dusk control described above in more detail. The graphic below explains how the<br />

outdoor brightness can change during the course of the dawn/dusk by means of<br />

Course of brightness and movement behavior<br />

The thick black curve represents the course of brightness. The two horizontal<br />

lines are the limits specified by you for moving the sunblind up or down.<br />

During dawn the outdoor brightness increases until Point 1 of the curve is<br />

reached. Here the limit "Dawn UP" is reached and then exceeded. The delay<br />

period of 5 minutes (which cannot be changed) now begins to run. At Point 2 of<br />

the curve this period has expired and the limit is still exceeded - the sunblind now<br />

moves up.<br />

During dusk the outdoor brightness decreases until Point 3 of the curve is<br />

reached. Here the limit "Dusk DOWN" is reached, after which the brightness<br />

drops below the limit. The delay period of 5 minutes (which cannot be changed)<br />

now begins to run. At Point 4 of the curve this period has expired and the<br />

brightness still lies below the limit - the sunblind now moves down.<br />

6.2.6 The dawn/dusk control<br />

during wind,- rain- or ice<br />

alert<br />

The dawn/dusk control is inactive during a wind,- rain- or ice alert. After the alert<br />

has been canceled, the dawn/dusk control becomes active again and starts again<br />

with the brightness evaluation.<br />
