P9

Abnormality of pipe temperature ther-
mistor / Condenser-Evaporator (TH5)

1

The unit is in three-minute resume pro-
tection mode if short/open of thermistor
is detected. Abnormal if the unit does
not get back to normal within three min-
utes. (The unit returns to normal opera-
tion, if it has normally reset.)

2

Constantly detected during cooling, dry-
ing, and heating operation (except
defrosting)
Short: 90

:

or more

Open: -40

:

or less

1

Defective thermistor 

characteristics

2

Contact failure of connector

(CN29) on the indoor controller
board. (Insert failure)

3

Breaking of wire or contact 

failure of thermistor wiring.

4

Temperature of thermistor is
90

:

or more or -40

:

or less

caused by defective refrigerant
circuit.

5

Defective indoor controller

board.

1

~

3

Check resistance value of thermistor.
For characteristics, refer to (P1) above.

2

Check contact failure of connector (CN29)
on the indoor controller board. 
Refer to page 45.
Turn the power on and check restart after
inserting connector again.

4

Operate in test run mode and check pipe
<condenser / evaporator> temperature with
outdoor controller circuit board.  If pipe 
<condenser / evaporator> temperature is
exclusively low (in cooling mode) or high (in
heating mode), refrigerant circuit may have
defective.

5

Operate in test run mode and check pipe
<condenser / evaporator> temperature with
outdoor control circuit board.  If there is 
exclusive difference with actual pipe 
<condenser / evaporator> temperature
replace indoor controller board.
There is no abnormality if none of above
comes within the unit.
Turn  the power off and on again to operate.

E4

Remote controller signal receiving error

1

Abnormal if indoor controller board can
not receive normally any data from
remote controller or from other indoor
controller board for three minutes.

2

Indoor control board cannot receive any

signal from remote controller for two
minutes.

1

Check disconnection or looseness of indoor
unit or transmission wire of remote controller.

2

Set one of the remote controllers “main”.
If there is no problem with the action above.

3

Diagnose remote controllers.

a) When “RC OK” is displayed,

Remote controllers have no problem. 
Put the power off, and on again to check.
If abnormality generates again, replace
indoor controller board.

b) When “RC NG” is displayed,

Replace remote controller.

c) When “RC E3” or “ERC 00-06” is dis-

played, noise may be causig abnormality.

If the unit is not normal after replacing
indoor controller board in group control,
indoor controller board of address “0”
may be abnormal.

E5

Remote controller transmitting error 

1

Abnormal if indoor controller board cannot
check the blank of transmission path for
three minutes.

2

Abnormal if indoor controller board cannot
finish transmitting 30 times consecutively.

12

Turn the power off, and on again to check.
If abnormality generates again, replace
indoor controller board.

1

Contact failure at transmission
wire of remote controller

2

All remote controllers are set
as “sub” remote controller. In
this case, E0 is displayed on
remote controller, and E4 is
displayed at LED (LED1, LED2)
on the outdoor controller circuit
board.

3

Defective transmitting receiving
circuit of remote controller

4

Defective transmitting receiving
circuit of indoor controller board.

5

Noise has entered into the
transmission wire of remote
controller.

1

Defective transmitting receiving
circuit of indoor controller board.

2

Noise has entered into the
transmittion wire of remote
controller.

E6

1

Contact failure, short circuit or,
mis-wiring (converse wiring) of
indoor/outdoor unit connecting
wire

2

Defective transmitting receiving
circuit of indoor controller board

3

Defective transmitting receiving
circuit of indoor controller board

4

Noise has entered into indoor/
outdoor unit connecting wire.

Check LED display on the outdoor control
circuit board. (Connect A-control service tool,
PAC-SK52ST.)
Refer to EA-EC item if LED displays EA-EC.

1

Check disconnection or looseness of indoor/
outdoor unit connecting wire of indoor unit or
outdoor unit.

Check all the units in case of twin triple   
indoor unit system.

2

-

4

Turn the power off, and on again to
check. If abnormality generates again,
replace indoor controller board or outdoor 
controller circuit board.

Other indoor controller board may have 
defective in case of twin triple indoor unit 
system.

E7

Indoor/outdoor unit communication
error (Transmitting error)
Abnormal if “1” receiving is detected 30
times continuously though indoor controller
board has transmitted “0”.

1

Defective transmitting receiving
circuit of indoor controller board 

2

Noise has entered into power
supply.

3

Noise has entered into outdoor
control wire.

1

~

3

Turn the power off, and on again to

check. If abnormality generates again,
replace indoor controller board.

Indoor/outdoor unit communication
error (Signal receiving error)

1

Abnormal if indoor controller board 
cannot receive any signal normally for
six minutes after putting the power on.

2

Abnormal if indoor controller board 
cannot receive any signal normally for
three minutes. 

3

Consider the unit abnormal under the
following condition: When two or more
indoor units are connected to one 
outdoor unit, indoor controller board 
cannot receive a signal for three minutes
from outdoor controller circuit board, a
signal which allows outdoor controller
circuit board to transmit signals. 

In case of checking pipe temperature
with outdoor controller circuit board,
be sure to connect A-control service
tool (PAC-SK52ST).
