When you have a schedule selected, if you make manual changes to the temperature setpoints, you'll see a message about the schedule being in Hold since you have manually overwritten the schedule setpoint(s). You can customize the duration of the Hold, but by default the schedule is on hold until the next period. After a Hold is set, you can choose to Cancel the schedule hold, which will resume the schedule to normal operation.
