close automatically to the lower end point or configured

◆

Automatic dusk function with Astro programme

◆

Automatic dusk function with light sensor 

= switching time mode [ SENSOR ]

At twilight, the roller shut-

ters will lower to the lower 

end limit or configured 

ventilation position after 

approx. 10 seconds. The 

roller shutters will open 

again once the configured 

opening time is reached 

or in the event of a manual 

command.
The required twilight limit is configurable.

NOTE 
The  automatic  dusk  function  via  light  sensor  is  only 

executed once per day.

The twilight time is recalcu-

lated every day based on the 

geographical  location  and 

the current date (defined by 

the configured postcode). 

Configure a custom offset period
An offset can be configured 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.
