Safety Precautions
This installation manual indicates you to install the centralized controller which is
connected to the indoor unit. For installation of other optional accessories, see an
appropriate installation manual.
WARNING
CAUTION
Read carefully this installation manual before installation
and check whether the centralized controller is installed
correctly after installation.
Do not attempt to install or repair this centralized
controller by yourself.
This centralized controller contains no user-serviceable
parts. Always consult authorized service personnel for
repairs.
When moving, consult authorized service personnel
for disconnection and installation of the centralized
controller.
Ensure that the wall is strong enough to support the
weight of the centralized controller.
The centralized controller must be installed according to
the national electrical rules by an installation specialist.
When you want to disuse the centralized controller,
consult authorized installation center.
Do not use inflammable gases near the centralized
controller.
Do not install the centralized controller in a location
where it will come into contact with the combustible
gases, machine oil, sulphide gas, etc.
Avoid a location where acid/alkali solution or special
spray is used.
Choose a location that is dry and sunny, but not exposed
to direct sunlight. Available temperature is between
0°C(32°F) and 39°C(102°F).
Do not spill water into the centralized controller.
Do not give tensile strength to the cable to avoid
disconnection.
Do not press buttons with a pointed thing.
Do not connect the power cable to the control terminal.
If the centralized controller is installed in a hospital or
other special places, it should not affect other electronic
devices.

Adjust K2 DIP switch(SW05) on the indoor unit PCB to the
'OFF' position. It means use of the centralized controller.

 If the RMC (1) switch is set to other numbers besides 0, 1, and 2,
communication error occurs.
 According to the number of installed indoor units, transmitter connection
setup is changed. For detailed installation structure, refer to the installation
example of central controller + transmitter (pages 7 to 17).

RMC(2)
Note
The number of button on the centralized controller is decided by
the RMC(2) addresses of indoor units.
Refer to the table below.
RMC(2) Address 0 1 2 3 4 5 6 7 8 9 A B C D E F
Button No.
Note

 Individual control
means a centralized controller controls only 1 indoor unit. In this case,
you should assign the RMC address to the indoor unit.
 Group control
means a centralized controller controls more than 2 indoor units. In this case,
you should assign the RMC address to each indoor unit to be controlled by the
centralized controller and cannot use a wireless remote controller.

Different Levels of the Centralized Controller
 Adjust the DIP switch in the centralized controller PCB and set a
level. This will enable the user to control the indoor units
connected to the centralized controller according to the set level.

centralized controller is pressed
once, the operating lamp turns on,
the indoor unit falls into a standby
state, and the indoor unit can be
turned ON/OFF using the wired/
wireless remote controller and the
indoor unit button. (The indoor
units cannot be operated with the
'All ON/OFF' button)
 If the 'All ON' button of the
centralized controller is pressed
twice, the operating lamp turns off,
and it is not possible to control the
indoor unit with a wired/wireless
remote controller or an indoor unit
button.
 The LEVEL of the centralized controller is ‘0’ when all the
switches are in the 'OFF' position.
 The power is reset when the ADDRESS of the centralized
controller is changed.
 When attempting to change the LEVEL of the centralized
controller, reset the main system’s power or turn off and
then on the power of all the indoor units using the
'All ON/OFF' button.

Centralized Controller Communication Option
Setup Method

When setting the option by operating the DIP switch (DS01) of
Centralized Controller PCB, the Centralized Controller can be
controlled according to the setup option.

 All DIP switches are set to OFF when a Centralized
Controller is delivered.
 If the option of a Centralized Controller is changed, the





changed option is applied only when the power of the
central controller is reset.
When the option is changed, the changed option is applied
only when the indoor unit is controlled at least once by using
the all room ON/OFF button of the Centralized Controller.
Example) If the indoor unit is operated, send the changed
signal to the indoor unit by pressing the all room
ON button. Or press the all room OFF button.
(But, when pressing the all room OFF button, the
operating indoor unit is turned off.) If not using
an indoor unit, send the changed signal to the
indoor unit by pressing the all room OFF button.
The communication option setup is executed without the
relation with the level setup.
If the communication option is wrong, an error mark is
displayed as below.
If transmitters have a different communication speed each
other, the communication speed must be fixed to 2400 bps.
However, the communication speed must be fixed to 2400
bps without relation with transmitter models when
function controller (MCM-A100) is connected to the
Centralized Controller.
Caution
If there are more than one centralized controllers installed,
the communication option settings in the centralized controller
must all be set as same.
