Local sun protection

The application functions can vary depending on the use and technical equipment of a room.

In the TF8040 sun protection templates, one or more groups of external venetian blinds or blinds are assumed.

The templates of the sun protection functions always refer to a group of blinds which are controlled in parallel. Function blocks for the integration of roller shutters are also available.

All room-related sun protection functions are located in the template FB_BA_SunblindZone.

The room functions for a blind group are:

• Sun protection with lamella setpoint tracing
  Sun protection primarily serves as glare protection. The position of the slats is cyclically adjusted to the current position of the sun. As a result, every room is supplied with the best possible daylight despite the prevention of direct sunlight. The energy consumption for the artificial illumination of a room is kept as low as possible. The sun protection also prevents the room from overheating due to solar radiation, thus reducing the energy required for cooling. The sun protection is activated when someone is present in the room.
• Thermal automatic
  With the help of thermal automatic, the sun protection is used in unoccupied rooms to support heating or cooling by selectively allowing or blocking solar heat input. This prevents overheating in summer and reduces the load on the heating system in winter. The thermal automatic processes the room temperature and room temperature setpoint sensor function.
• Twilight automatic
  The twilight automatic function can be used to position sun protection devices depending on the outdoor brightness. This function allows, for example, the sun protection to be closed during the night, e.g. to reduce cooling through the windows or to reduce the building's light emissions and prevent unwanted views into the building from outside.
• Manual control
  The automatic functions of the sun protection system can be manually overridden using a push button, a room control unit that can be integrated via fieldbus, or a graphical control panel via TwinCAT 3 HMI.
