21. Automatic solar function, brief description
The automatic solar function (solar mode
[ 1 ]
) enables brightness-de-
pendent control of your roller shutter. To do this, a local light sensor is
secured to the window with a suction cap and then plugged into the
Troll Comfort DuoFern device.
If you use external sun sensors (e.g. the DuoFern Sun Sensor or the
DuoFern Environmental Sensor in conjunction with the HomePilot®)
or the Troll Comfort DuoFern itself as a central sun controller for other
DuoFern devices, please read further on page 116.
Automatic solar function

The roller shutter end position can be freely selected by changing the

Please note the state of the sun symbol on the standard display
When the automated solar function is active, the
sun symbol flashes on the standard displays as
soon as the configured set limit is exceeded.
