Safety first: Ensure the generator is in AUTO and that no active alarms are present before adjusting settings.

Steps:

Check clock: Set the correct date and time on the Honeywell controller.
Verify exercise settings: Confirm that the exercise function is enabled and scheduled for the desired day and time.
Battery status: Ensure the battery is healthy and that no Low Battery alarm is present.
Manual test: Run a manual test to confirm the unit can start and run. If manual works but exercise does not, the controller may need firmware update or replacement.
