"A-Control" interactivity between indoor and outdoor units en-
ables the system's self-diagnostic function to be used for exam-
ining the entire system; even abnormalities in the outdoor unit
will be shown on the remote controller display. Imporvements in
display details make more accurate and timely responses for
maintenance and repair possible.
The Lossnay ventilation system can be easily connected to and
controlled by the interactive "A-Control" system using an adapter.
The combined interlocking system offers the ability to remove un-
clean air from indoor environments while adding 25% savings in
operating costs for ventilation compared to conventional systems.
Independent control of the Lossnay is also possible.
"A-Control" technology offers compatibility so that systems of the
series can operate as part of the MELANS building air condition-
ing management system. Once connected by a special adapter
(optional), the systems respond to commands given from the
MELANS control center. The remote controller can also be
used for general system control.

Interactive system management, incorporated using an original
technology we call "A-Control," is provided by a single 3-wire
power/control cable connecting system components. In addition,
a non-polarized, dual core wire employed for the remote control
line further facilitates installation work.
Remote Controllers can now be used for the selection and set-
ting of functions such as fan speed, air outlets, etc. which were
previously set from the indoor unit base board.
Setting changes can also be made very easily at the installation
stage.
Thanks to the employment of "A-Control", the remote controller
can be installed up to two sets per system. This greatly upgrades
operability in residential and commercial application.
