How to set the remote controller custom code
(1) Press
until the indicators on the remote controller turn off.
(2) Press down [MODE] for more than 5 seconds.
The current custom code will be displayed (initially set to
).
(3) Press [TEMP./SELECT (
)] to change the custom code between
A (
) ↔ B ( ) ↔ C ( / ) ↔ D ( ).
* Match the custom code on the display to the air
conditioner custom code.
(4) Press [MODE] again.
The custom code will be set.
The display will return to the original display.
• To change the air conditioner custom code, contact an authorized service
personnel (initially set to
).
• If you do not press any buttons for 30 seconds after the custom code is displayed,
the display returns to the original display. In this case, repeat the setting from step 2.
• Depending on the remote controller, the custom code may return to
when
replacing the batteries. In this case, reset the custom code as necessary. If you
do not know the air conditioner custom code, try each code until you fi nd the code
which operates the air conditioner.
4. OPTIONAL INSTALLATION WORK
CAUTION
• Before installing, be sure to disconnect all power supply.
• Do not touch the heat exchanger.
• When installing or removing parts of the air conditioner, be sure that the wire is not

4.1.2. External input and output
■
External input
• Indoor unit functions such as Operation/Stop or Forced stop can be done by using
indoor unit terminals.
• “Operation/Stop” mode or “Forced stop” mode can be selected with function setting of
indoor unit.
•
A twisted pair cable (22 AWG) should be used. Maximum length of cable is 492 ft. (150 m).
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• The wire connection should be separate from the power cable line.
● Dry contact terminal
When a power supply is unnecessary at the input device you want to connect, use the Dry
contact terminal.
