Room operating units - Rymaskon Interface

The interface (room operating unit) is used to display and set the actual and setpoint values of a room. The values are made available to the building management system (BMS) via the Modbus or W-Modbus interface.
Temperature setpoint and fan levels, 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 / W-Modbus (wireless) for recording room values and for higher-level monitoring/control
- Temperature adjustment | fan adjustment | sunshade control | lighting control
- Internal sensors for temperature, humidity, CO2 and VOC
- Free and user-friendly software for configuration (via USB-C)
- Mounted directly on the wall or on a flush-mounted box

What is a room operating unit?

A room operating unit is the central interface between people and modern building automation. It measures important room parameters such as temperature, humidity or CO₂ and simultaneously enables the input of set 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 every smart building.

Important: A room operating unit does not work independently, but functions exclusively as an operating and display unit in combination with the building management system (BMS). The actual evaluation of the measured values and the regulation and control of the connected systems is only carried out by the BMS.

Why use a room operating unit?

Room operating units improve comfort, optimize the room climate and help to use energy efficiently. Users benefit from intuitive control, while building management receives precise data to optimize the building technology.

Typical functions:

  • Convenient temperature control
  • Light and blind control
  • Display of room statuses (e.g. temperature, humidity, CO₂)
  • Time-controlled scenarios
  • Integration into smart building concepts

What are typical challenges with operating devices?

Many conventional room operating devices reach their limits: insufficient accuracy, limited compatibility, complicated operation or time-consuming installation. A lack of interfaces to modern building management systems or no support for wireless communication are also common problems in practice.

What is a Rymaskon interface?

The Rymaskon interface is the innovative answer to modern requirements for room operating units. It combines high-precision sensor technology with intuitive operation and supports protocols such as Modbus and W-Modbus (Wireless Modbus). Thanks to a modular concept, the interface can be configured flexibly - for new buildings as well as for retrofit projects.

  • 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 - for all types of buildings:

  • Office buildings & administration centers
  • Hotels & hospitality
  • Schools & educational institutions
  • Hospitals, clinics & nursing homes
  • Residential complexes, apartment buildings and smart homes
  • Industrial buildings & manufacturing

How can Rymaskon be integrated into building automation?

Thanks to intelligent Modbus communication, the devices can be easily networked or seamlessly integrated into existing building management systems. The room operating units provide the BMS with the setpoints either via the conventionally wired Modbus or via the wireless, radio-based Wireless Modbus wireless system.
Rymaskon The room operating units are equipped with sensors to measure temperature, humidity and air quality in order to check the current status of the room. The room operating units control heating, cooling, ventilation, shading and lighting via Modbus communication with the BMS.
