Building Automation with KNX

Flexible, Scalable, and Future-Proof

Modern building control calls for smart solutions that adapt to evolving needs. At Theben, we believe in the power of KNX – the global standard for intelligent building automation. Whether you’re specifying a new build, upgrading an existing facility, or looking to streamline multi-trade control in one system, KNX from Theben offers unmatched flexibility, integration, and reliability.

What is KNX?

KNX is an open, internationally recognised standard (ISO/IEC 14543) for building automation. It enables all technical systems in a building – including lighting, heating, ventilation, shading, security, and more – to work together intelligently.

From universities, office buildings and healthcare facilities to museums, hotels, and private homes, KNX can scale to fit any environment. All functions can be controlled automatically via sensors, manually via wall switches and control panels, or centrally using visualisation software – locally or remotely via smartphone or tablet.

Why Choose Theben for KNX?

As one of the original pioneers of KNX technology, Theben has been at the forefront of innovation for decades. We’re proud to be:

Today, we offer a full range of KNX-certified products designed for security, performance, and seamless integration, trusted by professionals across the globe.

Key Benefits of KNX Building Automation

Choosing KNX means choosing a future-proof system built to adapt and evolve. Here are just a few of the benefits:

Simplified planning, even for complex control requirements
Seamless integration across multiple trades and systems
Scalable and flexible – easily reprogrammed and extended
Central control and visualisation of building systems
Lower energy and operating costs through automation
Greater occupant comfort with intelligent control
High investment security thanks to a globally recognised open standard

Theben KNX Products

Our KNX range covers everything from everyday applications to high-spec custom solutions. All products are engineered for performance, longevity, and data security:

KNX presence and motion detectors – for efficient lighting and HVAC control
KNX actuators and RF actuators – reliable switching, dimming, heating and shutter control
KNX push-button interfaces – stylish, intuitive controls
Weather stations and sensors – for dynamic, weather-based control
KNX-DALI gateways – seamless lighting system integration

All KNX communication is protected by KNX Data Secure, offering strong defence against data tampering or unauthorised access.

Real-World Applications: What Can KNX Do?

With KNX, the possibilities are extensive:

Smart lighting with dimming, presence detection and orientation lighting
Blind and shutter control with sun tracking
Room climate management with CO₂ sensors
Temperature control via fan coil actuators
Energy optimisation across multi-use buildings

If you can imagine it, KNX from Theben can deliver it.

How It Works: The KNX System Architecture

Think of KNX as the nervous system of a building:

Sensors detect environmental changes (light, temperature, presence)
Actuators carry out commands (switching, dimming, heating, shading)
All devices communicate via the KNX bus – independent of the power supply

KNX supports multiple topologies – line, star, or tree – and is highly scalable. A single KNX installation can handle up to 58,000 devices, organised hierarchically with line and area couplers.

ETS: Engineering Tool Software for KNX

All KNX installations are programmed and configured using ETS (Engineering Tool Software) a powerful, manufacturer-independent tool developed by the KNX Association.

ETS enables full control over every device, scene and logic condition in a system. It also allows you to reprogram and reconfigure installations at any time, without rewiring or hardware changes.

Theben KNX devices are fully ETS-compatible and certified by independent test labs to ensure seamless integration and long-term reliability.

Built-in Security: KNX Data Secure

As buildings become smarter and more connected, so does the need for robust security. KNX Data Secure protects communication across the bus and RF devices against unauthorised access or tampering.

Theben was the first manufacturer worldwide to introduce KNX RF actuators with Data Secure in 2019 – and we continue to lead in this space with a full range of secure KNX devices.
