YOUR SMART KEY TO SECURE BUILDINGS
Modern buildings are complex digital ecosystems. Sensors communicate with actuators, control elements interact with gateways, and cloud services optimize processes in real time. This connectivity increases efficiency but also raises security requirements. This is exactly where KNX Secure by ABB comes in.
The certified extension of the KNX standard embeds cybersecurity consistently within building control. Encrypted communication, robust security mechanisms, and broad integration across relevant product lines create a level of protection that meets the demands of advancing digitalization.
WHY KNX SECURE IS INDISPENSABLE
This is where KNX Secure comes into play: IP Secure encrypts data transmission within the network, Data Secure protects telegrams exchanged between individual devices, and EN 50090‑4‑3 certification confirms the high security standard. This creates systems that are tamper‑proof, durable over the long term, and prepared for evolving requirements - across residential, commercial, and industrial buildings.
MORE CLARITY LESS COMPLEXITY
Instead of isolated solutions, we create a consistent, cross-discipline KNX system from a single source:
- Holistic planning: fewer interfaces, intuitive tools, and up to 30% time savings thanks to integrated planning
- Efficient operation: Smart load management, demand based control, and transparent energy flows help clearly reduce operating costs. based control, and transparent energy flows help clearly reduce operating costs.
- Standardized operating logic: touch panels, mobile applications, and switches are intuitive to use
- Future-ready: a scalable, adaptable system architecture - built to handle new technologies, changing re-quirements, and ESG standards.
SECURITY FROM THE SENSOR UP TO THE SYSTEM BOUNDARY
We understand security as an end‑to‑end system, not as a collection of individual devices, but as an architecture that extends from sensors and control elements to actuators and gateways, all the way to the system boundary. Presence detectors, switches, touch panels, actuators, couplers, and gateways work together to form a consistent, integrated whole. This is KNX Secure - a networked, expandable, and long‑term stable solution in which security is built in from the very beginning.
BRIDGE TO THE FUTURE: ABB Ability™ BuildingPro
BuildingPro expands this foundation with IoT-enabled building management. Lighting, shading, HVAC, energy, and comfort functions are all brought together on a single platform, accessible locally or via the cloud. This creates an ecosystem that unites security, efficiency, and transparency. BuildingPro provides the digital layer for future de-mands.
The ABB IQTouch is the central interface for modern buildings
Lighting, shading, room climate, scenes, and other functions can be clearly controlled and visualized. The user interface is deliberately minimalistic and logically structured. Information is easy to grasp , and everyday operation remains safe and intuitive. Depending on the application, the ABB IQTouch is available in two sizes: ABB IQTouch 7 and ABB IQTouch 10.
-
One panel, many possibilities
The ABB IQTouch combines building control and door communication in a single device. Functions can be consolidated, scenes flexibly adjusted, and processes clearly displayed. Energy values and air quality are visualized, supporting conscious use of resources and making building operation transparent.
-
Easily integrated, thoughtfully Installed
The ABB IQTouch fits into a standard flush-mounted box, simplifying planning, speeding up installation, and enabling reuse of existing wiring. With KNX Secure support and seamless system integration, it stays easily expandable. This makes it ideal for premium residential projects as well as commercial buildings, hotels, and utility facilities.
EFFICIENCY THROUGH PRECISION

KNX HF PRESENCE SENSOR
The high-frequency presence detectors respond reliably to motion and presence even in demanding environ-ments. They control lighting, air conditioning, and ventilation as needed, ensuring greater comfort while significantly reducing energy costs. Ideal for offices, corridors, sanitary areas, and auxiliary rooms.
Economical, compact, practical: Installation is now easier, and the more compact design is ideal for corridors, side rooms, and functional buildings - functionally streamlined and economically efficient.

KNX/MP BUS Gateway
The KNX/MP‑Bus gateway links KNX building automation with the Belimo MP‑Bus for efficient HVAC integration. A single bus line can control and monitor multiple valve and damper actuators as well as VAV controllers, reducing wiring and simplifying planning, installation, and commissioning.
The MP‑Bus provides feedback on position, operating status, and service data, while sensor values can be integrated directly and processed via KNX. Configured through ETS, the gateway offers a compact, scalable foundation for energy‑efficient HVAC concepts in commercial and industrial buildings.
-
KNX LINE COUPLER SECURE
Line couplers divide KNX networks into manageable segments, ensuring that even complex installations remain organized, stable, and scalable. They link individual lines, reduce bus load, and support architectural concepts for commercial, industrial, and multipurpose buildings, delivering reliability, security, and long-term expandabil-ity. purpose buildings term expandability.
KNX Data Secure is now available at the line level, allowing secured and unsecured lines to be combined within one installation - ideal for modern, segmented security concepts.
