Room temperature controller - Rymaskon Controller

The controller variants also feature integrated controllers that directly control all common servomotors, damper motors or fan coil units 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 required, the BMS can intervene at short notice during operation and adapt parameters, or prevent manual control by the user by blocking certain functions.

Controller highlights :

- Stand-alone room temperature controller
- 24V or 230V power supply
- Outputs for controlling servomotors, damper actuators, fan coil units, etc.
- AO - 0...10V | DO - 24V (potential-free) | RO - 230V (with potential)
- 2 inputs for one NTC10K contact, potential-free or with 230V potential
- Modbus / W-Modbus for measurement/control/command
- Temperature control | Ventilation control | Sun protection control | Lighting control
- Internal temperature, humidity, CO2 and VOC sensors
- Free configuration software (USB-C)
- Direct wall or back box mounting

Details at a glance

A room thermostat is the heart of intelligent individual control. It ensures that each room is heated or cooled individually and energy-efficiently - according to need. With the RYMASKON®Controller, we offer you a high-performance 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 demands for precision, ease of use and integration into modern HVAC and BMS systems.

What is a room thermostat - and why is it so important?

A room thermostat is the central control element for the room climate. It continuously measures the temperature and transmits signals to the heating, cooling or ventilation systems. In this way, it ensures that the desired temperature is constantly maintained in the room.
In the past, room controllers were mainly analog thermostats - with a rotary knob and a simple on/off function. These models are still used today in simple environments, but they quickly reach their limits when it comes to comfort, flexibility and energy efficiency.
Modern room controllers like the RYMLASKON® controllers offer much more:

  • Precise control of temperature, humidity and, depending on version, CO₂ and VOC values
  • Modbus / W-Modbus communication with building management systems (BMS)
  • Temperature control, additional options: ventilation, sun protection or lighting
  • Integration into intelligent home automation systems

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

Application areas for room temperature controllers

A room thermostat like the RYMLeASKON® controller is useful wherever comfort, efficiency and reliability are required.

  • Hotels & Hospitality
    Each room can be individually adjusted. Guests benefit from maximum flexibility, while operators benefit from reduced energy costs.
  • Office and administrative buildings
    Precise temperature control ensures constant conditions in meeting rooms, open-plan offices or executive floors, even when occupancy varies.
  • Cruise ships & yachts
    Here, complex air-conditioning requirements are standard. The digital room controller reliably controls temperature and air quality, even under extreme conditions.
  • Schools & universities
    Studies show: CO₂ content in rooms influences ability to concentrate. RYMLASKON®controllers with integrated air quality sensors sustainably improve the learning environment.
  • Hospitals & care facilities
    Here, an optimal indoor climate is not just a question of comfort, but also of hygiene and safety.
  • Industrial plants & special constructions
    From cleanrooms to manufacturing plants, wherever precision counts, ASKON® RYMtechnologyprovides the stability you need.

Thanks to wall or flush mounting and USB-C configuration, our room thermostats can be integrated flexibly and scalably.

Buying a room thermostat - what to look out for

When purchasing a room controller, price is not the only determining factor. 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 are available (e.g. 0-10V, 24V, 230V)?
  • Installation & configuration: Wall or flush mounting? USB-C interface ?
  • Long-term: can the device be upgraded and extended?

Compared with low-cost standard solutions, premium room controllers like the RYMASKON®Controller offer a much wider range of functions, greater energy efficiency and enhanced operating safety.

What is a Rymaskon® Controller?

The RYMASKON®Controller is a sophisticated digital room temperature controller, specially designed for use in modern HVAC and building automation systems. Unlike simple room controllers, it combines temperature regulation, air quality measurement and control of other functions such as ventilation, lighting or sun protection in a single device. It is

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

In short, the RYMASKON®Controller is more than a room temperature controller - it's the central interface for an optimal indoor climate.

    Depending on the model: temperature, humidity, CO₂ and VOC. External sensors can be connected in addition.
  4. How much energy can I save with a room thermostat?
    Empirical values show it: Using modern digital room controllers can save up to 30% on heating and cooling costs.
  5. Is it all digital?
    No - the RYMASKON®Controller offers both manual and centralized control via the BMS.
  6. What type of building is the ASKON® RYMControllerbest suited for?
    From hotels to cruise ships, office buildings to clinics, its flexibility means it can be adapted to almost any project.

How can Rymaskon® be integrated into home automation? Is wireless possible?

Thanks to intelligent Modbus communication, devices can be easily networked or integrated into existing building management systems. Room control modules supply setpoints to the BMS either via conventional wired Modbus, or via the wireless radio network. Wireless Modbus available.
RYMASKON®has sensors for measuring temperature, humidity and air quality to check the current state of the room. Room control modules control heating, cooling, ventilation, shading and lighting via Modbus communication with the BMS.

Conclusion: digital room controller for maximum efficiency

A modern room thermostat is much more than just a thermostat. It's part of intelligent, sustainable home automation. With RYMASKON®digital, you benefit from maximum efficiency, low operating costs and maximum operating comfort.
