Room temperature controller - Rymaskon Controller

The controller models also feature integrated controllers that directly control all common actuators, damper actuators, or fan coils via their outputs, allowing them to be used as stand-alone devices. All values are made available to the building management system (BMS) via the Modbus, W-Modbus, BACnet, or W-BACnet interface. If necessary, the BMS can intervene temporarily during operation to adjust parameters or prevent manual operation by the user by disabling 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 (voltage-free) | RO - 230V (voltage-carrying) - 2 inputs for an NTC10K, a potential-free or potential-carrying 230V contact - Modbus / BACnet / W-Modbus / W-BACnet for measurement/monitoring/control - Temperature adjustment | Fan speed adjustment | Sunshade control | Lighting control - Internal sensors for temperature, humidity, CO2, and VOC - Free configuration software (USB-C) - Mounts directly on the wall or in a flush-mounted box

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

A room temperature controller is the central control element for the indoor climate. It continuously measures the temperature and sends signals to the heating, cooling, or ventilation systems. This ensures that the desired temperature in the room is maintained at a constant level. In the past, room controllers consisted mainly of analog thermostats—with a rotary knob and a simple on/off function. These models are still in use today in basic settings, but they quickly reach their limits when it comes to comfort, flexibility, or energy efficiency. Modern room controllers such as the RYMASKON® controllers offer significantly more:

  • Precise control of temperature, humidity, and—depending on the version—CO₂ and VOC levels
  • Communication via Modbus / BACnet / W-Modbus / W-BACnet with the building management system (BMS)
  • Control of temperature; additional options include: ventilation, sun protection, or lighting
  • Integration into smart building automation

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

Applications for Room Temperature Controllers

A room temperature controller such as the RYMASKON® Controller is ideal for any application where comfort, efficiency, and reliability are required.

  • Hotels & Hospitality Each room can be controlled individually. Guests enjoy maximum flexibility, and operators benefit from lower energy costs.
  • Office and Administrative Buildings: Precise temperature control ensures consistent conditions in conference rooms, open-plan offices, and executive suites—even when occupancy levels fluctuate.
  • Cruise Ships & Yachts: Complex climate control requirements are the norm here. The digital room controller reliably regulates temperature and air quality even under extreme conditions.
  • Schools & Universities: Studies show that CO₂ levels in rooms affect the ability to concentrate. RYMASKON® controllers with built-in air quality sensors provide lasting improvements to the learning environment.
  • Hospitals & Care Facilities: An optimal indoor climate here is not just a matter of comfort, but part of hygiene and safety standards.
  • Industrial Facilities & Special-Purpose Structures From cleanrooms to manufacturing facilities—anywhere precision matters, the RYMASKON® technology provides the necessary stability.

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

Buying a Room Thermostat – What to Look For

When purchasing a room controller, price isn't the only factor to consider. High-quality projects require digital room controllers that can be flexibly customized and integrated into complex systems. Pay special attention to:

  • Compatibility: Does the controller support Modbus / BACnet / W-Modbus / W-BACnet?
  • Sensors: Are temperature, humidity, CO₂, and VOC sensors built in?
  • Control: What types of outputs (e.g., 0–10 V, 24 V, 230 V) are available?
  • Installation & Configuration: Surface-mount or flush-mount? USB-C port?
  • Long-term viability: Can the device be updated and upgraded?

Compared to low-cost standard solutions, premium room controllers such as the RYMASKON® controllers offer significantly greater functionality, improved energy efficiency, and enhanced operational reliability.

What is a Rymaskon® controller?

The RYMThe ASKON® Controller is a state-of-the-art digital room temperature controller designed specifically 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 protection—all in a single device. It is:

  • can be used as a standalone room controller,
  • Fully GLT-compatible (Modbus / BACnet / W-Modbus / W-BACnet),
  • equipped with built-in sensors for temperature, humidity, CO₂, and VOCs,
  • configurable via USB-C software,
  • and designed for demanding environments such as hotels, cruise ships, offices, or clinics.

Frequently asked questions (FAQ) about room temperature controllers

  1. What is the difference between a thermostat and a room temperature controller? A thermostat measures the temperature and simply controls a heating valve. A modern digital room temperature controller, such as the RYMASKON® handles significantly more functions: ventilation, sun protection, lighting, and building management system (BMS) communication.
  2. Which interfaces are supported RYMASKON® controllers? All models feature Modbus / BACnet / W-Modbus / W-BACnet. This ensures seamless integration into the building management system.
  3. What sensors are built in? Depending on the model: temperature, humidity, CO₂, and VOC. External sensors can also be connected.
  4. How much energy can I save with a room temperature controller? Experience shows that using modern digital room temperature controllers can reduce heating and cooling costs by up to 30%.
  5. Is digital operation the only option? No—the RYMASKON® Controller offers both manual operation and centralized control via the building management system (BMS).
  6. For which types of buildings is the RYMASKON® Controller? From hotels and cruise ships to office buildings and clinics—its flexibility makes it suitable for virtually any project.

How do I integrate Rymaskon® in building automation? Is wireless possible?

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

Conclusion: Digital room controller for maximum efficiency

A modern room temperature controller is more than just a thermostat. It is part of a smart, sustainable building automation system. With the RYMWith ASKON® digital room controllers, you benefit from maximum efficiency, reduced operating costs, and the highest level of user comfort. Whether in a hotel, office, or industrial facility—with our solution, you can rely on precise control that makes your HVAC systems ready for the future.
