• 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 façades and automatic activation / deactivation of the solar
protection of a façade during the time in which the sun shines on the respective façade
• 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 xture for diameter 48-60 mm
Wind alarm Yes
