Judgement and correction
P03 Abnormal discharge
temperature error
• Discharge temp.
detected at or
above the specifi ed
value
Stops when temp. exceeds
111 .
Alarm output on 4 pre-trips Recovery at restart 1. Check refrigerant cycle (gas
leak).
2.Trouble with electronic
expansion valve
3.Check discharge
temperature sensor (TD).
P05 CT disconnected
or AC power supply
error The current value transmitted
from the microcomputer on the
outdoor unit control substrate is
low.
When no AC power input for
more than 3 minutes: Pre-trip 5
times Recovery at restart Check outdoor unit control
PCB.
P15 Insuffi cient gas level
detected. • Discharge temperature is 95
or higher.
• Electronic expansion valve is at
Step 480.
• The current value from the
MDC is 2.0A or less.
When the above has continued
for 1 minute.
Recovery at restart 1.Check refrigerant cycle (gas
leak).
2.Trouble with electronic
expansion valve.
3.Check outdoor unit valve
opening.
P19 4-way valve locked
trouble.
• Judged after
5 minutes had
elapsed since the
compressor was
switched on.
The indoor unit heat exchanger
temperature drops even though
the compressor is switched
on during the heating mode.
[min(E1,E2)] is 10 or lower.
The indoor unit heat exchanger
temperature rises even though
the compressor is switched on
during the cooling mode.
E2 is 50 or higher Pre-trip 2
times Recovery at restart 1. Check 4-way valve.
2. Check 4-way valve wiring.
3. Check outdoor unit control
PCB.
P20 High-pressure
protection error
caused by cooling
high-load max (C1,
C2) temperature Halted if the temperature
exceeds "a" .
"a"=64 : Model 256, 366
"a"=61 : Model 486
Error output on 10 consecutive
pre-trips. Recovery at restart 1.Overload operation of
refrigerant cycle.
2.Check outdoor unit heat
exchanger temperature
sensor C1 and C2.
P22 Outdoor unit fan
motor trouble
• Inverter protection
circuit was
activated, or lock
was detected at
outdoor unit fan
motor.
Inverter stops after alarm is
detected. Pre-trip 4 times Recovery at restart 1.Position detection trouble.
2.Outdoor unit fan motor over-
current Protection circuit is
activated.
• Check outdoor unit control
PCB.
• Refer to outdoor unit fan
judgement methods.
P26 Inverter protector
circuit was activated.
G-Tr short-circuit
within the HIC circuit.
(Short time / 0.8
seconds or less)
HIC temperature
protection Inverter stops after alarm
is detected. Alarm is output
when inverter stops (pre-trip)
consecutively 4 times. Recovery at restart
Temperature dropped
1.Stops immediately even
when operations restarted.
• Layer short on the
compressor
2.Check HIC circuit.
• Wiring trouble
3.Heat sink and PCB (HIC)
• Contact trouble
