Optimum control requires accurate measurements This manual was written by practitioners for practitioners and has become a popular and indispensable reference book over the last few years. Legal regulations increasingly appeal for the economic use of energy. At the same time, the indoor climate must meet stringent requirements. Both requirements can be fully met only if all necessary measured data are available and the sensors remain absolutely reliable year after year.
Future-proof building control Everything you need for a good working climate Working concentrated while saving energy – products from Siemens improve the atmosphere in rooms and facilitate more economical operations. The result: perfectly temperature-controlled and airconditioned rooms with good lighting and reduced energy consumption.

Modern topology In this modern topology, the backbone couplers are replaced with N 146/02 IP routers. Thanks to the use of standard network components, the connection for example of two building sections is no longer limited to bus line lengths. Use of other media such as fiberoptic cabling or WLAN is also possible for the purpose of coupling distant buildings and exchanging group address telegrams.
