Global sun protection

In addition to the local sun protection functions, there are other application functions in the system from which global positioning commands are sent to the sun protection actuators.

The following sun protection functions are located in the building level of the shell model.

The functions are implemented in the template FB_BA_BuildingSunprotection.

• Fire
  In the event of a fire, all the blinds in a building are raised.
• Storm protection
  The storm protection function prevents external sun protection devices from being damaged by wind.
• Icing protection
  The risk of the blinds icing up is predicted by combining the measured values for outside temperature and precipitation. To protect the blinds from mechanical damage, they move up when there is a risk of icing and remain there until a predicted icing time has elapsed.

There is one instance of the template FB_BA_Facade for each facade of the building.

The template contains functions and calculations related to a facade.

• Maintenance
  To check that all the blinds on a facade are fully functional and correctly positioned, it is possible to raise and lower all the blinds on a facade synchronously using the maintenance function. In the case of facade cleaning, the blinds of a facade can all be raised and blocked in this position.
• Global thermal automatic
  The global thermal automatic has the same function as the local thermal automatic within the rooms. However, it controls all the blinds on a facade in the same way, so that a uniform image of all the blinds on a facade is created during longer periods of absence, e.g. at weekends. The global thermal automatic uses the measured room temperature value of a reference room.
• Communication error
  In the event of communication problems within the BA network, it is not ensured that the positioning telegrams are passed through to the sun protection actuators with a high priority. The blinds are then raised for safety reasons.
