Operation
This Lossnay unit is operated by Remote controller. (provided by installer)
Please refer to installer for further information.
1. Fan speed
nThe wide range of fan speed and the low power consumption
This unit has 5 fan speed settings 110 l/s to 25 l/s, and 14w ultra low power consumption for Lossnay ventilation, thanks of DC blushless motor
technology.
nPower "BY-PASS" mode setting
This unit has 130 l/s extra-high fan speed for "By-pass" ventilation over 5 fan speed.
2. Ventilation setting
nLOSSNAY ENERGY RECOVERY VENTILATE setting
Both fresh air supply and return air pass through the Lossnay cores.
Resulting in total heat exchange. Energy recovery ventilation makes
the fresh air temperature close to the indoor temperature in the winter
and the summer season.
Fresh air
Exhaust air
Supply air
Return air
n"BY-PASS" VENTILATE setting
The fresh air passes through the Lossnay cores and the return room
air is exhausted direct. Energy recovery "By-pass" ventilation is
normally operated during the spring/autumn months.

nAUTOMATIC VENTILATION setting
The automatic damper mode automatically provides the correct ventilation for the conditions in the room. The following shows the effect “By-pass”
ventilation will have under various conditions.
1. Reduces cooling load
If the air outside is cooler than the air inside the building during the cooling season (such as early morning or at night), “By-pass” ventilation will draw
in the cooler outside air and reduce the cooling load on the system.
2. Night purge
“By-pass” ventilation can be used to release hot air from inside the building that has accumulated in buildings a business district during the hot
summer season.
3. Office equipment room cooling
During cold season, fresh air can be drawn in and used as is to cool rooms where the temperature has risen due to the use of office equipment.
lIn the case of “By-pass” ventilation, the supply air temperature slightly rises more than the outside air temperature because of the heat
effect around the ducts or the unit motors.
lOperate by 5 fan speed (Lowest speed) during night time, for low noise level, energy saving and preventing to intake water mist of fog
during night.
lOperate by 5 fan speed in foggy day.
