Parts to be checked / error description
Room temp. sensor (TA), indoor P.C.
board --- Open-circuit or short-circuit of the
room temp. sensor (TA) was detected.
TS sensor may be displaced,
disconnected or short-circuited.
Abnormal temperature was detected by
the temp. sensor of the IGBT heat sink.
Temp. sensor (TE / TS) may be connected
incorrectly.
Indoor P.C. board --- EEPROM error.
Outdoor P.C. board ---- In the case of
EEPROM error.
Current detect circuit, power voltage ---
Minimum frequency was reached in the
current releasing control or short-circuit
current (Idc) after direct excitation was
detected.
Compressor circuit --- Compressor lock
was detected.
Current detect circuit, outdoor unit P.C.
board --- Abnormal current was detected
in AC-CT or a phase loss was detected.
Malfunction of the case thermostat
Current, high-pressure switch circuit,
outdoor P.C. board --- Pressure sensor
error was detected or low-pressure
protective operation was activated.
Indoor address setting error --- There are
two or more header units in the group.
Indoor address setting error --- There is
at least one group-connected indoor unit
among individual indoor units.
Indoor address setting error --- Indoor
address group has not been set.
Indoor unit capacity has not been set.
In the case of outdoor P.C. board jumper
wire (for service) setting error.
Address setting, central control
remote controller, network adapter ---
Duplication of address in central control
communication.
Other outdoor unit error.
1) Communication error between IPDU
MCU and CDB MCU.
2) Abnormal temperature was detected by
the heat sink temp. sensor in IGBT.
External devices, outdoor unit P.C. board
--- Abnormal stop due to incorrect external
input into CN80.
Power supply phase sequence, outdoor
unit P.C. board --- Abnormal phase
sequence of the 3-phase power supply.
