Smart humidity control
When the humidity sensor detects a quick
variation of the Relative Humidity level, the
running speed automatically increases to the
next higher speed. After 10 minutes from the
last quick RH variation, the unit returns running
at the selected speed. The smart humidity
control is active if the airflow direction is set on
alternate or extract only: if speed 5 has been
selected, no speed increase happens. To disable
this functionality, press the button for 5
seconds: on the top side of the LCD display the
symbol is shown.

Antifrost
This functionality prevents frost building up on

Acoustic signal
Any time a setting is transferred from the
controller to the unit, a short acoustic signal
is emitted. This can be deactivated by pressing
the

button for 7 seconds, after when a
green led flashes to indicate that the acoustic
signal is off. To reactivate the acoustic signal
repeat the same operation for 7 seconds until
the led becomes green and an acoustic signal
is emitted.
