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.
Functionality Description
The unit runs in extract/intake at the selected speed: the
Alternate
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.
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.
Optimisation of the thermal efficiency. The inversion time is

Pressing the — button for 3 seconds, the units. switches off,
emitting a long acoustic signal. To re-activate the unit, press
any button.
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.
The unit runs in "extract only" or "intake only" to avoid heat
recovery when not needed.
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.
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
seconds: on the top side of the LCD display the symbol• is
shown.
