Siemens Smart Infrastructure’s RDG200 thermostat can now monitor and control indoor air quality

  • RDG200 thermostat now equipped with a built-in CO2 sensor for monitoring and controlling indoor air quality
  • Helps provide a healthy indoor climate and a safe place to work
  • Achieves high energy efficiency and reduced energy costs

(PRESS RELEASE) ZUG, 14-Jul-2022 — /EuropaWire/ — Siemens Smart Infrastructure, Siemens AG’s company for intelligent, adaptive infrastructure, has announced that the company’s RDG200 thermostat series will now offer a model that is natively equipped with a CO2 sensor and control functions, which will monitor and control indoor air quality to ensure a healthy and productive indoor air climate for people in the building, while maintaining efficient operation. For instance, when the air quality deteriorates due to the rise of the CO2 concentration, the ventilation system will then automatically adjust and ensure that the right amount of fresh air is provided to the space.

The system thermostat can be natively integrated into Synco and Desigo systems from Siemens or into third-party systems thanks to its open KNX communication capability. With its new CO 2 features, RDG200 not only ensures adequate ventilation when space occupancy is high, but also ramps ventilation down when CO 2 concentration is low, thereby supporting energy-saving strategies in the room. A wide range of preloaded applications provides a multitude of options for sustainable room automation. The on-screen display informs the building user on the current CO 2 status of the room. The one-touch “Green Leaf” function increases user awareness and promotes action to operate the space in the most energy efficient manner.

According to a study by the U.S. Environmental Protection Agency, poor ventilation may account for more than 50 percent of all sick leave, and poor indoor air quality noticeably decreases office work performance. Additionally, the pandemic has raised awareness for the importance of indoor air quality in offices, but also in buildings like schools and universities.

Thermostats customized to any building need

The extensive thermostat portfolio from Siemens ranges from simple mechanical and digital room thermostats for basic room climate control to advanced communicating thermostats for integration into building automation systems. With their versatile outputs, the RDG200 thermostats cover most installation needs, including heating and cooling, fan coils and variable air volume. The compact all-in-one thermostats with large displays and multifunctional built-in sensors are easy to install and commission and support cost-effective room automation solutions.
