COMPACT WSC11 BR=192, ID =30, TT=0, SH= 3001 2 Application The WEATHER STATION COMPACT WSC11 is designed for use in building services auto- mation systems (e.g. shade protection control). The WSC11 features the following measured variables: • Wind speed. -
Page 6: Setup And Mode Of Operation
3 Setup and Mode of Operation Wind Speed / Wind Direction Wind measurement is based on the hot wire principle. The underside of the housing is equipped with a heated cylindrical sensor. A PID controller adjusts the temperature of the cylinder to a temperature that is constantly increased in relation to the environment. -

Figure 2: Diagram, evaluation characteristic position of the sun Please see additional Figure 4: Spectrum of Brightness Sensors Twilight Twilight means the light diffusion in the atmosphere, which arises with the smooth transition between day and night before the beginning or after the end of day. i.e., the solar disc is not visible. - Page 8 To make a meaningful comparison between air pressure values simultaneously measured at different locations, they need to be converted to a common datum (height above sea level). The calculation is referred to the height above sea level (QNH) according to the inter- national altitude formula (DIN ISO2533).
- Page 9 Time / date and geostationary data The Weather Station has a GPS receiver with a built-in RTC. This allows it to receive the po- sition of the Weather Station (degree of longitude/latitude, local altitude) time (UTC) and date. The GPS receiver does not needs alignment. The built-in RTC (Real Time Clock) is buffered with a backup capacitor and retains its data without a voltage supply for a period of minimum 3 days.

Page 16: Interface
6 Interface The interface to the Weather Station consists of a RS485 link (half-duplex mode), with the following data format: • 9600baud (the baud rate can be selected with the Command BR). • 8data bits. • No parity. • 1stop bit. •... - Page 17 Commands can be transmitted with or without a parameter. If no parameter is specified, the set value will be output. Example: 00BR<CR> !00BR00005<CR> If a command is transmitted with a parameter, the parameter is verified. If it is valid, it will be saved and specified in the echo telegram.
