D-D Mode (Dusk to Dawn)
The lighting switches on at dusk as soon as the ambient light is below the preset lux value. The lighting will
remain on until the next morning and automatically turn off when the ambient light is above the preset lux value.
I.T. Mode (Intelligent Twilight)
The lighting switches on at dusk as soon as the ambient light is below the preset lux value and will remain
on for a default of 4 hours before switching off. During the morning the lighting will turn on < 2 hours prior
to dawn to ensure a safe illumination of your surroundings. The I.T. mode will learn from the changes of
daylight hours in different seasons and weather conditions.
(Teach-in Mode)
Switch the lux adjustment to
lighting to automatically turn on. After this setting, immediately attach the front cover and step away to
avoid interference with the ambient brightness measurement of the twilight switch. The lighting will switch
off and the LED indicator will flash for 20 sec when the twilight switch is memorizing the ambient brightness.
Afterward, the LED indicator and the lighting will stay on for 3 sec and then go off. The teach-in process is
complete. The memorized brightness value is accepted as the new threshold switching value.
