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.

The Building Automation section of Siemens Building Technologies holds a library of applications, which is continuously being expanded (see Overview, page 10). For the engineering and commissioning of a network of RXB controllers, use is made of...
Page 17: Coordinated Room Controllers
Coordinated room controllers RXB21.1 and RXB22.1 compact room controllers for fan-coil units The input/output configuration and mounting options of these room controller s makes them ideal for fan coil applications. They can be installed in fan coil units, in control panels or on ducting.
Page 18: The Room Units: The Key To Individual Comfort
The room units: the key to individual comfort The room units of the RXB range cover the widely varying requirements of individual room occupants. When designing these stylish room units, the designers also paid special attention to ergonomic factors. The HVAC system, lighting and blinds can be operated in various ways: •...

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.: •...
Page 21: Installation
Installation The RXB controllers are designed for various types of installation (mounted with screws or on DIN rail): • In fan coil units • In control panels • In ceiling voids • Under floors • In sill or floor ducting. 01654 Various options for installation Terminal covers are required when mounting the controllers outside control panels or...

The RXB controllers are compatible with the DESIGO and Synco systems from RXB controller Siemens Building Technologies. The communications component on the RXB controllers are based on Konnex technology and support the S-mode and LTE mode. The devices are certified for Konnex and are labeled with the KNX logo.
