8.4. Modifying the angular travel

For optimum operation of the J4 io actuator, it is

essential to adjust the angular travel.

The angular travel is the total angle necessary for the

blind to change from a slats closed position to a slats

fully open position.

The slats fully open position is reached when the slats no

longer tilt and the blind makes an initial raising movement.

• Press the down button until the lowered position is reached.

• When the blind is in the lowered position, press the up and

Down buttons for 5 seconds: the blind moves briefly.

• Press the "my" button on the control point: the blind moves

briefly.

• Move the slats from the slats closed position to the slats fully

open position by briefly pressing the up button on the control

point.

• Press the up and "my" buttons on the control point at the

same time, until the blind moves.
