Planning an automatic sun protection system that tracks the sun's position
The following KNX components are required for setting up an automatic sun protection system that tracks
the sun's position:
•
Blind/Roller Shutter Actuator with Binary Inputs
•
KNX switch sensors or universal interface with push button or direct via the binary inputs of the
blind/shutter actuator brightness sensor
•
Blind Control Unit
The current position of the sun is calculated based on the time of day. The Blind Control Unit can be
operated as an independent clock, a master clock or a slave clock on the KNX. Several Shutter Control
Units can also be synchronized together. If the Shutter Control Unit is operated as an independent or
master clock, no further time switches are required.
The Shutter Control Unit can likewise be operated as a slave clock, if for example there is a master clock
in the installation. A time switch which can send the time and date on the KNX must be used as a master
clock.
4.1.3.2
Status feedback
Position in [0...100]
The Blind/Roller Shutter Actuator can feedback the position of the blind on the bus as an 8-bit value via the
same group object used to call the position. The corresponding group address should be defined in ETS
as the "sending group address".
