KNX RF radio actuators in compact design

KNX RF radio actuators in compact design News of 09.05.2019

The new actuators KNX RF S1R-B2 compact and KNX RF R1-B2 compact 16A are the ideal solution if no KNX cable is to be laid and the installation space is limited. The compact devices are easily concealed in a standard flush-mounted box. The actuators use the certified radio standard KNX RF and, as S-Mode devices, are configured directly via the ETS.

Benefit from the advantages of radio also in KNX systems:

  • Low installation Costs
  • Easy retrofitting
  • No intervention in the building structure, perfect for monument protection requirements

The radio actuator KNX RF S1R-B2 compact is multifunctional and switches up to 5 A.

It can be used for one drive (blind, awning, roller shutter, window) - or for two electrical devices (e.g. light or ventilation). The two devices are switched separately. Blocks can be activated and priorities set in the KNX application, e.g. for manual operation or protective functions. Individual scenes can be created in 16 memory modules.
Two digital inputs are available for connecting push-buttons or other auxiliary contacts.


KNX RF R1-B2 compact 16 A switches a consumer up to 16 Ampere at a potential-free relay output.

Not only fans or heating can be controlled via KNX, the actuator is also particularly suitable for switching light.
A on/off delay or a staircase lighting function with switch-off warning can be set. Switch-off warning here means that the light goes out briefly a few times before it is switched off. This "flashing" can be precisely defined in the KNX application.

In the online shop you will find further technical information about KNX RF S1R-B2 compact and KNX RF R1-B2 compact 16A, for example data sheet, manual and KNX application.
There you will also find further actuators for the KNX System.
