ADVANTAGES
Clean air supply, dirty air exhaust by Two air paths (OA SA and RA EA)
Energy recovery by LOSSNAY Core
Free cooling by bypass damper
MULTI VENTILATION MODE for multi ventilation request (Power supply, Power supply/exhaust, Power exhaust)
• Without ventilation...
Lack of Ventilation makes people sick by dirty indoor air including CO
2
, Dust, Bacteria.
• If just opening windows...
Opening windows eliminates dirty air BUT wastes much air-con energy.
• So we recommend LOSSNAY
LOSSNAY is simultaneous pursuit of Ventilation and Energy Saving.
EA (exhaust air)
OA (outside air)
SA (supply air)
RA (return air)
• This is LOSSNAY !

In addition to the conventional Extra High, High, and Low
modes, an Extra Low mode is added to provide a more
dynamic range of air volume settings and versatility in a
variety of installation environments, yielding much better
energy conservation. Using a simplified timer function, it
switches to Extra Low operation when the operation stop
button is activated and it is accordingly possible to
implement 24-hour energy conservation ventilation.
Additional energy conservation by using a
four-level air volume system that allows
more precise control.
Extra Low Mode
* The Extra High and High ventilation modes are selectable by the initial
setting.
* Extra-Low not equipped LGH-150RX
5 and 200RX5.
* The ventilation mode is actually selected in three levels, and the remote
controller also displays these three levels.

Air volume level can be set hourly (max 8 times) and weekly. You can pre-set air volume according to the predictable
requirement so that LOSSNAY can automatically operate at only necessary air-speed at the specified time period, which
saves power consumption while maintaining the indoor air quality. Besides, once the weekly timer has been set, no
switching on-off is required.
