Possible cause / solution
... the RolloTron Comfort DuoFern indicates no functions? Check the power supply incl. connecting cable and plug.
... the RolloTron Comfort DuoFern no longer reacts in the
morning at the configured switching time?
The electronic system switched off the drive after closing the roller
shutters because the deflection roller stopped turning. This is the case if:
a) The [ Down ] button was pressed for an excessive period of time
during the configuration process for the lower end point. The roller
shutter slats are closed, but the belt continued to wind and is no
longer tight on the deflection roller.
b) The lower end point is displaced due to elongation of the belt.
The belt may never be slack.
Reconfigure the lower end point (see page 64) and ensure that
the belt remains tight to the deflection roller.
In doing so, the deflection roller must turn evenly.
... the roller shutters no longer stop at the configured end
points?
The end points may be displaced due to elongation of the belt.
Readjust the end points, see page 64.
... the roller shutters stop as soon as the control key is
released?
The end points are not configured. Configure the end points, see
... the RolloTron rotates in the wrong direction?
Possibly the belt is wrapped around the reel incorrectly, see page 21.
