Slat Angle
Type: real number
If WindowShadingControl referencing the window that incorporates this blind has Type of Slat Angle Control for Blinds = FixedSlatAngle, then this is the fixed value of the slat angle; If WindowShadingControl referencing the window that incorporates this blind has Type of Slat Angle Control for Blinds = BlockBeamSolar, then this is the slat angle when slat angle control is not in effect (e.g., when there is no beam solar on the blind); Not used if WindowShadingControl referencing the window that incorporates this blind has Type of Slat Angle Control for Blinds = ScheduledSlatAngle.
