The DEOS control systems GmbH (until 1st of July 2009 Plüth Regelsysteme GmbH) develops and produces, based on most modern technologies, intelligent and complete systems for the building automation and provides thus a maximum of energy saving and comfort in buildings. The systems are distributed and installed world-wide via system partners and our branches under the name COSMOS®. For years we are one of the leading innovators in the area of building automation - world-wide.
Consequently we belong among other things to the international leading system supplier in the area of the open protocol BACnet® - because we would like to commit our customers to us by our performance, and not by protocol-specific dependences. Since 2003 we develop and realize - as world-wide market leader - the optimization system BAopt, which can clearly reduce the energy consumption of ventilation systems and increase clearly the comfort. Due to our innovative products we evolved in the last years to one of the biggest German manufacturers of complete systems for the modern IP and Web-based building automation systems. One is completely important for us: we develop all core products ourselves, from sensors and actuators via DDC components through the building control system. As a result of this, we can guarantee the support for our products, to meet our partners requirements.


Status quo in 2009 the DEOS group employs more than 150 specialists of various trades, the average growth of our companies is considerably more than 30 % per year. Short decision ways, highly motivated and competent employees as well as fast reactions to the market requirements are your advantages as a partner of an owner controlled medium-sized company.

Our ultimate ambition is the enthusiasm of the COSMOS users and in this way the success of our partners. Therefore we stand abreast with large commitment to our partners to support them with solutions for solving also most challenging issues true to our company slogan: Building automation simply better!

P.S. DEOS stands for Digital Energy Optimizing Systems - and that is our passion!
