KNX Blind Control Extension
Description
The BX8 KNX DIN rail mounting module for Blind Control Extension takes over the automation of the sun protection in the KNX bus system. The device offers extensive customisation options for the building situation and shading type, e.g. facade alignment and slat width. Up to eight facades can be controlled according to brightness and the position of the sun. Both the slats and the shadow edge can be adjusted according to the position of the sun. Rain, wind and temperature (inside/outside) can also be taken into account and global radiation values integrated.
- Event-driven, calendar-based and weekly timer functions round off the automation.
- The corresponding weather, time and location data must be available on the bus system, e.g. via a weather station.
- Both push-buttons for switching or for controlling drives, as well as encoders and scenes, can be integrated into the KNX system via nine digital inputs.
