The KNX weather Station Plus includes wind speed, wind direction, precipitation, global radiation, temperature, twilight, relative humidity and air pressure as well as determining brightness directionally with four sensors. The measured data is used to calculate the maximum value for the brightness sensors, the absolute humidity, the felt temperature and the comfort level. The weather station is self-monitoring and reports suitable errors. The weather data can be displayed on the associated KNX operating panels and can be used, for example, to control the shading of up to eight building façades. Logic, blocking, and limit value functions are integrated. The installed GPS/GLONASS receiver delivers the exact time of day as well as geo-data for determining the sun conditions. The KNX Weather Station appears compact and unobtrusive in every installation situation. Commissioning is performed via ETS software.
