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.

You can check whether the indoor unit address setting and the DIP switch setting of PI485 have been
set correctly as follows.
• LED01G will flash for as many as the connected number of indoor units.
• LED02G and LED03G will flash in switching back and forth. (When connecting LRA/CRUN
product, LED02G can blink more than LED03G).
When the LED is abnormal unlike the above description, recheck the address setting of the indoor unit
and DIP switch setting.

2. AC Smart II Installation
AC SMART II provides the lock function through the central control to disable individual control of
operating mode, fan level and temperature of the indoor unit. To use this lock function, you must
connect the 2PIN connector to the CN_DRY of PI485 or set DIP switch #5 to On depending on the
outdoor unit product type.
For PI485 with 8 DIP switches, set the DIP switch as follows depending on the type of outdoor unit on
which the PI485 is attached.

2. AC Smart II Installation
The following picture shows an example of the central control method when the 2PIN connector is
connected to the CN_DRY terminal or when the DIP switch #5 is set to ON.
1) Through the central controller, such as AC Smart, you can command the 'Cool operation, 20°C
setting, high fan level, temperature lock' function. This command can be provided by the remote
controller.
2) But if the user changes the temperature to 25°C with the remote controller, the applicable command
is sent tot eh outdoor unit and the 25°C setting is displayed on the remote controller.
3) The outdoor unit receives the applicable command and sends it to PI485.
4) PI485 cancels this command and resends the prior central control command. And the remote
controller redisplays the temperature of 20°C sent through the central control command.
This time, this is an example when the 2PIN connector is not connected to CN_DRY terminal or when
the DIP switch #5 is not set to ON.
When you command the “Cool operation, 20°C setting, high fan level, temperature lock” function
through central control, the applicable command is transmitted to the remote controller. “HL (Hard
Lock)” message displaying the central control status is displayed on the remote controller. If the user
sets the temperature to 25°C, the remote controller blocks the userʼs command.

Information: Connection setting when using simple central
controller with AC Smart
You can use a simple central controller with AC Smart. When you want to use a simple central
controller with AC Smart, connect the simple central controller in the order shown as follows.
1. Connect the BUS-A and BUS-B port of PI485 to the A and B terminal of the simple central
controller using the RS485 communication cable.
2. Set the rotary switch of the simple central controller to align with the group number of the
indoor unit to control. For example, when you want to control the indoor units with the address
of 00~ 0F, set the rotary switch to 0.
3. Set the DIP switch No. 1 of the simple central controller to OFF (Slave) and No. 2 to ON (LGAP
use mode).
Reference: Check V-net Label
Check the V-net Lbel on the right side of the case of the simple central controller. AC Smart II
can be simultaneously connected only to the product with the label.
You must connect the VCC and GND terminal of the simple central controller to connection of
PI485 or to a separate adapter. For more details, refer to the manual of the simple central
