Keyboard for entering values
In addition to the possibilities of specifying a brightness value using the sensor surfaces
+
/

or
slider, a keyboard can optionally be shown in the display. It is possible to specify a brightness
value directly using the keyboard. The keyboard becomes visible by pressing the display area
for a long time with your finger (approx. 1s) if this was enabled by parameter configuration in the
ETS. Using the keyboard, any brightness value ranging from 0...100% can be entered
numerically and applied by pressing the
>
button. After applying the value, it is accepted as a
preset value and transmitted to the bus.
The entry can be terminated without applying any value by touching the sensor surface

in the
keyboard.

It is only possible to specify a brightness value via the keyboard in selection operation on
the room or function pages.
Objects
A channel of the function "dimming (brightness value)" has 2 KNX communication objects...
-
"D.Output channel x - Dimming (brightness value)" (1-byte transmitting):
Value telegrams (0...255) are transmitted to the bus via this object after pressing the
sensor elements. This can cause a dimmer actuator to be activated.
-
"D.Input channel x Dimming (Feedb. brightness value)" (1-byte receiving):
Through this object the device can receive a brightness value feedback that a dimmer
actuator transmits, for example. The status value, status icon and bar graph 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 brightness value must be transmitted by the "actively transmitting"
actuator.
If the activated KNX dimmer actuator does not have a separate brightness value feedback,
the object "D.Input channel x - dimming (Feedb. brightness value)" can be linked to the
object "D.output channel x - dimming (brightness value)" via an identical group address.
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 %.
i
During an operation, the value of the object "D.Input channel x Dimming (Feedb. brightness
value)" is not evaluated. With a long press of the sensor elements
+
/
-
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
dimmer actuator after the operation has been completed.
