Weather station
 Sensor for measuring wind speed, measuring range 2-30 m/s
 Three independent brightness sensors, measuring range 1-100 k Lux
 Consideration of up to two external brightness sensors
 Outdoor temperature sensor, measuring range -30 … +60°C
 Transmission of all measurement readings via the bus
 Monitoring of all measurement readings
 Consideration of the alignment of up to 3 facades and automatic activation / deactivation of the solar
protection of a facade during the time in which the sun shines on the respective facade
 Safety alarm for deactivating the solar protection, initiated by an external safety object or by logical
AND/ OR operations of the measured weather data
 4 threshold switches, independant of the weather data, each with 2 output objects
 6 logical AND, OR or XOR operations, independant of the whether data, of respectively up to 4 input
objects and each with 2 output objects
 Integrated bus coupling unit, bus connection via a bus terminal block
 As a compact unit for mast or wall mounting, including mast fixture for diameter 48-60 mm

Weather station
 Sensor for measuring wind speed, measuring range 2-30 m/s
 Three independent brightness sensors, measuring range 1-100000 Lux
 Consideration of up to two external brightness sensors
 Outdoor temperature sensor, measuring range -30 … +60°C
 Heated precipitation sensor
 Transmission of date and time via the bus
 Transmission of GPS position via the bus
 Transmission of all measurement readings via the bus
 Monitoring of all measurement readings
 Input of the geographical location of the installation site via the entry of longitude and latitude or
automatic detection via GPS
 Calculation and transmission of the angle data (azimuth and elevation) for current position of the sun
 Cconsideration of the alignment of up to 8 facades and automatic activation / deactivation of the solar
protection of a facade during the time in which the sun shines on the respective facade
 Sun tracking control of the slats position for solar protection, so that no direct sunshine, but as much
diffuse daylight as possible reaches the room
 Ssafety alarm for deactivating the solar protection, initiated by an external safety object or by logical
AND/ OR operations of the measured weather data
 4 threshold switches, independant of the weather data, each with 2 output objects
 6 logical AND, OR or XOR operations,independant of the weather data, of respectively up to 4 input
objects and each with 2 output objects
 External power supply of the heating for the precipitation sensor via 24 V DC, 210 mA
 Feed of the additional auxiliary power supply via the white / yellow twisted pair of the bus cable
 Integrated bus coupling unit, bus connection via a bus terminal block
 Compact unit for mast or wall mounting, including mast fixture for diameter 48-60 mm
