6.2.6. One-button shutter
A long button press affects the communication object "Sun protection up/down" which
is responsible for starting the up down movement of the shutter or blind. Movement
direction is toggled by every button press. The one-button shutter is a start movement
function meaning a move up or move down command is sent on activation. A short
button press affects the switching object "Blinds open/close" for stopping the
movement and/or adjusting the blinds.
6.3. Channels A/B, C/D
Combined input channels have one two-button function. Configuring the two-button
functions "Dimming" and "Shutter" is only possible by use of combined channels.
According to the setting in the "General" tab either two-button dimming or two-button
shutter can be configured for a combined input. In contrast to the one-button functions,
assignment of buttons can be made individually. For example, it is possible to
configure one button will drive shutters up and the other one will drive them down.
