Art. No. SC 1000 KNX
4.2.4.1.2 Operation concept and sensor evaluation
Direct operation / Selection operation
The operation concept for elements on the touch surface is distinguished between selection
operation and direct operation. The selection operation is normally intended for the room or
function view. Functions, i.e. controllable KNX channels, must first be selected. Afterwards,
operations are performed by means of the control command (switch on or off, move up or
down, ...). Alternatively, direct operation for the start and favourite display page is available. In
this case, the control command is also executed simultaneously time by touching the operating
element. This operation concept is the same as the operation of a push-button sensor. It can be
used in particular on the start page for purposefully executing central functions quickly and
clearly (e.g. "All ON / All OFF", "room lighting ON / OFF").
In the ETS you can configure which operation concept is used on the start and favourite page.
Operating elements on the touch surface can - depending on the underlying function - be
evaluated as a rocker switch (double-surface principle) or as a button (single surface principle)
(see page 78). The function as rocker or button does not depend on the configured operation
concept and can therefore be used individually for a selection operation as well as for a direct
operation.
For a direct operation, the display surface of an element also corresponds to the sensor surface
at the same time, i.e. the function operational area (figure 22). The underlying function is
executed immediately by touching the sensor surface with your finger (1.).
This is different in the case of a selection operation. In this case, an operating area is also
displayed in the device display next to the display surface of the element. The display of the
selection operation depends on the page on which the operation is executed. On the start or
favourite page all controllable functions are displayed one above the other (figure 23). Operation
requires the selection of an element (1) that can then be operated (2.). The unselected
elements on the page remain visible in the display but are greyed out and can therefore not be
linked to the control surface. It is possible to change the controllable function at any time by
touching another display element with your finger.
In the room or function control only one controllable function is ever visible in the display for the
selection operation. You must select beforehand in the relevant submenu which KNX channel of
a room or function unit is operated. If a channel only contains one controllable function (e.g.
switching ON/OFF or rolling shutter height), an activation can take place immediately in the
operating area. If a channel contains two operating functions (e.g. Venetian blind with blind/
shutter height and slat position), the controllable function must first be selected in the display
area (1.) and then activated in the operating area (2.) (figure 24).
