The worldwide standard for home and building control Manual for KNX Planning siemens.
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.

Room sensors for temperature, humidity and air quality Mounting guidelines for sensors measuring room temperature, relative humidity and air quality • Mount sensors in rooms at a height of approx. 1.
In products from Siemens, the sensors within the devices are located before the wall so that the rising air flow can be accurately measured. To ensure accurate readings, it is a good idea to keep the following in mind during installation: Clearances between the cable (4) or plastic hose and the installation pipe (5) need to be sealed. Otherwise, inefficient air circulation will occur, causing measuring errors.
