comfort levels. This factory-installed option significantly improves the dehumidification capability of the rooftop unit and helps control humidity levels in the building.

    OPERATING SEQUENCE, SIZE 036-151 UNITS Cooling, Units Without Economizer — When thermostat calls for cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC) and compressor contactor are energized and indoor-fan motor, compressor, and outdoor fan starts. The outdoor-fan motor 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 contac- tor no.
  • Page 260 Heating, Units Without Economizer — 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.
  • Page 261 When the thermostat is satisfied and W1 and W2 are deener- gized, the IFM continues to run and the economizer damper then moves to the minimum position. Units With Hot Gas Bypass Dehumidification Package — When thermostat calls for cooling, terminals G and Y1 and Y2 and the compressor contactors C1 and C2 are energized.

    If field-installed accessory CO sensors are connected to the EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO level in the zone increases above the CO set point, the minimum position of the damper will be increased proportionally.

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 previ- ous postcoating processes.
