Important information on: Operating modes and functions
Sunrise, sunset, shading
A brightness sensor controls the position of shutters or awnings
within a specified time window (e.g. from switching time sunrise
to switch time shading), regardless of the measured brightness
level.
The functions sunrise, sunset and sun protection are activated
manually, via time programs or lifestyles and are controlled by 3
values:
•
Brightness value
•
Switching time
•
Setpoint position
The response time of the shutters can be delayed (see "Setting
response delay of shutters" on Page 80).
The sun protection function can also be controlled by the outside
or inside temperature (see "Sun protection function (SP)" on
Page 14).
Sunrise function (SR)
Shutters are moved to the setpoint position when the switching
time and brightness value are reached.
Example:
Shutters are opened up to 80 % in the morning starting at
7.00 a.m. if 30 % of the brightness value is reached.
The shutters remain closed if the brightness value is not reached.
They are opened to 80 % when the brightness level is reached. If
the shutters are already above the setpoint (e.g. due to manual
setting to 90 % on the previous evening), they are not moved.
Sunset function (SS)
Shutters are moved to the setpoint position when the switching
time and brightness value are reached. If the shutters are al-
ready below the setpoint position, they are not moved.
