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 di-
ode) simplifies troubleshooting by providing visual fault notifica-
tion 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 reliability
of the rooftop unit.

    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), com- pressor no. 1 (580D036-150 and 579F216-300) or unloaded compressor (579F180), and condenser fan(s) start.
  • Page 64 Cooling, Units With Parablade Economizer (580D036-072) — When the outdoor air is above the enthalpy control (EC) set- ting, and the room thermostat calls for cooling, and the com- pressor contactor is energized to start the compressor and the condenser-fan motor. The evaporator-fan motor is energized and the economizer damper moves to the minimum position.
