Connection with Potentiometer (Fig. 7)
Operation
The device operates continuously and allows two different ventilation speeds on two motorised fans in series.
Device operation allows radon to be extracted from rooms, especially those underground or in contact with the
ground, the main source of gas emission.
All device functions can be controlled by an optional wired remote control panel with an LCD display designed
for wall installation and enclosed in a lockable box (Sicurbox: see the relative instructions manual).
