Art. No. SC 1000 KNX
4.2.4.1.10 Channel function "2-byte value transmitter"
With the channel function "2-byte value transmitter", telegrams in compliance with the KNX data
types 9.0xx (floating-point numbers) can be transmitted to the bus. The activation of other bus
devices enables the user, for example, to specify temperature or brightness values or to
generate any preset values for other physical sizes with negative or positive signs.
A KNX channel "2-byte value transmitter" has a display element and sensor surface in the
graphic interface for operation. The display area and sensor area, depending on the existing
operation concept, are combined into one surface (direct operation) or distributed on two
surfaces (selection operation). The sensor element is always executed as a push-button
function and does not distinguish between any short and long operations.
A sensor operation triggers the value telegram configured in the ETS. In addition to recalling
values by operation of the sensor surface, it is possible to use a keyboard for presetting the
value (see page 106-107). As a result, it is possible optionally to permanently change the value
that was originally preset in the ETS and thus to adapt it at any time.

The value transmitted via the communication object of the channel can vary from the preset
value during a sensor surface operation (ETS or keyboard specification) because a gain
factor and value offset can be configured optionally (see "Objects" below).

With the function "2-byte value transmitter", it is possible to switch off the operating function
completely in the ETS. In this case, the channel concerned only works as a display function for
value visualization. Consequently, touching the sensor or display elements does not induce any
response.
