6.1.10 Using the sun control
correctly
Control Unit EWFS ® The following section describes the effects of the setting values for the sun control
described above in more detail. The graphic below explains how the outdoor
brightness can change during the course of a certain period by means of an
example diagram:

Fig. 6-4: Course of brightness and movement behavior
The thick black curve represents the course of brightness. The two horizontal
lines are the limits specified by you for moving the sun protection up or down.
The vertical dashed lines mark the delay periods for activating and de-activating.
Let us assume that you have set 2 minutes for this delay period, then the sun
protection reacts as follows:
The outdoor brightness increases until Point 1 of the curve is reached. The
"DOWN" limit is reached here. The "DOWN" delay period now begins but your sun
protection is not yet moved down. The brightness drops below the "DOWN" limit
at Point 2 of the curve before the "DOWN" delay period has expired. Your sun
protection has remained at the top position.
Later on the brightness increases again and exceeds the "DOWN" limit once more
at Point 3. The "DOWN" delay period now begins to run again so that your sun
protection is not yet moved down. However, the "DOWN" delay period has already
expired at Point 4 and the limit is still exceeded - the sun protection now moves
down.
Now a cloud moves in front of the sun and your rooms slowly become too dark.
The limit "UP" is dropped at point 5. Nothing happens yet, because the "UP" delay
period now first starts - the sun protection therefore does not move up yet. The
"UP" delay period has finally expired at Point 6 and the brightness still lies below
the "UP" limit. The sun protection now moves up again.
The correct setting of the delay periods thus results in a comfortable control of
the sun protection. It contributes to "smoothening" the reaction behavior of the
control system. This ensures that the sun protection is not moved immediately
whenever the outside brightness changes.
TIP
The graphic also illustrates clearly that the "DOWN" limit
always has to be set higher than the "UP" limit - otherwise
the sun control does not function.
6.1.11 The sun control during
wind, rain or ice alert
The sun control is inactive during a wind, rain or ice alert. After the alert has been
canceled, the sun control becomes active again and starts again with the
brightness evaluation.
