The shape of the Suntracer RS485 pro ensures a turbulence-free air flow. The wind measurement is carried out on two horizontal sections offset by 90°. On each section, two signals are sent in the opposite direction shortly after each other. The speed and direction of flow are determined from the differences in the running time of the two axes.

An advantage of the process is the short reaction time, even with gusts and peak values. Changes of direction or strength are directly visible in the change of the measured value on the data bus. In this way can blinds, awning cloth and other wind-sensitive components be moved quickly into a safe position. 

If the wind direction is known in the building control system, the façades exposed to the wind can be specifically protected and costly wind damage avoided. The automatic shading and ventilation continues on the sides of the building facing away from the wind. Similar to the sun protection control, a compass direction profile is designed for the wind alarm and individual façade sections are controlled in a targeted manner. The often conflicting goals of protecting building elements and technology, offering the user comfort and opportunities for co-determination and optimising the building‘s energy efficiency are thus reconciled in the best possible way.
