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 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. Once the weekly timer has been set, no switching
on-off is required.
