■ Press and hold down the button (3a) and (3b).
The blind/shutter remains stopped, but continues to move after 4 seconds.
■ As soon as the blind/shutter has reached the lower end position, release the buttons and
press button (3b) within the next 4 seconds.
The running time is saved. The blind/shutter moves back to the upper end position.

Saving the ventilation position

To save the ventilation position, the Venetian blind must be moved to the upper end position and the status LED (6) switch off automatically.

■ From the top end position, press the button (3b) for longer than second.

The blind/shutter moves in the lower end position direction.

■ Press and hold down the button (3a) and (3b).

The blind/shutter remains stopped, but continues to move after 4 seconds.

■ As soon as the desired ventilation position has been reached, release the buttons and

press the button (3a) within the next 4 seconds.

The ventilation position is saved. The blind/shutter moves back to the upper end position.

i If the ventilation position is saved again, the old value is overwritten.

6 Operation of lighting

All settings and operations are also possible via Bluetooth app.

Switching the light

■ Press button (3a) or (3b) for less than 0.4 seconds.

i With a dimming insert, the light switches to the brightness that was last set or a saved brightness.

Adjustable parameters via app

Depending on the insert, the following parameters can be changed with the Bluetooth app.

Settings for switching/dimming and Venetian blind inserts

Parameters Setting	optionsDefault setting	Explanations
Position Determination of the current position via the GPS function of the mobile end device.		To adapt the Astro times to the geographical location, the GPS function of the mobile end device must be activated. The Astro time is calculated once a week for the localised place.
Sunrise time offset	+/- 0 ... 120 minutesDefault setting: 0 minutes	Astro times represent the sunrise and sunset times in the course of a calendar year. If you want the switching to be executed in the early morning at the start of twilight or only at full brightness, this can be realised with this shift.An extended adjustment can be used to specify a time at which the switching should be executed at the earliest or at the latest.
