As a core component of EAE’s renowned KNX product family, this device is engineered to simplify complex electrical installations and consolidate multiple control functions into a single, compact, and powerful unit. The RCU2000 is a versatile, all-in-one device that is designed to meet the rigorous demands of modern electrical projects across a wide range of applications, from smart residential homes and luxury hotels to advanced commercial buildings and healthcare facilities. By centralizing control for lighting, climate, and blinds, the RCU2000 not only streamlines wiring but also provides a robust and intelligent platform for managing a room’s entire electrical ecosystem.

In-Depth Features and Technical Specifications

The RCU2000 is a highly versatile KNX device, designed for easy mounting on a DIN rail within an electrical cabinet. The “RCU” in its name signifies “Room Control Unit,” and the model number “2000” reflects its powerful capabilities. A key advantage of this unit is its operational efficiency; it is powered directly by the KNX bus and does not require an auxiliary power supply, which significantly simplifies the installation process and reduces component count.

• High-Capacity Switching: The RCU2000 is equipped with 20 independent relay outputs, each rated at a robust 16A. This makes it an incredibly powerful solution capable of controlling a wide variety of loads. It is certified to switch resistive, capacitive, and inductive loads in compliance with the EN 60669 standard, making it ideal for controlling modern LED lighting, fluorescent lamps, and other diverse electrical devices. The unit offers a maximum switching power of 4000 VA and boasts a long mechanical life, with over a million switching operations, ensuring long-term reliability.
• Flexible Control Capabilities: The RCU2000’s outputs are intelligently grouped into five independent channels, each of which can be configured for a specific operational mode. This flexibility is a critical feature that allows a single device to perform a variety of functions, including:
  • Switching Output: Provides up to four independent switching channels for basic on/off control of lights and other electrical loads.
  • AC Blind Control: Manages two-channel AC-powered blinds, shutters, and curtains.
  • DC Blind Control: Offers one-channel control for DC-powered blinds.
  • 2-Point Valve Control: Provides two channels for the precise control of two-pipe fan coil units.
  • 3-Point Valve Control: Manages one channel for more complex three-pipe fan coil systems.
• Advanced Integrated Logic: The RCU2000 is far more than just a simple relay module. It includes a suite of integrated, programmable functions that add a layer of intelligence and sophistication to a building’s automation system. These features include:
  • Staircase Lighting Function: Automates lighting in stairwells, combining convenience with energy savings.
  • External and Internal Logic Functions: Allows for the creation of complex, customized automation scenarios based on inputs from other KNX devices.
  • Priority Function: Assigns priority to specific commands, ensuring that critical functions are executed without interruption.
  • Threshold Function: Triggers actions when a pre-defined threshold is met (e.g., turning on lights when a brightness sensor detects low light levels).
  • Operating Hour and Sweep Functions: Useful for tracking device usage for maintenance purposes and for scheduling automatic cleaning cycles.

Diverse Application Scenarios

The RCU2000’s all-in-one design and extensive functionality make it an excellent solution for a wide range of applications, drastically reducing the number of individual devices required and simplifying the overall wiring scheme.

• Hotel Guest Rooms: In the competitive hospitality sector, the RCU2000 can serve as the central brain for a hotel room’s management system. By integrating with a Guest Room Management System (GRMS), it can automatically create welcoming scenes when a guest enters, manage climate control to save energy when they leave, and handle “Do Not Disturb” notifications. This not only significantly enhances the guest experience but also leads to substantial energy cost reductions for the hotel.
• Healthcare Facilities: In hospitals and clinics, where precise control and reliability are non-negotiable, the RCU2000 can manage lighting, blinds, and climate control in patient rooms. It simplifies controls for medical staff while ensuring a comfortable and hygienic environment for patients.
• Residential Homes and Apartments: For smart homes, the RCU2000 serves as a core electrical hub for each room. It can automate complex lighting scenes, synchronize blinds with sunrise and sunset, and integrate with a central thermostat to optimize heating and cooling. This provides homeowners with unparalleled convenience and energy efficiency.
