18.6 Automatic dusk function; brief description

automatically to the lower end point or congured ventilation
position.

◆ 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
The twilight time is recalculated every day based on the geo-
graphical location and the current date (dened by the congured
postcode). This means that it is not necessary to continuously
readjust the closing time throughout the year.
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.
A light sensor is not required for this function.
