  • Pressing the button in the same direction while the cover is moving: Stops the cover.
  • Pressing the button for the opposite direction while the cover is moving: Reverses the cover movement until the endpoint is reached.

Switch input configuration:

  • Turning the switch on: Moves the cover in the corresponding direction until the endpoint is reached. Turning the switch off: Stops the cover movement. Both switches turned on: The Device respects the last engaged switch. Turning off the last engaged switch stops the cover movement, even if the other switch is still on. To move the cover in the opposite direction, turn the other switch off and on again.
  • In Dual input mode, the Device supports Slat control that allows for precise adjustment of slats in Venetian blinds.

This function has the following settings:

  • Open time – the duration in seconds for the slats to transition from fully open to fully closed position.
  • Close time – the duration in seconds for the slats to transition from fully closed to fully opened position:
  • Default: 1.5 seconds
  • Accepted range: 0.5-10 seconds

Step – controls the incremental movement of the slats in percent between the two endpoints:

  • Fully closed position (0%)
  • Fully opened position (100%)

Button input configuration:

  • Pressing a button when the cover is static: Moves the slats in the corresponding direction by the predefined step.
  • Pressing the button in the same direction while the cover is moving: Stops the cover.
  • Pressing the button for the opposite direction while the cover is moving: Reverses the cover movement until the endpoint is reached.
  • Pressing and holding the button moves the slats and the cover in the corresponding direction until the endpoint is reached.

Switch input configuration:

  • Turning the switch on: Moves the slats and the cover in the corresponding direction until the endpoint is reached.
  • Turning the switch off: Stops the cover movement. Both switches turned on: The Device respects the last engaged switch. Turning off the last engaged switch stops the cover movement, even if the other switch is still on. To move the cover in the opposite direction, turn the other switch off and on again.

In Detached mode, the Device can only be controlled through its web interface and its app. Buttons or switches connected to the Device will not control the motor rotation,
