Indication Contents
00
Operation OFF, Power OFF
01 Thermo-OFF
02 Alarm
03
Freeze protection overheating protection
05 Instantaneous power failure at outdoor unit
06
Instantaneous power failure at indoor unit
07
Stoppage of cooling operation due to low outdoor air

Stoppage of heating operation due to high outdoor air
temperature
10 Demand thermo OFF
13 Retry for Pd increase prevention
15 Vacuum/discharge gas temperature increase retry
16 Retry due to discharge gas SUPERHEAT decrease
17
IPM error retry, instantaneous over current of inverter
retry, electronic thermal activation of inverter retry, abnor-
mal current sensor of inverter retry
18
Retry due to inverter voltage decrease
Retry due to
Inverter Over
voltage
19 Other retry
20
Different operation mode between indoor/outdoor units
(Only for individual twin/triple/quad types)
21
Forced thermo-OFF
(Only for simultaneous twin/triple/quad types)
22
Forced thermo-OFF
(During compressor pre-heating)
24
Thermo-OFF during energy saving operation mode
Cancelation of Forced Thermo OFF
Turn ON the power source and wait for more than 30 seconds. Then press PSW1 and PSW3 simultaneously for more
than 3 seconds.
Forced thermo-OFF (indoor unit error code 22) will be cancelled.
However, this function may damage the compressor, use only on inevitable occasion.
In case of using the remote control switch (PC-P1HE), the cancellation is also available with it.
When “operation is limited” indication flashes on the remote control LCD, press FAN SPEED and LOUVER switches
simultaneously for more than 3 seconds.
“Operation is limited” indication is disappeared and operation is available.
