Application "1-button light scene extension unit with memory function"
NOTE
The application is valid for the following parts of the device:
■
Button 1 / rocker 1
■
Button 2
■
Button 3 / rocker 2
■
Button 4
When a button is actuated a predefined light scene number is called up. In each case, the
application makes a separate set of parameters and communication objects available for the 1st
and the 2nd button. The application makes it possible to call up a light scene via one button side
while the other button side can be assigned with a further "button-oriented" function. The user
has the option to trigger a light scene memory command via a long actuation of the button.
10.11.1 General parameters - Time for long operation
Options:
00.300 ... 10.000
A short and long operation can be differentiated between for the operation of the button. For a
short operation of the button, a preset light scene is called up on the 1-byte communication
object "Light scene number". For a long operation, a command for storage of the preset light
scene is sent out on the same communication object.
Via the "Duration of long operation", the time is specified after which a long button press is
recognised and a command for the light scene storage is sent out instead of the light scene
number. Any time from 0.3 to 10.0 seconds can be set. A typical value, after which a button
triggers a storage for a long press is 3 s.
10.11.2 General parameters - Light scene memory function
Options:
Deactivated
Activated
Within the 1-byte value, a memory bit is set in addition to the light scene number. If a light scene
module (e.g. Busch-ComfortTouch®) receives this 1-byte value, the module can identify the
affected light scene and trigger a storage procedure. Read requests are sent to all connected
actuators that in turn answer with their current communication object values. The answers are
saved by the light scene module and are sent out again for every future receipt of the light
scene number.
