The black version is equipped with a dark lens.

Displays presence in desired RGB colour

The RGB LED acts as an status signal. When activated, the entire surface of the lens illuminated in colour. The colour can be selected individually. The brightness is adjustable in ten levels.

Ring segmentation

The presence detector usually detects a 360° area. Using the segment ring, individual areas of this detection range can be specifically covered so that the detector only reacts to movements in the desired zones.

Small installation depth

The shape of the KNX Mini presence detectors remains compact with unchanged installation dimensions that existing models can be easily replaced.

Faster configuration thanks to predefined function blocks in the ETS
Motion detector function block
Ideal for the use in corridors: the light switches on when people walk through the corridor and switches off again.
Presence detector function block
For example, for use in offices: light switches to office brightness when people are present.
Function block for heating, air conditioning, ventilation
It only switches the heating when someone is in the room. In air conditioning systems, the detector measures the dew point to protect the building from condensation.
Monitoring function block
The detector evaluates movements over a fixed time frame and only switches when a defined number of movements are detected. This means that the light remains switched off, if only the cat walks past.
Universal function block
Nothing is preconfigured in this block; all functions can be programmed individually here.

FAQ - Frequently Asked Questions about: KNX building technology

For new builds and refurbishment, the JUNG KNX system is regarded worldwide as one of the future-proof and manufacturer-independent solutions for building automation. The open KNX standard enables components from different manufacturers to be connected within a single system. This allows lighting, shading, heating and other functions to be controlled flexibly and centrally. This is a decisive advantage, particularly for long-term planned residential construction projects and demanding commercial buildings. The system remains expandable, replaceable and technically compatible. The smart home solution is not tied to a single provider and can grow with the requirements of the building. The open system therefore provides a flexible and long-term reliable foundation for complex building automation, particularly in larger construction projects and demanding architectural projects.

The JUNG KNX system can be combined with a wide range of high-quality switch ranges. They offer reliable KNX compatibility and combine design, functionality and long-term planning reliability with precision. This allows JUNG KNX solutions to integrate seamlessly into different architectural concepts while providing a technically sophisticated foundation for demanding smart home and building automation projects.

JUNG switch ranges stand for a clear, timeless design language, high-quality materials and a consistent design approach. They support planners in implementing a consistent switch design in KNX building automation.

Strengths of JUNG switch designs in KNX environments

  • High-quality materials and precise workmanship
  • Wide choice of colours, shapes and finishes
  • Reliable KNX compatibility
  • Harmonious integration into residential architecture, hotels and demanding commercial buildings
  • High planning and expansion reliability
  • Coherent combination of technology and design

With flush-mounted solutions, coordinated colour systems and a wide range of finishes, technical requirements can be translated into high-quality design. In addition, the exclusive Les Couleurs® Le Corbusier® colour range can be integrated into architectural colour concepts.

Durability, robustness and permanently precise mechanics represent quality in everyday use. Particularly in high-end residential and commercial buildings, solutions are created in which the technology does not take centre stage but integrates elegantly into the overall architectural concept.

JUNG combines functional precision with understated design, creating switch solutions that are convincing in KNX environments both technically and aesthetically, thereby providing a reliable foundation for modern smart home and building automation concepts.

A KNX system can be planned on a modular basis and built up step by step. It can also be expanded at any time. Additional functions such as KNX Secure, operating elements such as Smart Panel 8 or Smart Control 5, as well as display devices and visualisation solutions, are integrated according to the project requirements. This keeps the system flexible, future-proof and compatible with new applications and extensions over the long term.

KNX is an open, manufacturer-independent standard for building automation. This gives the system a high level of planning and investment security throughout all project phases. Unlike many proprietary solutions, KNX is particularly scalable and can be adapted flexibly to different building structures and usage scenarios.

The system can be combined with a wide variety of components and user interfaces, for example with switch ranges or proprietary smart home systems. JUNG HOME can be linked with KNX functions via the JUNG HOME Gateway and the Smart Visu Server and can therefore be integrated into a comprehensive building automation system.

For demanding construction projects, KNX is less a question of whether and more a question of when. As a manufacturer-independent, standardised bus system, KNX forms the technical backbone on which JUNG consistently builds its switching and control solutions. Planners and architects in particular benefit from clearly structured, scalable building automation.

  • Preserving property value
    A KNX bus system, once installed, remains functional for decades and can be expanded independently of the end devices used. This means the investment in the building infrastructure is protected over the long term and remains technically future-proof.
  • Scalability for large projects
    In buildings with a high level of technical complexity, such as hotels, hospitals or yachts, KNX demonstrates its strengths. A central bus cabling system replaces numerous individual control systems, making large installations easier to plan, clearly document and maintain over the long term.
  • Efficient building automation
    Lighting, shading and heating can be controlled centrally and according to demand instead of via separate individual systems. This supports certifications and sustainability assessments and creates a reliable foundation for efficient building technology. You can read how KNX can also be integrated with photovoltaic systems, heat pumps and wallboxes in the following question in the next section.

