Actuator KNX S1R-B4 compact
• Version: 12.09.2022 • from application 1.0 • Technical changes and errors excepted.
5.2.1.4.Automatic - internal for shading (drives)
The menu item "Automatic internal" appears if internal automatic is selected for
"control". The internal automatic functions take into account the brightness/position of
the sun, outdoor and indoor temperature and allow a time and dimming control. A
shading position can be specified or taught.
To be able to fully utilize the internal shading automatic, information about brightness/
twilight, outdoor and indoor temperature, time and position of the sun must be present
in the bus system.
Outdoor temperature block:
The input object "outdoor temperature block" is linked with the output object of a
temperature sensor. The input object can be a 1bit object (smaller or larger than a
threshold value), as well as a 16bit object (measurement value).
1 bit input object:
Shading is allowed if the bit is 0 and blocked if the bit is 1.
16 bit input object:
Shading is allowed
if the measurement value is larger than the threshold value+hysteresis
and blocked
if the measurement value is smaller than or equal to the threshold value.
Twilight/time control:
The time control is provided via a communication object. The input object "twilight
control" is linked with the output object of a brightness sensor. A 1bit object (smaller
or larger than a threshold value), as well as a 16bit object (measurement value) can be
used for the twilight control.
