3.5.2. Remote controller custom setting
Use the following steps to select the custom code of the remote controller. (Note that the
air conditioner cannot receive a signal if the air conditioner has not been set for the match-
ing custom code.)
(1) Press [START/STOP (
)] until only the clock is dis-
played on the remote controller display.
(2) Press [MODE] for at least 5 seconds to display the cur-
rent custom code (initially set to A).
(3) Press [TEMP. (
/ )] to change the custom code
between
A↔B↔C↔D
.
Match the code on the display to the air conditioner
custom code.
(4) Press [MODE] again to return to the clock display. The
custom code will be changed.
• If no buttons are pressed within 30 seconds after the custom code is displayed, the
system returns to the original clock display. In this case, start again from step 1.
• The air conditioner custom code is set to A prior to shipment.
4. OPTIONAL INSTALLATION WORK

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.
