Bypass Function

The Vent-Axia Econiq units feature an advanced 100% summer/night bypass function, ensuring optimal comfort throughout the year. This intelligent function enables the unit to switch to bypass mode during warm summer days or nights when outdoor temperatures are cooler. Heat recovery is then disabled, and cool outdoor air is supplied directly. This provides refreshing, natural ventilation while maintaining a comfortable indoor climate without unnecessary energy use. The 100% summer/night bypass function of the Vent-Axia Econiq guarantees efficient and comfortable ventilation.
