The adjustment knob allows you to change the time of the
air intake / extraction cycle from a minimum of 35 sec to a
maximum of 200 sec. as a function of the temperature
difference between the outside and the inside.
If the difference in temperature between inside and
outside is high, to ensure thermal efficiency, the cycle time
must be as short as possible. If, on the other hand, the
temperature difference is close to zero, the cycle must last
as long as possible.
For example if in winter the outside temperature is
–5 ° C and therefore the temperature difference between
inside and outside is high, turn the knob to the position
with the most marked DT line. Unlike on a spring day,
where the temperature difference is minimal or close to
zero, turn the knob to the position with the thinnest DT
line; below are four reference values.

OPERATION OF THE CONTROL UNIT - VERSION E -
The control unit consists of ten buttons which contain all
the product functions inside them.
The central LED, between the on-off keys and the info key,
allows you to view when a function key is pressed, the
sending of the command to the fan unit.
Above some buttons, there are signaling LEDs which, by
requesting information to the fan unit, will indicate the
operating status.
