Example of time program and astro function for outdoor lighting
You want the outdoor lighting to come on in the mornings and evenings when
the residents leave the house or return home.
The outdoor lighting is switched on from Monday to Friday from 06:00 to 08:30
in the morning and from 17:00 to 22:30 in the evening via a time-switch function.
The astro function ensures that the switching times are adapted according to the
sunrise and sunset.
In winter, the time program switches the lighting on at 06:00 in the morning and
the astro function switches it off after sunrise (e.g. at 08:30). In winter, the sun
sets before the switching time of 17:00 set in the time program, which means
that the sunset is not weighted here and the lighting is not switched on until
17:00. The lighting is switched off at 22:30. During the course of the year, the
sunrise and sunset times change, therefore the switching times also change.
In March, the sun still rises after the set switching time. The lighting is switched
on at 06:00 in the mornings. In the evenings, the sun does not set until after the
switching point of the time program. The lighting therefore remains off and is
only switched on around 19:00 in the evening.
In mid-summer, the sun rises before the programmed switching point. At 05:30,
it is already sufficiently light for the outdoor lighting not to be switched on. The
outdoor lighting therefore also remains switched off in the evenings.
