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.
