The outdoor brightness increases until point
a
of the curve is reached; the
“SUN” limit value is reached at that point. Although the "SUN" delay now be-
gins running, your sun shading product is not lowered yet. At point
b
of the
curve, the brightness drops below the “SUN” limit value once more before
the “SUN” delay time has elapsed. Your sun shading product stays up.
The brightness level increases later on and at point
c
exceeds the "SUN"
limit value again. Although the "SUN" delay now begins running, the sun
shading product is not lowered yet. The “SUN” delay time has elapsed at
Point
d
and the limit value is still exceeded - the sun shading product is now
lowered.
A cloud now moves in front of the sun and it gradually becomes too dark in
your rooms; the limit value “CLOUD” is undercut at Point
d
. Nothing hap-
pens initially because the “CLOUD” delay is started first - the sun shading
product is therefore not raised yet. The “UP” delay has finally elapsed at
Point
d
and the limit value “UP” is still undercut; the sun shading product is
now raised again.
Thus, when your delay times are set correctly, they enable the sun shading
product to be controlled in a manner that provides a high level of comfort.
They “quiet” the response of the control. As a consequence, the sun shading
product is not moved immediately whenever there is a change in the outdoor
brightness.
NOTE It also becomes apparent from the graphic that the limit value "SUN" must
always be set above the limit value "CLOUD" or the sun control will not work.
7.2.1.19 The sun control during a
wind, precipitation or ice
alarm
The sun control is not effective during a wind, precipitation or ice alarm. After
the alarm has been cancelled, the automatic sun control becomes active
again and resumes evaluating the brightness.
