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 di-
rection 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 the
heat exchanger due to extremely cold air. When it
is activated, the unit runs in extract only at speed 1,
for 30 minutes.

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 si-
gnal repeat the same operation for 7 seconds until the
led becomes green and an acoustic signal is emitted.
Green Short
Back-Up Button
In case the remote controller gets lost or the batteries are dead,
speed 1,3 and OFF position can be selected from the on board
touch button (C). The airflow direction is always alternate and
the operation mode (either comfort or efficiency) is the last
selected from the remote controller.

*press the button for 3 seconds.
Synchronisation of a number of units
It is possible to synchronized up to 10 units contemporaneously,
through wire (2 pole twisted pair type, max 30m length) so to
have mode and inversion time synchronized. When the unit is
switched on for the first time, the rotation direction of each unit
(clockwise or anti-clockwise) is automatically established. Other
functionalities like speed, smart humidity control and boost,
continue to be controlled independently on each single unit.
