Specifications

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.

"By-pass" operation
New function: "By-pass" Ventilation External Control Setting
* When the outdoor air tempereture drops lower than 8°C 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.
•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.
Establish the wire connection by inserting the optional
remote display adaptor (PAC-SA88HA-E) in the connector
CN16 (Ventilation mode selector).
With SW1 is “ON”, the ventilation mode of LOSSNAY is
changed to the By-pass ventilation regardless of the
setting on the remote controller.

New Remote Controller PZ-60DR-E
A new remote controller for the RX5 series is now available. In addition to boosting the energy conservation perfor-
mance 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 remote controller.
This eliminates the need to crawl
under the eaves to change operation
settings.
Also, a newly adopted dot matrix
display provides much more informa-
tion, making it easy to check mainte-
nance indications, operation status
display, and explanations required
when configuring settings.
