JUNG 2224WH KNX

Application purpose
The KNX weather station records the meteorological data wind speed, precipitation, twilight, temperature and three times the brightness depending on the direction. The main area of application is automatic, weather-dependent shading control. It is specially designed for the home. To increase functional reliability, the weather station monitors itself in some important functions and reports corresponding errors independently via signalling objects on the bus. It is designed for outdoor installation on a mast or wall. The bus connection to the KNX is integrated. The data itself, in particular the limit value processing, is already analysed in the weather station. It is protected against impairment of the function by frost and condensation by an integrated heater down to -20 °C. The heating also ensures that the sensor surface of the precipitation sensor dries quickly after rain or defrosts in the event of snow and ice. With the exception of the heating and the power supply to the precipitation sensor, the unit is supplied by the bus. The weather station requires an external 24 V AC/DC power supply for the heating, without which precipitation detection is not possible. Logic gates are available for cascading several weather stations and for linking the limit values and monitoring functions. Blocking elements enable individual functions to be blocked on site.

Intended use
Measurement and evaluation of weather data: Wind speed, precipitation, twilight, temperature and brightness. Vertical installation on the outside of buildings, preferably on roofs and façades.
