The KNX interior sensors Intra-Sewi KNX are installed in a switch box or in the suspended ceiling. A valuable glass ring frames the recessed sensor unit. Intra-Sewi KNX has an independent design, but remains adequately restrained and easy to integrate.
With the Intra-Sewi KNX TH-Pr model, the presence detector forms the center of the device. At a mounting height of 2.50 m, movements are recorded segment by segment at approx. 7.40 m x 5.60 m. Circular fins ventilate the installation housing, in which temperature and humidity are measured.
The KNX device software offers limit values, mixed value calculations, logic modules and actuating variable comparators. There is a temperature control that regulates heating and cooling. A second PI control takes over the ventilation according to humidity. Thanks to these controls the room climate should always be ideal. Nevertheless, the so-called comfort field is additionally monitored and any deviation is reported to the KNX bus.
Other variants of the Intra-Sewi KNX measure only temperature or temperature and humidity. These devices only feature the software functions that match the sensors.
