protective operation
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
Wiring error of compressor (open phase)
Compressor circuit --- Compressor lock was detected.
Wiring error of compressor (open phase)
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
--- Ps 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 power level has not been set.
In the case of outdoor P.C. board jumper wire (for service)
setting error
Address setting, central control remote control, 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
Indoor fan motor, indoor P.C. board --- Indoor AC fan
error (fan motor thermal relay activated) was detected.
An error was detected in the discharge temp. releasing
control.
High-pressure switch --- The IOL was activated or an
error was detected in the high-pressure releasing control
using the TE.
The power cable may be connected incorrectly. Check
open phase and voltages of the power supply.
Abnormal temperature was detected by the temp. sensor
of the IGBT heat sink.
Drain pipe, clogging of drainage, float switch circuit,
indoor P.C. board --- Drainage is out of order or the float
switch was activated.
There may be gas leakage from the pipe or connecting
part. Check for gas leakage.
4-way valve, indoor temp. sensors (TC/TCJ) --- An error
was detected due to temperature drop of the indoor unit
heat exchanger sensor when heating.
