VENTILATION UNIT
When switched on the unit emits a long acoustic signal.
Through the IR controller the following functionalities can be activated/deactivated. When one setting is transferred to the unit, a short
acoustic signal is emitted and a green led flashes.

Airflow direction
Alternate
The unit runs in extract/intake at the selected speed: the
inversion time is automatically defined thanks to the integrel
temperature sensor.

Extract
The unit runs in extract only at the selected speed.

Intake
The unit runs in intake only at the selected speed.

Mode (active only if the airflow direction is set on alternate)
Comfort
Optimisation of the acoustic and thermal comfort. The inversion
time varies automatically from 40÷120 seconds, thanks to
the integrel temperature sensor. The first time cycle is of 120
seconds, then it varies automatically according to the detected
temperature conditions.

Efficiency
Optimisation of the thermal efficiency. The inversion time is
fixed at about 70 seconds.

Pressing the button for 3 seconds, the units switches off,
emitting a long acoustic signal. To re-activate the unit, press
any button.

BOOST speed
The unit runs at speed 5 (maximum) for 15 minutes, in extract
only; then it returns to the previously selected mode/speed. The
BOOST speed cannot be activated if the controller is OFF.

Free cooling
The unit runs in “extract only” or “intake only” to avoid heat
recovery when not needed.

Filter reset
Every 3 months a yellow warning led switches on (fixed light)
to indicate that the filters have to be maintained. Press the
dedicated button for 5 seconds to reset the timing.

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.
