Design of an automatic sun protection system with tracking of the
sun’s position
To set up an automatic sun protection system with tracking of the sun’s
position, an additional Shutter Control Unit JSB/S 1.1 is required.
The current position of the sun is continually calculated in the shutter control
unit. The shutter is moved via an 8 bit value into the optimum position to
deflect direct sunshine but to let through as much diffuse light as possible.
The influence of shadows e.g. the buildings opposite can also be taken into
account in the shutter control unit.
Planning a simple automatic sun protection system with tracking of the
sun’s position
The following KNX components are required for setting up an automatic sun
protection system (including automatic sun protection with tracking of the
sun’s position:
•
Room
Master
•
KNX switch sensor or universal interface with push button,
or direct via the binary input of the Room Master
•
Brightness
sensor
•
Shutter control unit
