II. sun protection with shading control and fixed sun protection positions:
The shading control of the weather station is used. When the preset basic brightness for shading
operations is exceeded, the weather station transmits a 1-bit telegram of value "1" via the "Shading
facade [shading control facades 1-4]" to the bus. The switching/shutter actuator activates the shading
function and adjusts the curtain to the corresponding fixed sun protection position. In the operating
mode "Blind" of the switching/shutter actuator, the fixed slat position specified in the parameter is
recalled in addition.
When the brightness drops below the basic brightness for shading operations (with hysteresis, if
programmed), the weather station transmits a "0" telegram to the bus. This deactivates the shading
function in the switching/shutter actuator and the corresponding reaction at the end of sunshine
/shading will be executed. The communication objects must be linked as shown in Fig. 36.
Required parameterization of the switching/shutter actuator (parameters not listed are optional):
- polarity of the "Sunshine / shading facade" object = "1" sunshine,
- reaction at the beginning of sunshine / shading = fixed position,
- fixed positions setting.
