This application control local operation of shading in the room. It is optimized for short response times between pushing the button and the response by the lighting actuator.

The room occupancy has the following commands are available to manually operate shading:

  • Up
  • Down
  • Stop and step up
  • Stop and step down

Manual operation overrides automatic

Manual operation by the user can override any existing automation in the room. Any manual operation must be released to return to automatic mode.

DXR2 applications have the following methods to this end:

  • A central scheduler program
  • Presence detector detecting non-occupancy
  • Central commands from the management platform
  • By manual operation (first-time switch on or appropriately configured button)

LED indicators on buttons

The LED feedback to the KNX PL-Link pushbutton pairs can be used to provide the room user with feedback as to whether manual operation for shading is enabled or locked. The LED feedback can also be disabled in another operating mode. LED feedback is then switched off.

Protection functions

Safety of persons

Blinds are opened during a fire to allow people to exit through a window or help emergency responders access the facility.

Collision protection

Collision protection prevents blinds from closing if a window or door is opened to the outside.

Wind protection

The protection function ensures that all blinds are commanded to a safe position during strong winds.

Maintenance work

The blinds are commanded to a defined position and blocked so that no person is endangered.

Delays central commands

Delays to blinds start up are automatically considered when commanding all blinds on a facade by a central function to prevent the start-up current for blinds motors from negatively impacting or even overloading the building.

Monitoring blinds actuators for faults

The function monitors communications with the blinds actuators of the Desigo room automation. The management platform sends a fault message if communication fails between the Desigo room automation station and blinds actuators. So that appropriate measures can be taken.

See central functions for additional information on protection functions.

Central functions

Central functions for anti-glare protection, solar position tracking of slats, annual shading and energy efficiency functions for blinds are included in the automatic functions.

See description of central functions for additional information on automatic functions.
