Default: no time set
NOTE: Before carrying out this procedure programme a remote control (see paragraph 5)
Also check that the motor stops when it gets to the limit and the letter “L” appears on the display (the limit is detected if
there is a mechanical stop or where there is a built-in limit switch).
If that does not occur, adjust the movement threshold with the VR1 trimmer “Sens.” (the trimmer adjusted full scale to “-”
disables the movement threshold).
To obtain non-manual operation via radio set the operation to automatic, Venetian or Open-Stop-Close (see paragraph
3.1).

completed the control unit will beep 4 times in conrmation.
PROCEDURE:
STEP 1
Keep pressing and releasing the SEL key until the
«Wind (Vento)» LED comes on.
The display shows the current setting.
STEP 2
Press and release the SET button to conrm.
The LED on the display ashes.

ALARM NOT PRESENT/END OF ALARM: the temperature detected is above 3°C or no rain is detected.
ALARM TEST: the control unit makes a brief opening movement followed by a brief closing movement. When the test is
completed the control unit will beep 4 times in conrmation.
PROCEDURE:
STEP 1
Keep pressing and releasing the SEL key until the
«Snow (Neve)» LED comes on.
The display shows the current setting.
STEP 2
Press and release the SET button to conrm.
