22.7 Operating strategy for light
Desigo room automation has various room operating modes available to
efficiently control lighting. The system can, depending on the selected room
operating mode, reduce light output in the rooms through the use of automatic
light functions. This generally occurs during periods of absence, at night, during
holidays, when spaces are not occupied.
Four different room operating modes are available that can execute control, via
central functions, management stations, schedulers, presence buttons in the
room or other BACnet participants in the system.
With Desigo room automation, the operating modes "Economy" and
"Protection" can determine how much light output is automatically reduced. In
operating modes, "Comfort" and "Pre-Comfort", lighting control is conversely
not reduced using automatic light functions, so that lighting can be controlled
to the maximum.
