KNX wall switch MDT BE-TAL55T106.A1 Taster Light 55 1‑gang RGBW with temperature sensor, matte black

MDT BE-TAL55T106.A1 is a KNX wall switch from the Taster Light 55 series, featuring a single push-button (1‑gang) with RGBW lighting control and an integrated temperature sensor. The switch is designed for KNX home and building automation and fits standard 55 mm frame systems. Its matte black finish provides a neutral appearance suitable for modern interiors while the device offers control options for lighting, blinds and scenes as well as temperature feedback for HVAC or comfort automation tasks.

Advantages

The MDT KNX 1‑gang switch combines tactile push-button control with RGBW channel output and a built-in temperature sensor, enabling both manual interaction and automated responses in KNX installations. Compatibility with 55 mm frame systems and a slim profile allow easy integration into existing electrical frames. The matte black surface resists visible fingerprints and matches common interior design schemes. The device supports scene and blind control in addition to lighting, reducing the need for multiple wall units.

Suitable for

• KNX home automation panels and room control installations
• RGBW lighting control in living rooms, bedrooms or hospitality spaces
• Integration with HVAC or building management via temperature feedback
• Scene control and blind/shade actuation in residential or commercial projects

Key specifications

• Form factor: 1‑gang push-button (Taster) for 55 mm frame systems
• Lighting control: RGBW channel output for colour and white control
• Sensor: integrated ambient temperature sensor for room measurement
• Mounting: wall-mounted, compatible with standard 55 mm module frames
• Finish: matte black surface
• Control functions: push-button for lights, blinds and scenes via KNX bus

How to use

Install the MDT BE-TAL55T106.A1 into a compatible 55 mm frame and connect it to the KNX bus according to the project's wiring plan and KNX installation rules. Configure the device parameters and group addresses in the ETS software to map the push-button to lighting outputs, RGBW channels, blind actuators and temperature datapoints. Use short and long presses or configurable multi-press actions to operate lights, trigger scenes or control blinds. The integrated temperature sensor reports ambient temperature to the KNX system for HVAC or automation logic.

Usage recommendations

Place the switch at standard ergonomic height for wall controls and avoid direct exposure of the temperature sensor to radiators, direct sunlight or ventilation outlets to ensure accurate room temperature readings. During commissioning, verify RGBW channel mappings and fine-tune temperature calibration in ETS if required.
