Set the stop time earlier than the start time so that the period extends
beyond midnight. Scheduling then stops at the set stop time the day
after.
Scheduling always starts on the date that the start time is set for.
Caution
A significant change over a longer period of time may cause poor indoor
environment and worse operating economy.
