20. Automatic wind function; brief description

This function enables you to use the Troll Basic DuoFern to operate, for example, connected

Venetian blinds or awnings in relation to the weather conditions. The automatic wind function

can also be switched on/o by an overriding DuoFern controller (e.g. HomePilot®).

As soon as an external "wind" signal transducer is detected, the control signal can be transferred

from the DuoFern network on the Troll Basic DuoFern.

The direction of operation in the event of wind can also be congured by an

overriding DuoFern controller (e.g. HomePilot®).

In the event of windy conditions, the Venetian blinds or awnings can be retracted or a draught

stop closed.

If the automatic wind function is active ...

◆ the timer LED [

] ashes green in a 2 second cycle.

◆ manual operation is no longer possible. automatic movements are no longer executed.

■ the last automatic movement command to be received will be stored and will be

resumed as soon as the wind subsides.

Manual mode and the automatic wind functions are active again:

◆ as soon as a period of 15 minutes has elapsed where no wind command was received

or the registered signal transducer (e.g. DuoFern environmental sensor) deactivates the

automatic wind functions.

NOTE

◆ The automatic wind function is interrupted in the event of power failure.

◆ If the direction of rotation for wind is set to DOWN and wind is detected when the drive

is at the upper end position, then the drive moves back to the upper end position as soon

as no more wind is detected.

Behaviour of the automatic wind function when the automated solar function

is active:

◆ If the automatic wind function is started when the automated solar functions are active,

then the awning moves back to the sunshine position as soon as the automatic wind

function is ended, assuming the automated solar functions are still active.

■ This does not apply if the automatic rain function has activated in the mean time.
