12-2 Control by 2 Remote Controllers (Controlling
1 indoor unit by 2 remote controllers)
When using 2 remote controllers, one must be set to "MAIN"
and the other to "SUB".
12-3 Main/Sub changeover
1. Insert a wedge-head screwdriver into the recess between
the upper and lower part of the remote controller and,
working from the 2 positions, pry off the upper part. (See
figure 14)
(The remote controller PC board is attached to the upper
part of the remote controller.)
2. Turn the main/sub changeover switch on one of the two
remote controller PC boards to "S". (See figure 17)
(Leave the switch of the other remote controller set to "M".)

12-4 Computerized control (forced off and on/off
operation)
1. Wire specifications and how to perform wiring.
• Connect input from outside to terminals T1 and T2 of
the terminal board (remote controller to transmission
wiring).
See figure 11
1 Input A
2. Actuation
• The following table explains "forced off" and "on/off
operations" in response to input A.
3. How to select forced off and on/off operation
• Turn the power on and then use the remote controller to
select operation.
• Set the remote controller to the field set mode. For
details, refer to the chapter "How to set in the field", in
the manual of the remote controller.
• When in the field set mode, select mode No. 12, then set
the first code (switch) No. to "1". Then set second code
(position) No. to "01" for forced off and to "02" for on/off
operation. (forced off at factory set.) (See figure 23)

2 Mode No. 4 Field set mode
12-5 Centralized control
For centralized control, it is necessary to designate the group
No. For details, refer to the manual of each optional controller
for centralized control.
13. INSTALLATION OF THE DECORATION
PANEL
Read the chapter "Test operation" on page 32 before making
a test run without attaching the decoration panel.
Refer to the installation manual delivered with the decoration
panel.
After installing the decoration panel, ensure that there is no
space between the unit body and decoration panel. Otherwise air
may leak through the gap and cause dewdrop. (See figure 16)
14. TEST OPERATION
Refer to the installation manual of the outdoor unit.

The operation lamp of the remote controller will blink when
an error occurs. Check the error code on the liquid crystal
display to identify the trouble. An explanation of error codes
and the corresponding trouble are provided on "Caution for
servicing" of the outdoor unit.
If any of the items in the table below are displayed, there may
be a problem with the wiring or power, so check the wiring
again.
