Central glare protection (CenGlrPrt11)
Overview
The application function "Central anti-glare protection 11" (CenGlrPrt11) calculates the anti-glare protection state using threshold values and time delays, and distributes them to subordinate AFs CenGlrPrt11 or directly to the connected shading functions.
Note: Local anti-glare protection is active if one room is occupied (default value in RShdCoo11 for room operating mode Comfort and Pre-Comfort).

Function
The input is the effective brightness (BrgtEff) from CenBrgtWths11 or CenBrgtFcd11.
The AF calculates the anti-glare protection state forwarded via internal connection. It can accept the following value:
- High
If the sun reaches the facade and the brightness is greater than BrgtLmOn, or if the sun does not reach the facade and brightness is greater than BrgtIdirLmOn for longer than DlyOnBrgt.
Shading moves to the locally configured "High" position (default value: Close and position slats against the sun). - Hold
If the sun reaches the facade and the brightness is less than BrgtLmOff, or if the sun does not reach the facade and is brightness is less BrgtIdirLmOff for longer than DlyOnBrgt.
Shading goes to the locally configured "Hold" position (default: Hold height and open slats). - None
If the sun reaches the facade and the brightness is less than BrgtLmOff, or if the sun does not reach the facade and is brightness is less BrgtIdirLmOff for longer than 4 * DlyOffBrgt.
Shading goes to the locally configured "None" position (default value: Move up). - Dark
If brightness is less than BrgtDarkLmOn for longer than DlyOnBrgt. Dark is reset to None, if brightness is greater than BrgtDarkLmOff for longer than DlyOnBrgt.
Shd11 does not use them, but it is available for customized functional extensions.
The delay (DlyOnBrgt) prevents movements that are too frequent.
The reaction time can be extended on a sliding scale (as a type of integral function) if multiple quick changes occur. Parameters LgtSnsDlyMax and LgtSnsDlyMin are used to this end.
