AC SMART II Characteristics
AC Smart is the central controller that can manage maximum of 64 air conditioner indoor units within
one space individually or in integrated manner. AC Smart can monitor or control the operation of the
air conditioner and ventilator installed in each room of the building from one location, such as an
administrative office of the building.
The characteristics of AC Smart are as follows.
Individual and integrated operation & monitoring
AC Smart can control and monitor the following items by selecting the installed air conditioner by
individual unit, by group or all.
• Operating condition of the air conditioner
• Operating mode
• Fan level
• Wind direction
• Lock
• Set temperature
Therefore, the manager can control everything just with AC Smart (Central control) from the
administrative office of the building where the air conditioners are installed.
Group management
AC Smart can manage the installed air conditioners by zone and group. When you use the zone or
group setting, you can classify the air conditioner by type, location etc. Through these functions, you
can conveniently control the air conditioner and by assigning each name to the set group, you can
manage the groups intuitively.
Reduced administrative cost
Because you can use AC SMART II to control all units, you can administer all the units with only one
administrator. Also by using the schedule function of AC SMART II, the administrator can operate the
units automatically without having to be on site.
Convenient GUI
AC SMART II provides intuitive pictogram and simple interface for user to easily use the functions.
Through the easy to use interfaces, the user can conveniently control the units without any separate
training.

Managing the automatic schedule operation & Saving the energy
The AC Smart can automatically run the air conditioner by setting the schedule.
When you register the schedule for a specific period by this schedule function, the\ unnecessary
operation of the air conditioner can be reduced and the energy can be efficiently saved. These
functions can efficiently performed by operating with a specific schedule such as school.
Various automatic control functions
The AC Smart offers various automatic control functions such as automatically switched running,
temperature limited running and time limited running as well as schedule. When the administrator sets
and executes these functions, various control functions such as maintaining a specific temperature
and limiting the air operation time can be automatically executed and managed by the AC Smart.
Protecting the system by the backup
The AC Smart offers the system information backup function for protecting the system from power
failure and other accidents, by which the stability of the system can be improved and the system can
be easily recovered from the accident.
Upgrading the software to the recent version
The AC Smart offers the function to upgrade the software to the recent version, by which the AC
Smart can be stably operated and a new function can be added.
Web server
The AC Smart offers the web server function to control the air conditioner by remotely accessing the
AC Smart via the network. The administrator can use the web server function to control the air
conditioner at the place other than the location where the AC Smart is installed.
E-mail notification
The AC Smart offers the function to notify the administrator of the critical error occurred during the
operation via the e-mail, by which the administrator can monitor the occurred error.
Extended interconnection
The AC Smart offers the extended interconnection function to control the air conditioner by
interconnecting with other devices. Basically, one AC Smart can control 64 air conditioners at
maximum. But, it can control 128 air conditioners at maximum when using the extended
interconnection function.
