Optimum control requires accurate measurements A control operation is only as good as the measuring accuracy of the sensors which detect the control variable (temperature, humidity, pressure, etc.) and transmit it to the controller as an actual value. While this process hasn’t changed, the measuring technology and methods for mounting sensors are more cutting-edge than ever before. Legal regulations increasingly appeal for the economic use of energy.
Future-proof building control Everything you need for a good working climate Highlights Working concentrated while saving energy – products from Siemens improve the atmosphere in rooms and facilitate more economical operations. ■ ■ Saves The result: perfectly temperature-controlled and air-conditioned rooms with good lighting and reduced energy consumption.

Presence detectors (incl. brightness sensors) ■ ■ Make sure that the workplace is right in the detection zone of the presence detector – without any obstacles such as shelves, plants, glass walls, etc.
Room sensors for temperature, humidity and air quality To ensure accurate readings, it is a good idea to keep the following in mind during installation: Mounting guidelines for room sensors ■ ■ Mount room sensors in the living area at a height of approx.1.
Outdoor brightness sensors Mounting guidelines for outdoor brightness sensors ■ ■ When 18 19 Mounting guidelines selecting the mounting site, consider the part of the building (heating zone) for which the outdoor brightness sensor is to detect the incident sunlight; attach the sensor to the wall that contains the windows of the rooms to be affected ■ ■ Mount sensors in an accessible location (so they can be checked) ■ ■ Avoid shade due to trees, neighboring houses, etc.
Wind sensors Mounting guidelines for wind sensors ■ ■ Mount on the facade with the main wind direction a site on the building where the sensor can detect the wind unhindered ■ ■ Mount sensors in an accessible location (so they can be checked) ■ ■ Do not mount under eaves or balconies ■ ■ Do not place in alcoves ■ ■ Consider interference factors such as trees, shrubs and snow ■ ■ Best mounted on a pole ■ ■ Mount the sensor at least 60 cm from interference factors Main wind direction 20 21 Mounting gu
Door/window contacts Mounting guidelines for door/window contacts ■ ■ Mount 22 23 Mounting guidelines on the upper edge of the door or window to reliably detect and signal the reading even when the window is tilted open ■ ■ Attach the door/window contact to the stationary door/ window frame and mount the magnet on the moving door panel or window casement ■ ■ Make sure that the mounting plate and magnet are located in close vertical alignment – with a gap of at least 3 mm, but no more than 10 mm!
Weather stations/sensors (sun, wind, rain) The weather panels must be mounted on a pole or a vertical, south-facing wall. Pole mounting (recommended) Attach the bracket with the curved side facing the pole and the crosspiece facing down. Wall mounting Attach the bracket vertically with the flat side facing the wall and the half-moon crosspiece facing up.

Open communication standards In building control, open communication is important. It allows easy and secure integration of third-party systems on all levels. Support for multiple open standards ensures communication and facilitates efficient engineering. It also makes system maintenance and interoperability easier, thereby providing greater investment protection.
KNX KNX products for controlling lighting, shading and room climate as well as for energy management and security functions are characterized by easy installation and commissioning. The vendor-independent ETS Tool is used for commissioning. KNX is an international standard complying with the European Norm EN 50090, ISO/IEC 14543 and the Chinese standard (GB/Z 20965).
