This schedule determines the overall period of time
for which the entire building is in use. Typically, it is
used for night setback throughout the building or for
S
long periods when the building is not in use.
When the building is not used, interventions of third
priority are disabled. This prevents demand signals
S
from being sent to the primary plant when e.g. a
security guard enters a room.
