The device ombra BST is a LON
automat for sun position dependent
tracking of blind slats. A maximum of
15 facade segments can be - depending
on the direction or height of the
building - can be controlled
independently.
The automatic slat automat can be
used with all spega e.control blind
actuators. A brightness sensor (e.g.
ombra W2, Order No. 411 202 C) is
required on each side of the facade to
activate the glare protection.
The automatic system determines the position of the sun (azimuth and elevation) for
each facade segment depending on the time of day and adjusts the length and angle of
the blinds in an adjustable cycle as long as the external brightness exceeds the limit
value for the glare protection. In this way, the automatic system ensures maximum
daylight without causing glare.
The automatic system can be activated or deactivated by the operator, either manually
or by a timer. User access can still be restricted by password.
A powerful plug-in is available for the device.
Specialist knowledge of LonWorks® technology is required for project planning, design
and commissioning of the device.
