If an external device is
connected the “On/Off”
function of this device will
also control the Lossnay
operation.
• If 2 remote controllers are used, the last
controller to be used has priority. (Last
Command)
• If you would like to turn ON the Lossnay
alone while the external device is OFF,
operate it by the Lossnay remote controller.
• The fan speed is on “High”.
• The ventilation mode is “Ventilation Mode
Auto Select”.
2. For connection of a Mitsubishi Electric
Air-Conditioner Network System
(MELANS) or City Multi.

■ LOSSNAY VENTILATE setting
Both fresh air supply and return air pass through the Lossnay core(s).
Resulting in full heat exchange. Lossnay ventilate setting is used for
cooling in the summer and heating in the winter period.

Operation (Continued)
English
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.
Maintenance
Remove all dust and dirt on air filters and Lossnay core(s) at regular
intervals in order to prevent a deterioration in the Lossnay functions.
Guideline: Clean the air filters once a year.
