How to use

Install the module into an AS/A F50 series frame according to the manufacturer’s mounting instructions and connect it to the KNX bus. Use ETS (Engineering Tool Software) or compatible KNX configuration software to address the device, assign group addresses and configure each of the three touch channels for required functions such as switching, dimming, scene recall or shutter control. After programming, verify functionality by testing each touch input and observing the corresponding KNX group object responses.

Recommendations

Place the module at comfortable reach height for users and protect it from direct water exposure. Program tactile feedback and time delays in the KNX project where appropriate to avoid unintended actions. For reliable operation, follow KNX topology and wiring guidelines and perform a system backup after configuration changes.
