This object type is enabled in the default interface. It can be disabled.
8.2.9.1 Glare Protection
The sunblind controller can automatically control the connected sunblind actuator to
provide glare protection. To do so the sunblind controller needs to know the geometry of
the sunblind blades.
Figure 224: Sunblind Geometry
The blade distance (D) has to be configured in the configuration property nciBladeDist and
the blade width in nciBladeWidth. The minimum and maximum rotation angle (α) is
configured in nciMinRot and nciMaxRot. Based on this geometry data and the current sun
elevation (nviSunElevation) the glare protection algorithm calculates the rotation angle for
the blades. The rotation angle can be optimized for a specific sunblind type by specifying an
offset in the configuration property nciRotOffset.
The following parameters determine if glare protection is necessary:
