Blind actuators (Fig. 43)
Blind actuators receive the control commands from sen-
sors and then switch their switching outputs.
If the blind actuator is linked with a sensor, the blind can
be moved with a long press of the button, and the slats
adjusted with a brief press of the button.
Wind alarm
As soon as a wind sensor is configured in the system (for
description of function see page 50), all blind actuators
are coupled to its output signal. This means that during a
wind alarm all roller blinds/awnings and blinds move to
their top end position and are locked. They can then no
longer be moved manually via the control elements. A
flashing LED on the control element signals that the blind
is locked.
All actuators which are not to respond to the wind alarm
can be deactivated via the user interface.
Position fixing/calibrating
Aside from the top/bottom end positions, a blind can also
move to intermediate positions, e.g. 50% top. The position
is fixed on the basis of the movement time of the blind.
Since this movement time varies individually, it must be
fixed separately for each blind.
If nothing has been programmed, the visualization cannot
display an actual position and only the top/bottom end
points can be moved to. The movement time can be set in
the device settings of the user interface.
The LED of a sensor, which is connected with a non-
calibrated blind, flashes at the point of delivery until the
calibration has been carried out.
Heating actuators (Fig. 44)
Heating actuators are suitable for the activation of ther-
moelectric servo valves. They can only be controlled by
room temperature controllers. 3 servo valves share one
input voltage terminal. The current via this common termi-
nal must not exceed In=0.5 A.
