The table below shows the three possible occupancy states and the resulting e ffective
room operating mode.
Description
• Full availability of all plant
• Building enabled for use
• Inputs of priority 3 are enabled ( Occupancy time
schedule, presence detector, room unit, and
Temporary Comfort mode)
• Reduced availability of plant
• Inputs of priority 3 are disabled ( Occupancy time
schedule, presence detector, room unit, and
Temporary Comfort mode)
• Application:
Building temporarily not in use
The building must reach the Comfort
temperature within hours
• Setpoints reduced to the minimum necessary to
protect the building fabric.
• Inputs of priority 3 are disabled ( Occupancy time
schedule, presence detector, room unit, and
Temporary Comfort mode)
• Application:
Longer periods of non-use of the building

This time schedule determines the overall period of
time for which the entire building is in use. Typically,
this schedule is used for night setback throughout
S
the building, or for longer periods when the building
is not in use.
Outside the "building-in-use" times, inputs from
S
rd
3 priority sources are disabled. This prevents
demand signals from being sent to the primary plant
when, for example, a security guard enters a room.
