JUNG KNX RF Wireless Wall Transmitter Module, 4-Gang, F40 (4074 RF TSM)

For KNX installations where a wired bus connection is impractical or impossible, this radio touch sensor module adapter frame provides a wireless control solution. It enables four independent functions to be controlled via KNX RF, allowing switching, dimming, blind control, value transmission, and scene recall without additional wiring.

Who is it for

This module is intended for electricians, system integrators, and advanced users who are building or extending KNX smart home or building automation systems. It is particularly suitable for retrofits where adding new cables would be disruptive, or for installations in listed buildings where preserving the fabric is essential.

Tips

When planning your installation, ensure that the chosen rocker and frame are from a compatible Gira range. The module itself does not include these components, so they must be ordered separately. For optimal radio performance, avoid mounting the module inside metal enclosures or near large metal objects that could attenuate the signal.
