Room temperature controller - Rymaskon Controller

The controller variants also have integrated controllers that can control all common actuators, damper drives or fan coils directly via the outputs and can therefore be used as stand-alone devices.
All values are made available to the building management system (BMS) via the Modbus or W-Modbus interface. If necessary, the BMS can intervene at short notice during operation and adjust parameters or prevent manual operation by the user by blocking individual functions.

Controller highlights:

- Stand-alone room temperature controller
- 24V or 230V power supply
- Outputs for controlling actuators, damper actuators, fan coils, etc.
- AO - 0...10V | DO - 24V (floating) | RO - 230V (floating)
- 2 inputs for an NTC10K, floating or floating 230V contact
- Modbus / W-Modbus for measurement/monitoring/control
- Temperature adjustment | fan adjustment | sun protection control | light control
- Internal sensors for temperature, humidity, CO2 and VOC
- Free software for configuration (USB-C)
- Mounted directly on the wall or on a flush-mounted box

All details at a glance

A room temperature controller forms the heart of an intelligent individual room control system. It ensures that each room is heated or cooled individually and energy-efficiently - as required.
With the Rymaskon controller, we offer you a powerful digital room controller that goes far beyond the functions of conventional systems.
Whether in a hotel room, a conference room or on a cruise ship, our room controller meets the highest requirements for precision, ease of use and integration into modern HVAC and BMS systems.

What is a room temperature controller - and why is it so important?

A room temperature controller is the central control element for the room climate. It continuously measures the temperature and transmits signals to the heating, cooling or ventilation system. This ensures that the desired temperature in the room is kept constant.
In the past, room controllers mainly consisted of analog thermostats - with a rotary knob and simple on/off function. These models are still used today in simple environments, but quickly reach their limits when it comes to comfort, flexibility or energy efficiency.
Modern room controllers such as the Rymaskon controller offer much more:

  • Precise control of temperature, humidity, CO₂ and VOC values
  • Communication via Modbus / W-Modbus with the building management system (BMS)
  • Control of additional functions such as ventilation, sun shading or lighting
  • Integration into smart building automation

This makes room temperature controllers an indispensable part of any modern HVAC system.

Areas of application for room temperature controllers

A room temperature controller such as the Rymaskon controller is useful wherever comfort, efficiency and reliability are required.

  • Hotels & Hospitality
    Each room can be controlled individually. Guests enjoy maximum flexibility and operators benefit from reduced energy costs.
  • Office and administration buildings
    Precise temperature control ensures constant conditions in meeting rooms, open-plan offices or executive floors - even with changing occupancy.
  • Cruise ships & yachts
    Complex air conditioning requirements are standard here. The digital room controller reliably controls the temperature and air quality even under extreme conditions.
  • Schools & universities
    Studies show: CO₂ levels in rooms affect the ability to concentrate. Rymaskon-Regulators with integrated air quality sensors sustainably improve the learning environment.
  • Hospitals & care facilities
    Here, an optimum indoor climate is not just a matter of comfort, but part of the hygiene and safety standards.
  • Industrial plants & special buildings
    From clean rooms to production halls - wherever precision counts, the Rymaskon-technology provides the necessary stability.

Thanks to wall or flush mounting and USB-C configuration, our room temperature controllers can be integrated flexibly and future-proof.

Buying a room thermostat - what you should look out for

Price is not the only decisive factor when buying a room thermostat. High-quality projects require digital room controllers that can be flexibly adapted and integrated into complex systems. Pay particular attention to:

  • Compatibility: Does the controller support Modbus / W-Modbus?
  • Sensors: Are temperature, humidity, CO₂ and VOC integrated?
  • Control: Which outputs (e.g. 0-10V, 24V, 230V) are available?
  • Installation & configuration: Wall or flush mounting? USB-C interface?
  • Durability: Can the device be updated and expanded?

Compared to inexpensive standard solutions, premium room controllers such as the Rymaskon controller offer a significantly greater range of functions, better energy efficiency and greater operational reliability.

What is a Rymaskon controller?

The Rymaskon controller is a sophisticated digital room temperature controller that has been specially developed for use in modern HVAC and building automation systems.
Unlike simple room controllers, it combines temperature control, air quality measurement and control of other functions such as ventilation, lighting or sun shading in just one device.
It is:

  • can be used as a stand-alone room controller,
  • fully BMS-compatible (Modbus / W-Modbus),
  • equipped with integrated sensors for temperature, humidity, CO₂ and VOC,
  • configurable via USB-C software,
  • and designed for demanding areas of application such as hotels, cruise ships, offices or clinics.

In short: the Rymaskon controller is more than just a room temperature controller - it is the central interface for an optimum room climate.
