What is the LOSSNAY HEAT RECOVERY VENTILATOR...?
Effective ventilation routes can be achieved in the entire house by the supply air vent and the exhaust vent
being installed at locations away from each other depending on the duct connection method.
Built-in filters reduce the influx of dust, pollen, etc, in outdoor air before the air is supplied to rooms.
Heat exchange operation
Dirty air from the room is discharged (=exhaust), and clean air from the outdoor is taken into the room (=air supply).
During this time, air is discharged and taken in through the Heat exchanger. As a result, air is ventilated while
reusing (heat collection) the warmth or coolness of the room which is discarded during ventilation.
When air conditioning is used in summer and winter, heat exchange ventilation reduces the load placed on air
conditioning to ensure energy savings.
Bypass operation
When exhaust and air supply are performed, air is supplied to the room without any change in the outdoor air
temperature due to exhaust being performed without passing through the Heat exchanger.
In spring and fall, and summer nights, for example, the cool air of the outdoor is taken in.

Note
- Ventilation is conducted at the ventilation air volume (Base Notch) required for the residence.
- By setting to Boost/Purge, the ventilation air volume is increased temporary to quickly ventilate the air.
- In the long absence, use the Holiday mode to save energy by reducing the fan output.
