The Ecocomfort can work with two ventilation units up to a maximum of four. The system is designed to operate in an
alternating way. If for example two units are installed, the first device operates by introducing air from the outside,
while the second device operates by extracting air from the room. When after some time there is the inversion of
the direction of rotation of the fans, the first device extracts the air to the outside while the second device brings the
air into the room. The alternation of operation in torque, ensures that the sum of the air flow emitted is equal to the
sum of the air flow extracted.
