Numerical Constant Controls
Whether
the box is assigned any of the remaining “constant” control options, the central
button in the box will react to user presses by sending a certain numerical value, which
is required to be specified under
Constant value
. This numerical value will depend on
the constant control type selected to the box (
Function).

Table 2 shows, for every available Function, the permitted value range and the name of
the object through which the values are sent to the bus.

2-BUTTON CONTROL
Boxes configured as 2-button controls consist in an indicator and two buttons that, when
touched, trigger the sending of an action to the KNX bus through a certain object.
As a general rule, most of the 2-button controls permit configuring a pair of parameters,
Left button
and
Right button
, each containing a dropdown list for the selection of the
icons to be displayed inside the buttons in the box.
Note:
When multiple presses are made consecutively on the buttons of a control that
regulates (e.g. increases / decreases) the value of a certain variable, only the final value
