6. USING THIS UNIT
This balanced ventilation unit is designed to provide fresh air to your home while exhausting stale, humid air. Thanks to its energy/heat
recovery module, the unit recovers a large proportion of heat or energy that is part of indoor or outdoor air according to the seasons to
improve comfort and energy effi ciency during the heating and the cooling periods. With the Virtuo Air Technology
TM
, this unit responds
to the variations in its environment in an autonomous way, ensuring to provide a proper level of ventilation and air quality. This unit also
features automatic modes (AUTO or SMART) that manage autonomously the required ventilation level as per indoor and/or outdoor
conditions. In colder areas, the unit will perform, at intervals, recovery module discreet defrost to maintain performance and comfort.
