Mitsubishi's newly developed Hyper Eco Element is on
board, offering the industry's best total heat exchange
efficiency. Energy conservation performance has been
improved not only by reducing the air conditioning load
associated with ventilation, but also by facilitating humidity
penetration.
Introducing the new Hyper Eco Element
Better energy conservation by improved total heat exchange efficiency.
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
In addition to the automatic damper open/close
function, open/close control via external devices
is now possible, delivering a By-pass
ventilation system that is suitable to the installed
environment.

* When the outdoor air tempereture drops lower than 8ºC it changes to the heat exchange
ventilation. (Display of the remote controller does not change)
* In 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.
* The Extra High and High ventilation modes are selectable by the initial
setting.

* The ventilation mode is actually selected in three levels, and the remote
controller also displays these three levels.

Automatic 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.

When SW1 is "ON", fan speed of the LOSSNAY will be set
to "High"(Extra-High) regardless of the remote control setting.
Use this in such a way that it ventilates at Low or Extra-Low
fan speed normally, and when the external sensor detects
contamination of indoor air, it changes to High (Extra High)
fan speed operation.
To force High fan speed externally
Air volume can be set using a pin position.

changed to the By-pass ventilation regardless of the
setting on the remote controller.

The system allows you to measure

amount of fresh air supplied. By
connecting a CO

sensor to the
connector CN16, which is added to
the LOSSNAY main unit, the setting
can be switched to High, Low, or Extra Low
operation, which is selected when the sensor is
turned ON. This system produces additional energy
conservation.
