schedule sets the typical On/Off times for the unit. The holiday schedule can be
programmed for up to 12 separate On/Off events with any combination of days.
The holiday schedule sets the Off times for holidays and other shutdown periods.

except during the weeks of Thanksgiving and Christmas when the units will be
Off. However they will run each weekday during the Thanksgiving shutdown
from 8:00 AM until noon while a maintenance crew is in the building. AdaptAire
