Ventilation Unit - etp OTUS Notice D'installation

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.
FUNCTIONA-
LITY
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.
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 120 seconds, then it
varies automatically according to the detected temperature condi-
tions.
Optimisation of the thermal efficiency. The inversion time is fixed at
Efficiency
about 70 seconds.
Continuous running speed
Speed 1: 20m³/h
Speed 2: 30m³/h
Speed 3: 40m³/h
Speed 4: 50m³/h
Speed 5: 60m³/h
Off position
Pressing the
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
of the LCD display the
