There are 2 methods to connect the remote controller cable to the
indoor unit. One is the connection using contained connecting cable,
and the other is the connection the remote controller cable is connected
to the exclusive terminal block of the indoor unit.
Exclusive terminal block for remote controller connection method is dif-
ferent depending on each model. Modify the remote controller cable as
per below description and connect it.
(For the details, refer to the installation manual of the indoor unit to be
used.)
