9. Restore Power: Turn on the circuit breaker, then turn on the main power switch for the furnace.
10. Test Operation: Initiate a heating cycle to ensure the furnace operates correctly. Observe for any error codes or unusual behavior.

6. Operation

The control board operates automatically, managing the furnace's heating cycles, fan operation, and safety features based on signals from the thermostat and internal sensors. Once properly installed, no direct user interaction with the control board is typically required for normal operation.

Refer to your furnace's specific user manual for details on setting thermostat temperatures and understanding furnace operational modes.
