1) The 1-way push button (single push button) changes the direction of travel after a long click.
2) Depending on the installation of the digitalSTROM relay terminal block the direction of travel for the 2-way push button only matches the open/close button after calibration. Check the functionality of the push button while approaching the first end position and use the other open/close push button as necessary. For each additional step use the other applicable push button (symbolised by ?). After calibration the push buttons will match the effective direction of travel.
