5.4.3 E 1...E2 blind up/down
4 3 B
Two buttons are connected to actuate a blind (E1 + E2).
Objects 9 (step/stop) and 10 (up/down) are linked in this case using a KNX blind
actuator.
With both inputs, a distinction is made between a short press and a long press of the
button. The time to distinguish between long and short button presses is set on the
Input E1 parameter page.
With a short press, the relevant program (ON or OFF) is sent to the slat object (obj.
9), with a long press a telegram is sent to the motion object (obj.12).
Only one or the other object is ever pressed at a time.
If a button is held down, the other is ineffective.

*The decision between step and stop is carried out in the blind actuator itself,
depending on the operating position.

press.
