Memory of direction applies both to local and central
control. For example, if the controller carries out a
�������-��
command, then the next press of a local
button will move the roller blind down.
Memory of direction is not retained after a power fa-
ilure.
������� �������
The controller always works with two central control inputs.
Central control allows the roller blinds to move only in the de-
sired direction. Roller blind will stop only after a preset time or
by pressing any of the local control buttons.
If during the execution of one center control command another
one is issued with the instruction to move in the opposite direc-
tion, the roller blind will stop at first and after 1.5 s will then start
to move in the opposite direction. Time of roller blind activation
can be randomly delayed in the control center (up to 1 s) – to
minimize the current surge in the grid in case of simultaneous
activation of multiple controllers.
