18.3 Automatic dusk function; brief description

The automatic dusk function causes the roller shutters to

close automatically to the lower end point or congured

ventilation position.

You can choose between two automatic dusk

functions:

◆ Automatic dusk function with Astro programme

= switching time mode [ ASTRO ]

◆ Automatic dusk function with light sensor

= switching time mode [ SENSOR ]

Automatic dusk function with Astro

programme

Automatic dusk function with connected

light sensor

At twilight, the roller shut-

ters will lower to the lower

end limit or congured

ventilation position after

approx. 10 seconds. The

roller shutters will open

again once the congured

opening time is reached

or in the event of a manual

command.

The required twilight limit is congurable.

NOTE

The automatic dusk function via light sensor is only

executed once per day.

Mounting the light sensor

(see page 56, Automatic solar function)

The twilight time is recalcu-

lated every day based on the

geographical location and

the current date (dened by

the congured postcode).

Congure a custom oset period

An oset can be congured between -60 and +60 minutes

in order to customise the calculated dusk time to your

personal preferences. This means that it is not necessary to

continuously readjust the closing time throughout the year.

A light sensor is not used for this function.
