Application "2-button blind"

Application "2-button blind"
NOTE
The application is valid for the following parts of the device:
■
Button 1 / rocker 1
■
Button 3 / rocker 2
Via the application "2-button blind", blind movement and/or slats adjustment commands can be
sent to connected blind actuators with a short or long actuation of the button. A short button
press always triggers a travel command and a long button press always triggers a slats
adjustment or stop command. In each case, the "2-button blind" application makes a separate
set of parameters and communication objects available for the right or left side of the button.
This thus facilitates controlling a blind using one side of the button and assigning a "button
orientated" function to the other side of the button. The control always remembers the last
action performed on the side of the button that is assigned with the "2-button blind" application.
For example: If a blind was lowered and halted at half height via a long press of the button, then
a renewed short press of the button will raise the blind.
10.15.1 General parameters - Time for long operation
Options:
00.300 ... 03,000
A differentiation can be made between a short or long operation of the button. With a short
operation of the button, the next level forward is switched to in each case. With a long
operation, the first level is activated. Thus with a long button press a jump back from every
position to the first level is possible, without having to run through the remaining levels.
Via the "Duration of long operation", the time is specified from which a long button press is
recognised and the object values are reset. The first level must be set again with a press of the
button. Any time from 0.3 to 3 seconds can be set. A typical value after which a jump-back to
level 1 is made is 0.4 s.
10.15.2 General parameters - Object type
Options:
1 bit
1 byte 0 - 100%
Via the parameter object type, you can specify whether the blind control occurs via two 1-bit or
two 1-byte communication objects "Move" and "Adjust".
If 1-byte was selected as object type, the communication objects can be connected with 1-byte
position objects from blind actuators. For example: One side of the button could lower the blind
to 50% with slats closed 50%, while the other button side can lower the blind to 80% with slats
closed 100%.
