Description of application and parameters
application - "2-button value dimming sensor"
KNX Technical Reference Manual 1473-1-8905 / 2CKA001473B8905

application - "2-button value dimming sensor"
NOTE
The application is valid for the following parts of the device:
■
Button 1 / rocker 1
■
Button 3 / rocker 2
With the "2-button value dimming sensor" application it is possible to send 1-byte value
telegrams via an operation of the rocker.
Each operation of the left or right side of the rocker will increase or reduce a 1-byte value
(percent or value from 0 to 255). The 1-byte value can be connected with 1-byte brightness
value objects of dimming actuators. This allows a dimming actuator to be dimmed brighter or
darker with the rocker via value telegrams.
10.17.1 General parameters - Object type
Options:
1 byte 0 - 100%
1 byte (0 - 255)
The 1-byte communication object "Value" is set via the "Object type" parameter. With the setting
"1 byte 0..100%", the momentary value is increased or reduced by a percentage amount for
every operation. With the setting "1 byte 0..255", the momentary value is increased or reduced
by an absolute value for every operation.
How large the percentage value or the absolute value will be is specified via the "Step size"
parameter.
10.17.2 General parameters - Step size
NOTE
The options are dependent on the setting of the "Object type" parameter.
Options:
1 … 50 %
1 … 128
1 byte 0 - 100%
: The size by which the momentary value is to be increased or reduced for an
operation is set via the "Step size" parameter. A percentage value can be specified.
Example: The current value on the 1-byte communication object "Value" amounts to 40%. For a
step size of "10%", the current value is increased from 40% to 50% for an operation (for an
increase).
1 byte 0 - 255:
The size by which the momentary value is to be increased or reduced for an
operation is set via the "Step size" parameter. An absolute value from 1 to 128 can be specified.
Example: The current value on the 1-byte communication object "Value" amounts to 100. For a
step size of "20", the current value is increased from 100 to 120 for an operation (for an
increase).
