Room operating units - Rymaskon Interface

The interface (room control unit) is used to display and adjust the actual and setpoint values for a room. The values are made available to the building management system (BMS) via the Modbus, W-Modbus, BACnet, or W-BACnet interface. The temperature setpoint and fan speeds, as well as sun protection and lighting, can be set by the user directly on the device or specified by the BMS. Interface Highlights: - Modbus / BACnet / W-Modbus (wireless) / W-BACnet (wireless) for monitoring room parameters and for higher-level control - Temperature adjustment | Fan speed adjustment | Sunshade control | Lighting control - Internal sensors for temperature, humidity, CO₂, and VOCs - Free and user-friendly configuration software (via USB-C) - Mounting directly on the wall or in a flush-mounted box

What is a room operating unit?

A room control unit serves as the central interface between people and modern building automation. It measures key room parameters such as temperature, humidity, and CO₂, while also allowing users to set target values for functions such as:

  • Heating and Cooling
  • Ventilation
  • Light
  • Shading
  • Scene Control

Modern devices combine sensors, actuators, and displays in a compact, wall-mounted housing—making them an essential component of any smart building.

Important: A room control unit does not operate independently; rather, it functions solely as a control and display unit in conjunction with the building management system (BMS). It is the BMS that actually evaluates the measured values and regulates and controls the connected systems.

Why use a room control unit?

Room control devices enhance comfort, optimize the indoor climate, and help ensure efficient energy use. Users benefit from intuitive controls, while building management receives precise data to optimize building systems.

Typical features:

  • Convenient Temperature Control
  • Lighting and Blind Control
  • Display of room conditions (e.g., temperature, humidity, CO₂)
  • Time-Based Scenarios
  • Integration into Smart Building Concepts

What are some common challenges with control devices?

Many conventional room control devices have their limitations: insufficient accuracy, limited compatibility, complicated operation, or time-consuming installation. The lack of interfaces to modern building management systems or support for wireless communication also pose frequent problems in practice.

What is a Rymaskon® interface?

The Rymaskon interface is the innovative solution to modern requirements for room control devices. It combines high-precision sensor technology with intuitive operation and supports protocols such as Modbus, BACnet, W-Modbus (Wireless Modbus) and W-BACnet (Wireless BACnet). Thanks to its modular design, the interface can be flexibly configured—for both new construction and retrofit projects.

Your advantages:

  • Increase energy efficiency through precise measurement and optimized control strategies
  • Reduce operating costs through intelligent automation and maintenance reduction with the help of Rymaskon and the BMS
  • Reduce wear and tear of HVAC components thanks to demand-based control and the appliance itself by using fewer mechanical elements with less wear and a longer service life.
  • Save time during commissioning and integration thanks to sophisticated interfaces and the option of pre-configuration from the comfort of your desk - no more annoying on-site settings!
  • Future-proof investment with a scalable and updatable system

Areas of application

The RYMASKON® Interface is versatile and can be used in all types of buildings:

  • Office Buildings & Administrative Centers
  • Hotels & Hospitality
  • Schools & Educational Institutions
  • Hospitals, Clinics, and Nursing Homes
  • Residential complexes, apartment buildings, and smart homes
  • Industrial Buildings & Manufacturing

How can Rymaskon be integrated into building automation?

Thanks to intelligent Modbus and BACnet communication, the devices can be easily networked or seamlessly integrated into existing building management systems. The room control units transmit setpoints to the BMS either via conventionally wired Modbus or BACnet, or via the wireless, radio-based W-Modbus or W-BACnet.

RYMASKON® is equipped with sensors for measuring temperature, humidity, and air quality to monitor the current conditions in the room. The room control units control heating, cooling, ventilation, shading, and lighting via Modbus or BACnet communication with the building management system (BMS).
