The detected sensor value is below 20H
sensor, (open-circuit) or above 1000H (short-circuit) for
60 seconds. The fault is fixable.
The detected sensor value is below 20H
(open-circuit) or above 1000H (short-circuit) for
60 seconds. The fault is fixable.
The detected sensor value is below 20H
temperature (open-circuit) or above 1000H (short-circuit) for
60 seconds. The fault is fixable.
circuit of After 3 minutes of compressor operation, the
line detected
(open-circuit) or above 1000H (short-circuit) for
60 seconds. Fixable when below 80°C.
The detected sensor value is below 20H
(open-circuit) or above 1000H (short-circuit) for
60 seconds. 。
An alarm is given five seconds after the current
limit is exceeded. Where there are 3 alarms
within 30 minutes, the fault code is displayed.
The fault is not fixable.
IPM overcurrent, short-circuit, overtemperature
and undervoltage. When the fault occurs three
times within 30 minutes, an alarm is given and
the fault is not fixable.
857 EEPROM data access error, 11 flashes.
The fault is not fixable.
line After
temperature detected by TD1 sensor is above
120°C. The compressor is shut off in 5 seconds
and an alarm is given. Where there are 3
alarms within 30 minutes, the fault code 11 is
displayed. The fault is not fixable.
The high pressure switch is activated. The fault
is corrected after the normal pressure is
restored for 2 minutes.
