Automatic dusk function with Astro pro-
gramme
The twilight time is recal-
culated every day based on
the geographical loca-
tion 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.

or in the event of a manual
command.
