Multi-ventilation Mode enables the appropriate supply/
exhaust balance to be selected to suit the usage environment and location
Featuring "Multi-ventilation Mode,"
which allows the air supply/exhaust
balance to be varied dynamically.
The supply/exhaust balance can be
selected to suit the usage environment
and location, such as allowing for air
exhausted via extractor fans. Modes can
be selected easily by setting the
connectors on the circuit board.
* "High notch" can also be further set to "Extra High" using the unit switch.
Offers choice of 9 air supply/exhaust combination patterns.

Night Purge Function
Newly Adopted Dot Matrix Display Available in Eight Languages
During the summer season, the Night Purge function draws cooler outside air into the room to suppress temperature
rises at night. This energy conservation function reduces the load when air conditioning is started the next morning.
timer
The out door temperture (OA) setting can be selected either 17゜ C or 28゜ C by using Dip-Switch (SW2-7) in the LOSSNAY control box. Refer to the Instillation Manual for more information.
*Do not use the night purge function if fog and heavy rain is expected. The entry of rain water may occur in the night.
While air conditioning and
ventilation are not operating,
the room temperature rises as
a result of heat from the
skeleton and OA equipment.
When the outside temperature
becomes lower than the room
temperature, ventilation starts
automatically.
The air conditioning load
required to reach the set
temperature the next
morning is reduced.
At night, the outside
temperature drops.
When the room becomes
sufficiently cool, ventilation
is stopped.
Hot air is discharged.

New Remote Controller PZ-60DR-E
A new remote controller for the RX5 series is now available. In addition to boosting the energy conservation performance of
the main unit, the remote controller features a variety of new functions which also pursue additional energy conservation.
The appearance of the remote controller conforms to Mitsubishi air conditioner interface design standards.
Functions that were set using Dip-Switch on the LOSSNAY main unit can now be configured as needed using the new re-
mote controller. This eliminates the need to crawl under the eaves to change operation settings.
Also, a newly adopted dot matrix display provides much more information, making it easy to check maintenance indica-
tions, operation status display, and explanations required when configuring settings.

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.
