Building Technologies Room operating modes 2013-06-17
The state of the room controller (result of the logic OR operation) is mapped to the
building automation and control system via the following S-mode communication

Master/slave applications
Bindings are required in S-mode, in order to transmit the slave window contact status to
the master.

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
the building, or for longer periods when the building
is not in use.
Outside the “building-in-use” times, inputs from
3
rd
priority sources are disabled. This prevents
demand signals from being sent to the primary plant
when, for example, a security guard enters a room.
The table below shows the three possible occupancy states and the resulting effective
room operating mode.
Switch state Description Effective room op. mode
Building in use • 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)
As defined by Occupancy
time schedule, presence
detector or room unit
Building not in use • 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
Economy
Building protection • 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
