When" Automatic Mode" is enabled, fan speed is
controlled by an automatic control cycle relative to
internal instantaneous humidity and CO2 variations.
• AUTOMATIC MODE
WITH HUMIDITY SENSOR
The fan speed is set according to the interval relating to
the ambient relative humidity detected by the sensor.
If the ambient humidity is compatible with the
ambient comfort (typically between 25% and 50%),
then a special control for air exchange is not necessary
and the user can control the speed of the fans as in
Manual Mode.
If the ambient humidity temporarily goes beyond the
ambient comfort range, then an automatic variable
flow control mode is engaged, for tracking an ambient
humidity target value.
The target value is continuously calculated by the
system as a daily average of the ambient humidity.
This way the system reacts automatically to restore as
much as possible the comfort conditions lost due to an
extraordinary event, such as steam production caused
by a hot shower or a pot while cooking.
In automatic variable flow control mode, the user can
manually change the speed of the fans as required at
any time. The automatic mode will be restored at the
next significant ambient humidity variation.
