The current position of the sun is calculated based on the time of day.
The Shutter Control Unit can be operated as an independent clock, as a
master clock or as a slave clock on the KNX. Several shutter control units
can also be synchronised together. If the Shutter Control Unit is operated
as an independent clock or as a master clock, no further time switches are
required.
The Shutter Control Unit can likewise be operated as a slave clock if for
example a master clock is present in the installation. A time switch which can
send the time and date on the KNX must be used as a master clock.

Status feedback
Position in [0…100]
The Room Master can feedback the position of the shutter on the bus as an
8 bit value via the same communication object used to call the position.
The corresponding group address should be defined in the ETS as the
“sending group address”.
