EXCT
(2P plug (red))

Relay (field supply)

Relay coil signal

Indoor unit control PCB

Note: The length of the wiring from the indoor unit control PCB to the relay must be 6-9/16 ft. 

or less.

DISP
(CN010)

2P plug (white): Short-circuiting this plug allows the unit to be operated by the remote 
controller, even if it is not connected to an outdoor unit. (In this case, alarm "E04," which 
indicates trouble in the serial communication between the indoor and outdoor unit, does not 
occur.)

CHK
(CN011)

2P plug (white): Test pin. Short circuiting this plug allows the operation of the indoor fan 
motor (high) and fl ap motor (F1 position) to be checked.However this test operation stops 
if the indoor unit protection mechanism is activated. The unit can be operated even if the 
remote controller and outdoor unit are not connected. However even if the remote controller 
cannot be connected, it cannot be used to operate the unit. This function can be used for 
short-term tests.
