Actuator for KNX Radio for 2 Drives

The KNX RF-MSG2-DST is a radio actuator for KNX radio (KNX RF). The actuator controls two drives separately (blind, shutter, awning or window). The KNX RF MSG2-DST uses the KNX RF S standard.

  • 2 connections for 230 V drives (STAK3), separate control
  • Reception of the control signal via radio KNX RF
  • Retransmitter function (from version 1.1): Forwarding of all received KNX RF telegrams. These can be received by KNX RF participants with the same domain address. This allows the range of the KNX RF signal to be increased
  • Automatic runtime measurement of the drives for positioning (incl. fault reporting object)
  • Position feedback (movement position, also slat position for shutters)
  • Position storage (movement position) via 1-bit object (storage and call-up e.g. via buttons)
  • Scene control for movement position with 16 scenes per drive (also slat position for shutters)
  • Blocking objects and alarm reports have different priorities, so safety functions always take precedence (e.g. wind block)
  • Manual or automatic priority setting via time or communication object
  • Brief time limit (movement command blocked) and 2 movement limits
  • Configuration is made using the KNX software ETS 5
