The KNX Basic weather station records weather data, analyses these and can transmit them to the bus. The device has a wind sensor, precipitation sensor, temperature sensor and 3 brightness sensors. -Self contained outdoor weather station. For measuring wind, rain, brightness and temperature. For fully automatic blinds and sun protection control with automatic adjustment of blinds according to position of the sun. Rain sensor with integrated heating. The weather station can also be operated without mains supply. The heating of the rain sensor will not function then. Measurement and evaluation directly on device. Sun protection for up to three facades via 3 integrated brightness sensors. 8 sun protection channels. 4 additional threshold channels for connection of external KNX sensors. 6 logic channels. Display of weather data on visualisation. Suitable for mounting on an outside wall or with optional accessories on a corner or on a mast. With integrated bus coupler. The bus is connected using a bus connecting terminal. An additional AC 230 V power supply is required for the heating unit. KNX software functions: Adjustment of slat position according to current position of the sun. Sun protection area both horizontal (azimuth) and vertical (elevation) can be set exactly. 3 installed brightness sensors at 90° spacing. 2 objects for external brightness sensors. Shading can be temporarily interrupted via object. Universal channels with AND/OR linking of weather parameters. Threshold channels with delay with falling below and exceeding. Logic channels with 4 input objects + internal link that can be configured with status of the universal and threshold channels. Power supply: AC 110-230 V, 50-60 Hz.
