When designing a KNX project, the space inside the electrical distribution board is often a luxury. More devices mean more space, more wiring, and higher installation costs. JUNG addresses this challenge directly with its KNX Multi Stations, introduced in late 2025, available in two versions: the Standard and the Universal. Both devices are designed to combine lighting, blind, heating, and scene control into a single, compact housing — drastically simplifying both planning and commissioning.
The Standard Choice: KNX Multi Station
Designed for standard applications in residential and functional buildings, the Standard version (2570 M1 SR) is a 4-rail unit powerhouse of efficiency. It offers eight outputs — 2 dimming channels and 6 relay outputs — allowing lighting, blinds, and valve drives to be combined flexibly. What sets it apart is the inclusion of two integrated HVAC controllers, enabling precise control of room temperature, fan levels, and shading directly from the actuator.
The Heavy-Duty Solution: KNX Multi Station Universal
For projects with complex HVAC requirements, the Universal version (2590 M1 SR) steps up. Occupying an 8-rail unit, it packs 17 outputs into a single device: 4 dimming channels, 10 relay outputs, and 3 analogue outputs (0–10 V). These analogue outputs are ideal for directly controlling EC fans or continuous valve drives without extra modules.
Beyond its output capacity, the Universal model includes comprehensive protection and diagnostic functions. Features like overload monitoring and mains voltage failure monitoring ensure reliable operation, even in complex and demanding building systems.
Real-World Application: The Complete Hotel Room
The true value of this consolidation becomes clear in demanding environments like hospitality. Instead of filling a control cabinet with multiple individual actuators, a complete hotel room can be controlled with just a single multi station.
From the bedside switch, guests can effortlessly manage lighting scenes, adjust the room temperature, control the blinds, and activate privacy modes. Behind the scenes, all these operations are routed through a single, compact JUNG multi station, ensuring a seamless, quiet, and reliable operation for the guest while keeping the electrical room perfectly organized.
Why Integrators and Planners Benefit
- Space Saving: Replaces a rack of individual actuators with one neat unit.
- Cost Reduction: Less wiring, fewer terminal blocks, and significantly reduced labor time during installation.
- Built-in Security: Both variants are fully compatible with KNX Secure, ensuring end-to-end encryption for building data.
By merging multiple actuators into one, JUNG continues to prove that efficient engineering doesn’t have to compromise on capability. For system integrators looking to optimize control cabinets and for energy consultants aiming for precise HVAC regulation, these multi-stations provide a highly competitive, future-proof foundation.
