FUNCTIONALITY
Airflow direction
The unit runs in extract/intake at the selected speed: the inversion
Alternate time is automatically defined thanks to the integrel temperature sensor
(comfort mode).
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)
Optimisation of the acoustic and thermal comfort. The inversion time
varies automatically from 40÷120 seconds, thanks to the integrel
Comfort
temperature sensor. The first time cycle is of 70 seconds, then it varies
automatically according to the detected temperature conditions.
Optimisation of the thermal efficiency. The inversion time is fixed at
Efficiency
about 70 seconds.
Continuous running speed
Speed 1: 20m
Speed 2: 30m
Speed 3: 40m
Speed 4: 50m
Speed 5: 60m
Off position
Pressing the button for 3 seconds, the units switches off, emitting a
long acoustic signal. To re-activate the unit, press or .
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.
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 cgfgf
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.
