My AeraForHome app won't let me set a schedule.

From the home screen, open the programed schedules by clicking the calendar icon on the top right corner. Above the schedules, click the edit icon and delete competing schedules.

NOTE: You cannot create a schedule that extends across 2 days such as one that crosses past midnight to the next day. You would need 2 schedules. For example, a schedule for 8PM to 3AM would be set as 2 schedules: 8:00PM to 11:59PM and 12:00AM to 3:00AM.
