The DEOS control systems GmbH (until 1^st 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.

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

We are one of the international technology leaders in the field of the high energy-efficient building automation systems.
