Description
Use input?
The input controls a blind
actuator.
I1 is used purely as a KNX binary
input.
There is no internal connection to
the switch actuator.
In order to avoid disruptive
switching due to bouncing of the
contact connected to the input,
the new status of the input is
only accepted after a delay time.
Larger values (≥ 1 s) can be used
as a switch-on delay.
No block function.
Show block function parameter
page.
0 = cancel block
1 = block
0 = block
1 = cancel block
Serves to clearly differentiate
between long and short button
push.
If the button is pressed for at
least as long as the set time,
then a long button push will be
registered.
No double-click function
The double-click parameter page
is shown.
Serves to differentiate between a
double-click and 2 single clicks.
Time period in which the second
click must begin, in order to
recognise a double-click.