Tip for the initial installation
Anyone who plans a well-designed line structure and sufficiently sized distribution boards during the initial installation will avoid later conversions and retain maximum flexibility for future extensions to the KNX system. This simplifies the planning of complex projects and provides capacity for additional functions.

This is precisely one of the key advantages of an open bus system such as KNX: instead of several isolated standalone solutions with separate apps, all relevant energy components are controlled via a single platform.

  • Photovoltaic systems
    Via suitable interfaces, the inverter transmits its generation data to the KNX system. Consumers within the building can then be activated specifically when sufficient solar power is available.
  • Heat pump
    Many heat pumps have standardised interfaces through which they can be integrated into a KNX system. Operation can therefore be coordinated with current PV generation, occupant presence and time schedules.
  • Wallbox
    The charging capacity of a wallbox can also be integrated into a higher-level load management system via KNX. This allows charging processes to be shifted to periods with surplus PV generation and prevents peak loads at the building connection.
  • One system, one operating concept
    The decisive advantage for users is that whether controlling blinds, lighting, the heat pump or the wallbox, operation is carried out using the same JUNG switches, push-buttons or visualisations with central control. The design and operating concept remain consistent throughout.

For planning purposes, it is advisable to consider open, standardised interfaces for the energy components at an early stage. This ensures smooth KNX integration at a later stage and allows the various energy components to be integrated efficiently into the building concept.

Lighting and temperature demonstrate how intelligently the JUNG KNX system supports everyday life by combining comfort, security and energy efficiency.

  • Lighting scenes
    A single press of a button recalls a previously saved combination of brightness and colour temperature instead of controlling each light individually. Dimming is convenient and finely graduated to suit the respective usage scenario.
  • Presence simulation
    During periods of absence, for example while on holiday, the lighting switches on and off according to a realistic pattern. This makes the building appear occupied and an empty house significantly less unoccupied.
  • Room-by-room heating control
    Each room maintains its individually defined target temperature independently of neighbouring rooms. If someone opens a window, the control system responds automatically and adjusts the heating output accordingly.
  • Integration with schedules and sensors
    Blinds, heating and lighting can be linked to the time of day, outside temperature or the position of the sun. This enables the building to adapt automatically to current weather conditions and supports efficient, user-friendly building automation via KNX.

Yes, and over a long period. Devices from the first generation of KNX can still be combined with current components because the standard is continuously developed with backward compatibility. The ETS engineering software receives regular updates, while spare parts and extensions remain available for decades. For operators, this means that a system only needs to be planned once and does not have to be completely replaced every few years, but can continue to grow step by step.

For architecture and electrical planning, a consistent design is a strong argument in favour of JUNG as a manufacturer. KNX push-buttons such as F 10, F 40 or F 50 are not installed as separate, technical-looking elements, but are available in the same four switch ranges as the classic programmes: LS, A, AS and CD. Frames, rockers and covers remain identical. This allows conventional and smart switches to be installed side by side in the same room without creating a visual break in the wall design.

The selection is based on the same materials and colours as the classic ranges: depending on the series, frames and finishes are available in aluminium, stainless steel, chrome, gold or brass.

For manually operated push-buttons and the rotary sensor, there is an additional option: they are also available in the 63 original Les Couleurs® Le Corbusier® colours – the Polychromie Architecturale – hand-painted to create a particularly deep, matt colour effect.

Automatic components such as motion detectors, on the other hand, are available in the standard colours, where discreet, reliable functionality takes priority.

A special, usually green KNX bus cable is used for data transmission, a shielded two-core cable that is installed separately from the 230-volt power cables. This separation is not simply a nice-to-have, but protects the sensitive control signals from interference caused by the mains voltage. The number of these cable runs (lines) required in a building depends on its size. This should be determined during the electrical planning stage so that future extensions are not limited by insufficient cable capacity.

The basic principles of KNX are easy to understand, but detailed system planning should be carried out by a qualified system integrator. Using the ETS software, system integrators design KNX installations and link actuators and functions into a coherent overall system. For electrical planners, digital tools such as the JUNG KNX Configurator and integrated DIN rail (REG) data for CAE software significantly simplify the planning process, especially for larger projects with complex building automation requirements.

For homeowners, this means that you do not need to program KNX yourself. What matters is involving an experienced system integrator early in the planning process so that the desired functionality and future expandability of the system are considered from the outset.

The core of every KNX installation is the actuator. Actuators convert incoming control commands into switching actions, forming the central interface between system planning and the building's technical equipment.

  • Switch actuators control lighting and other electrical loads. They are available with different channel configurations, making them suitable for both small residential projects and large-scale commercial installations.
  • Blind actuators precisely and reliably control the movement and slat position of roller shutters, venetian blinds and awnings.
  • Heating actuators control thermal actuators for underfloor heating systems and radiators on a room-by-room basis, enabling precise individual temperature control in different zones.
