Blinds Control Routing Entry

Sunlight is an excellent source of lighting, but when the sun is visible through a window, it often causes glare. The commonest way of preventing glare is to use blinds. Among other benefits, blinds can play a vital role for daylight harvesting systems, reduce energy costs for cooling, and avoid the fading of textiles and furniture.

You can create a blinds control routing entry to set the position of the blinds integrated in your lighting system A network of client PCs, routers, control devices, control gear, and lamps if they use:

• a Helvar 490 Blinds Controller;

• a Somfy Sonesse® motor;

• a QMotion Qconnect Q0244 serial bridge; or

• a generic RS485 blinds controller.

A blinds control routing entry provides an intelligent interface between the router system and the blinds controller. For information about how to create a blinds control routing entry, see Create a Blinds Control Routing Entry.

The path of the sun varies every day of the year because of Earth’s tilt and orbit. This variation affects the optimal position of your blinds. So you can take advantage of a Sun Tracking Routing Entry to adjust your blinds to the most suitable scene for your needs at any time and day based on:

• the calculated position of the sun at your location; and

• the amount of light detected by the interior- or exterior-mounted light sensors integrated in your lighting system.

For example, you can recall a blind scene that only blocks out the sun but lets in as much light as possible. Thus, you can minimise glare and maximise daylighting while ensuring that all the movements of the blinds take place in such a way that nobody feels disturbed or distracted. For more information, see Sun Tracking Routing Entry.

Good blind positions

A further advantage of a blinds control routing entry is that it offers the possibility to override a sun tracking routing entry manually. This can be useful when you want the blinds in a different position to the scene that the sun tracking routing entry has recalled based on the position of the sun. For example, by pressing a button you can raise the blinds even though the sun is visible through the window.

The following figure shows how the various data sources can be combined to position the blinds.
