TIP
If you wish to set similar scheduling for every day of the week start by filling
in "all" and then changing the desired days.
Caution
If the stop time is before the start time it means that the period extends past
midnight.
Scheduling always starts on the date that the start time is set for.
Caution
Long term blocking can cause reduced comfort and operating economy.
