11-2 2 remote controllers control
(Controlling 1 indoor unit by 2 remote controllers)
• When using 2 remote controllers, one must be set to “MAIN”
and the other to “SUB”.
MAIN/SUB CHANGEOVER
(1) Insert a
screw driver into the recess between the upper
and lower part of remote controller and, working from the 2
positions, pry off the upper part.
The remote controller PC board is attached to the upper
part of remote controller.
(Refer to Fig. 30)
(2) Turn the MAIN/SUB changeover switch on one of the 2
remote controllers PC boards to “S”. (Leave the switch of
the other remote controllers set to “M”.)
(Refer to Fig. 31)
Wiring Method
(See “8. ELECTRIC WIRING WORK” and “9. WIRING EXAM-
PLE AND HOW TO SET THE REMOTE CONTROLLER” on
page from 10 to 12.)
(3) Remove the control box lid.
(4) Add 2nd remote controller to the transmission terminal
block (P1, P2) in the control box. (There is no polarity.)
(Refer to Fig. 28 on page 11 and Table 4 on page 11)
11-3 COMPUTERISED CONTROL
(FORCED OFF AND ON/OFF OPERATION)
See “FIELD SETTING” on page 12 for local settings.
(1) Wire specifications and how to perform wiring
• Connect the input from outside to terminals T1 and T2 of
the transmission terminal block.
(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.
11-4 CENTRALIZED CONTROL
• For centralized control, it is necessary to designate the group
No. For details, refer to the manual of each optional control-
lers for centralized control.
12. TEST OPERATION
Refer to the section of “FOR THE FOLLOWING ITEMS,
TAKE SPECIAL CARE DURING CONSTRUCTION AND
CHECK AFTER INSTALLATION IS FINISHED.” on page 4.
• Make sure if the service lids are closed on the indoor and out-
door units.
• After finishing the construction of refrigerant pipe, drain pipe
and electric wire, conduct the check operation referring to the
installation manual of the outdoor unit.
• The operation lamp of the remote controller will flash when a
malfunction occurs. Check the malfunction code on the liquid
crystal display to identify the point of trouble. An explanation
of malfunction codes and the corresponding trouble is pro-
vided in the installation manual of the outdoor unit.
It any of the items in Table 6 are displayed, there may be a
problem with the wiring or power, so check the wiring again.

• If “U3” is lit up, the malfunction code shows the check opera-
tion has not been performed yet.
12-1 HOW TO DIAGNOSE FOR MALFUNCTION
With the power on, it is possible to monitor the type of mal-
function by looking at the malfunction code displayed in
the remote controller.
