The radio-capable time switch for roller shutters Discover our Troll Comfort DuoFern - the
radio-capable time switch for roller shutters. Connected to an electric roller shutter drive
the Troll Comfort DuoFern controls and provides automation for your roller shutters. Thanks to
the integrated radio interface your roller shutters are also remotely controllable at the same
time. With its modern design large illuminated display the piano lacquer finish and intuitive
5-way navigation this radio time switch is a real eye-catcher! In addition to the extensive
automatic functions such as the day week astro programme or random function the Troll
Comfort DuoFern also provides easy installation assistance. This guides you through the initial

switching times. The switchover of the roller shutter time switch from summer to winter time is
effected fully automatically. Moreover the radio-capable time switch also has integrated
blockage detection for mechanical tubular motors - this protects frozen roller shutters against
damage. Furthermore sun dusk control is possible with the sun and dusk sensor that is

aluminium finish. The time switch can be integrated into any standard switch range using an
intermediate frame thanks to the design according to DIN 49075.
