Safety Precautions
This installation manual indicates you to install the wired remote controller
which is connected to the indoor unit. For installation of other optional
accessories, see an appropriate installation manual.
WARNING
CAUTION
E-2
◆ Read carefully this installation manual before
installation and check whether the remote controller
is installed correctly after installation.
◆ Do not attempt to install or repair this wired remote
controller by yourself.
◆ This remote 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 remote
controller.
◆ Ensure that the wall is strong enough to support the
weight of the remote controller.
◆ Must install the remote controller with rated power
supply.
◆ The remote controller must be installed according to
the national electrical rules by an installation specialist.
◆ When you want to disuse the remote controller,
consult authorized installation center.
◆ Do not use inflammable gases near the remote
controller.
◆ Do not install the remote 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 and 39°C.
◆ Do not spill water into the wired remote 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 remote controller is installed in a hospital or other
special places, it should not affect other electronic
devices.

Additional Function of the Wired Remote Controller
When using automatic ADDRESS of DVM PLUS, assign
MAIN ADDRESS to the indoor and outdoor unit.
The RMC is not assigned to the indoor unit. If you want to
control the air conditioner with the centralized controller,
you should operate the RMC switch of the indoor unit manually.
You can also assign the RMC using wired remote controller
without operating manually. (Only in COM2 available)
Assigning the indoor unit RMC with
the Wired Remote Controller
◆ You can use this function to control the indoor unit in
the centralized controller.
◆ It means that you assign the RMC with the wired remote
controller without operating the RMC switch manually.

Initial display
◆
is displayed if the group has never been set.
If the group is set, the LCD receives the current indoor
unit ADDRESS(main address) and group ADDRESS
(RMC) from the indoor unit and displays them.
Changing of group ADDRESS (RMC)
◆ Press the
button to select the required group
ADDRESS. Then, the group ADDRESS display flickers
and changes.
Setting the group ADDRESS
◆ Press the
button once to set the selected group
ADDRESS with the ‘beep’ sound.
Quit
◆ Press the
button again to quit the setting mode and
enter the operation mode.
If you press the
button in the mode except the
‘Canceling the group ADDRESS’, quit the ‘Setting the
RMC switch group ADDRESS mode’.
CAUTION
◆ When assigning the RMC, the wired remote
controller of each indoor unit should be installed
one to one.
◆ If you assign the RMC to the indoor unit with the
wired remote controller, the indoor unit is
controlled by the RMC(assigned with the wired
remote controller) in the centralized controller
even if the RMC is set to the indoor unit PCB
manually.
