"D.Input channel x Venetian blind feedb. blind/shutter height" (1-byte receiving):
Through this object the device can receive a position feedback for the blind/shutter height
that a shutter actuator transmits, for example. The status value, status icon and bar graph
for the blind/shutter height visualisation are influenced as a result. Consequently, the
feedback object must always be configured properly so that the status indications of the
channel element work correctly.
The feedback of the position value must be transmitted by the "actively transmitting"
actuator.
-
"D.Input channel x Venetian blind feedb. Slat pos." (1-byte receiving):
Through this object the device can receive a position feedback for the slat position that a
Venetian blind actuator transmits, for example. The status value, status icon and bar graph
for the slat visualisation are influenced as a result. Consequently, the feedback object must
always be configured properly so that the status indications of the channel element work
correctly.
The feedback of the position value must also be transmitted here by the "actively
transmitting" actuator.
i
The objects interpret values to be sent or received on the basis of the KNX data point type
5.001 (Scaling). The decimal data values 0...255 are evaluated as percentages 0...100 %.

or when moving the slider, a
continuous value adjustment can take place on the bus. During this value adjustment, all
status elements of the channel element are updated continuously by value simulation. The
display elements first react again to the feedback object value of the Venetian blind or
shutter actuator after the operation has been completed.
Slat correction
A KNX channel of the function "Venetian blind/shutter (position)" supports the supplementary
function of the slat correction. Many KNX shutter actuators track the slat position when the
shutter height changes due to a position setting. These actuators also reposition the slats when
the blind position is preset to 0%, i.e. to the upper end position. This repositioning of the slats is
often undesirable in the upper end position of the blind since the returned blind height also
changes again due to the movement of the slats (position of blind unequal 0%). To prevent the
slat from being repositioned in the upper blind end position, the automatic slat correction can be
activated in a KNX channel "Venetian blind/shutter (position)". It can be activated by parameter
in the ETS.
If the slat correction has been activated, the device always transmits a slat position of 0% for a
blind height presetting of 0%. As a result, the slat is not repositioned when the upper end
position is reached since this is already in the 0% position after the upward movement. It does
not matter which operation performs the 0% presetting. Consequently, the slat correction will
only function after short or long operations of the sensor surfaces or when changing the slider if
a 0% blind position is set.
The automatic slat correction does not apply to position presettings for the blind within the range
1...100%. In such cases, the device only transmits slat positions when a slat operation is
performed using the sensor surfaces or the slider.
i
The slat correction is available only in the "Venetian" blind' shading method.
