  • Page 15: Comfort And Well-Being In Every Room

    Comfort and well-being in every room Most people in the industrial world spend 90 % of their time indoors. About one third of this time is spent at work. In this context it is clear that good indoor air quality, the right room temperature and draught- free air renewal are vital prerequisites for motivation and a sense of well-being.

  • Page 20: Applications

    Applications The scope of the RXB controllers is defined by the pre-programmed application modules. The following is an overview of the various applications and associated controllers. The controllers are shipped from the factory pre-programmed with a set of applications. The required application is then enabled with a tool (ETS3, ACS or the "HandyTool"). Due to the fact that the applications are largely pre-defined, engineering simply involves the definition of a small number of parameters, e.g.: •...
