FEATURES/BENEFITS

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.
