Air connection
The regulators for bathroom intakes
blanking plugs are fitted by pressing them onto the
fan casing and they are interchangeable. It is possible
to identify the two different regulator valves of the
regulators (15 m

These ducts must run as straight as possible, with a
a minimum length of 1.5 m of ducts for each extract.

Configuration
According to dimensions of the room to ventilate, the
installer can chose between two different configura-
tions:
1)Vmed+Vmax factory settings), for big flats, i.e kit-
chen+3 bathrooms
2)Vmin+Vmax, for small flats, i.e. kitchen+2 bathroom
Make the cabling according to the following schema-
tics:
Sensor adjustment: the device has two sensors
installed on the kitchen vent (the one with diameter
125 mm) and on one of the 5 vents with diameter 80
mm. The relative humidity threshold value, above
which the device will automatically switch to Vmax,
can be adjusted. The value can be set between 60%
and 90%: to do so, remove the blanking plug (fig.14),
insert a screwdriver and turn the trimmer, following the
instructions, up to the value of the set level.

Use
The device operates continuously. If the set humidity
threshold is exceeded during normal machine
operation at Vmin Config. 2) or at Vmed config. 1,
factory setting), the appliance will automatically switch
to Vmax after approximately 1 minute. The machine will
automatically return to the previous speed once the
5
relative humidity level has been restored back below
the set threshold.
The user can also utilise the external switch to force
29
device operation to Vmax. In this case, the sensors
will be deactivated until the user's subsequent reset of
the previous speed.
