HUMIDITY AND IAQ DISPLAY
Long pressure (3 sec) of the central fan key allows you to immediately show the humidity
detected.
Pressing the same button again for 3 seconds switches to the IAQ value.
Wait 10 seconds without pressing any key to automatically exit this menu and return to the

MODIFICATION OF FANS SPEED AND BOOSTER FUNCTION
-On the display there are keys for selecting the desired speed of the unit;
Each time the speed is selected, the actual fan speed variation occurs after 1 second.
-There are three selectable speeds:
Night (minimum speed) - nominal (medium speed) - maximum (maximum speed)
The Booster command, which takes priority over any speed, is managed through the digital

NOMINAL SPEED FUNCTION
-By pressing the auto key, the unit will operate according to the humidity and air quality sensor request
setting according to the dipswitch settings made when starting the unit;
If the sensors are set, the logics will be as follows:
- Humidity sensor:
- in winter, the regulation of the flow rate increases according to the increase in humidity;
In this way the ambient humidity is controlled to have the correct humidity in the room;
- in summer the regulation is inverse and the flow rate decreases as the internal humidity increases;
this is because in summer the absolute external humidity contributes to the increase of the internal
relative humidity;
- IAQ air quality sensor:
In both seasons the unit measures the air quality index; This numerical value ranges from 0 (excellent air
quality) to 5 (poor air quality). The sensor ranges are
-
0 to 1.99: Excellent air quality
-
2 to 2.99: Good air quality
-
From 3 to 3.99: Medium air quality; Exposure to these values for more than 12 months is not
recommended
