Operation
Down = ∇:
Pressing it again stops the shutter motion.
Mode of operation L (see also chapter on "Modes of
operation")
Brief actuation (tapping) has the same effect as in "normal
operation". The shutter moves up to the corresponding
limit position.
The long actuation can be used to change the slat angle in
stages:
Up = ∆:
Down = ∇:
Brief actuation (tapping) of the lower
surface
– the shutter is moved into the lower
end position.
Long actuation of the lower surface
– The shutter moves down as long as
the key is pressed.
Long actuation of the upper surface, the
shutter moves up, timed.
Long actuation of the lower surface, the
shutter moves down, timed.
