Function A/B:
[1 to 64]
[Dim] or [Dim and switch]
This operating mode serves to address KNX dimmers. When receiving the keycode A
or C, the command dim up is sent to the bus, when receiving the keycode B or D, the
command dim down.
By setting the parameter [dim and switch], a short-time object for switch commands for
channel A/B is created in addition to the dim object. The switch command for the key-
codes A/B is then triggered when the button is pushed <1.6 seconds. If the button is
pressed longer, the dim function is used.
Attention!
If the execution of this function should lead to interference on the radio line,
the secure distinction between long-time and short-time objects cannot be guaranteed.
In case of an error, a switch command would be sent instead of a dim command. This
leads to the complete ON/OFF of the KNX actor, independent of the current dim stage.
This option is not available for dimming with the buttons C/D.
