4.0  Operation

 

 

In both versions, the unit extracts air out for 70 seconds, then it supplies air in for the 
same time. When heated air is pulled (extracted) from inside the room, it warms up the 
heat exchanger; when the cold air is pushed (supplied) in the room, it gets preheated, 
recovering  most  of  thermal  energy  which  would  be  otherwise  lost  in  the  ventilation 
process. 

The unit runs at the speed selected by activating the switches “S1”, “S2” and “S3” of the 

Air 

Controller 

(accessory fig. 57). The same functionality can be achieved with 

Air Controller 

or with 3 switches. 

 

 

 

 

S3  switch  activates  the  “Free  cooling“  (Bypass)  mode,  which  stops  alternate  flow  and 
keeps the fan in “extract

-

only” or “intake

-

only” mode, to avoid the heat exchange when 

necessary. To set the 

extract-

only” mode or “intake

-

only”, place the integral jumpe

rs as 

per fig. 20A

-20B. The front cover LED indicates when the Free cooling mode is on. 

An automatic “Boost”mode can be achieved through a dedicated switch or room sensors 

like humidity sensor, CO2 sensor, PIR sensor, connecting such switch in parallel to the S2 
switch. 
 

Wiring diagram of one unit: fig. 18A.

 

Wiring diagram with ambient sensors: fig.18B

-18C.  

Wiring diagram of two or more units: fig. 18D.

 

 

WARNING

Ensure that the electric wiring to L and N is done correctly; an incorrect connection will 
lead to malfunction or permanent damage of the fan. 
 

4.1  Synchronisation 

When the units are installed in pair, they must be synchronised so that when one unit is 

extracting, the other is supplying, and viceversa (fig. 18E

-18F-18G). This is achieved by 

setting th

e dedicated jumper (fig. 20A

-20B). 

 
RESET OF THE SYNCHRONISATION 

OPTION 1

: If two or more units are connected under the same main switch, to reset the 

synchronisation, the main switch must be switched first OFF and then ON to reactivate 
(fig. 31).
