gira Tastsensor 4 Komfort 1f KNX (model 504100) touch sensor for KNX building automation

The gira Tastsensor 4 Komfort 1f KNX (model 504100) is a KNX-compatible touch sensor designed for building automation. It features four capacitive touch zones within a single-frame System 55 format, enabling control of lighting, scenes and other KNX functions via the KNX bus. The device is intended for integration into residential and commercial installations where programmable and centralized control of lighting and automation scenes is required. The product supports responsive touch operation and can be configured via KNX engineering tools to trigger individual or grouped actions.

Advantages

The Gira Tastsensor 4 Komfort 1f KNX provides a compact four-zone touch interface that fits standard System 55 frames, enabling neat integration with modular switches and cover frames. Its KNX compatibility allows flexible logic and scene configuration using common KNX tools, while capacitive sensing delivers a modern, low-wear input method. The single-frame layout simplifies installation in environments where multiple functions are needed in a single location.

Suitable for

• Residential apartments and houses requiring centralized lighting and scene control.
• Offices and conference rooms where multiple functions (lighting, blinds, scenes) are controlled from one panel.
• Hotels, restaurants and public buildings with KNX-based automation systems.

When it may not be suitable

This touch sensor requires a KNX installation and appropriate KNX engineering for configuration; it is not suitable for standalone operation without a KNX bus. It also does not include conventional mechanical rocker switches, so installations that require tactile, large-format buttons or non-electronic legacy controls may prefer alternative hardware.

Key specifications

• Number of touch zones: 4 capacitive touch fields
• Mounting format: Single-frame compatible with System 55 cover frames
• Bus system: KNX communication for integration with building automation
• Control functions: Lighting control, scene activation and KNX function triggering
• User interface: Touch-sensitive surfaces with configurable feedback via KNX

How to use

Install the Tastsensor into a compatible System 55 frame and wire the KNX bus according to KNX installation guidelines. Use KNX engineering software (ETS) to assign group addresses, configure the touch zones and define actions such as switching loads, dimming lights or activating scenes. Once configured, operate the device by touching the capacitive zones; the connected KNX system will execute the programmed functions. Maintenance is limited to cleaning the surface with a soft, lint-free cloth and ensuring the KNX bus remains powered and correctly terminated.

What to consider before purchase

• Requires an existing KNX bus and KNX-compatible system for full functionality.
• Ensure compatibility with System 55 frames and the chosen cover frame design.
• Plan KNX group addressing and scene logic prior to installation for straightforward configuration.

Usage recommendations

Use KNX ETS to create clear, documented group addresses and scenes; label touch zones in system documentation or the visual layout so users understand each zone's function. For public or high-traffic areas, choose a robust cover frame and consider adding complementary visual indicators or central displays within the KNX system for status feedback.
