12.2.1 User present
When the user is detected the sash can be moved in the following ways:
Manually
When the Tiptronic feature is enabled the sash can be manually
moved, when it is kept moving for more than 1 second.
Note: This is the minimum time for which the sash must travel
to be operated manually. Movement for less than the
specified time will lead to the sash auto-driving to the
appropriate calibrated position.
Tiptronic
When the sash is manually moved for less than 1 second the
sash will auto-drive to its calibrated position.
↑ / ↓ pushbuttons
When pressed, the sash will auto drive to its calibrated position.
Footswitch (open and
close options) (optional)
When operated, the sash will auto drive to its calibrated
position.
12.2.2 User not detected
When the user is not detected, the sash will auto close to its calibrated position following a pre-
set delay time unless:
• The sash beam is broken - object detected in the sash opening.
• The controller does not detect sash movement when the motor is driving.
12.2.3 Auto-open
Auto-Open is a user configurable process. When enabled, the sash automatically opens when
the user returns following a pre-set delay.
• If the sash is auto-closed, the sash will automatically open back to the same position the
sash was in before it automatically closed.
• If the sash is closed by any other method, for example manually, tiptronically, pushbutton
and BMS, the sash will open automatically and return to its calibrated position.
The sash will not open automatically if:
• The sash beam is broken - object detected in the sash opening.
• The controller does not detect sash movement when the motor is driving.
