Parts to be checked / error description
Incorrect remote controller setting --- The header remote controller has
not been set (including two remote controllers).
No signal can be received from the indoor unit.
System interconnecting wires, indoor P.C. board, remote controller
--- No signal can be sent to the indoor unit.
Remote controller, network adapter, indoor P.C. board --- No data is
received from the remote controller or network adapter.
System interconnecting wires, indoor P.C. board, outdoor P.C. board -
-- Serial communication error between indoor unit and outdoor unit
Indoor address setting error --- The same address as the self-address
was detected.
Remote controller address setting error --- Two remote controllers are
set as header in the double-remote controller control.
(* The header indoor unit stops raising alarm and follower indoor units
continue to operate.)
Indoor P.C. board --- Communication error between main MCU and
motor microcomputer MCU
Indoor P.C. board --- Regular communication is not possible between
header and follower indoor units or between twin header (main) and
follower (sub) units.
Communication error between IPDU and CDB
Heat exchanger sensor (TCJ), indoor P.C. board --- Open-circuit or
short-circuit of the heat exchanger sensor (TCJ) was detected.
Heat exchanger sensor (TC), indoor P.C. board --- Open-circuit or
short-circuit of the heat exchanger sensor (TC) was detected.
Outdoor temp. sensor (TD), outdoor P.C. board --- Open-circuit or
short-circuit of the discharge temp. sensor was detected.
Outdoor temp. sensors (TE/TS), outdoor P.C. board --- Open-circuit or
short-circuit of the heat exchanger temp. sensor was detected.
TL sensor may be displaced, disconnected or short-circuited.
Outdoor temp. sensor (TO), outdoor P.C. board --- Open-circuit or
short-circuit of the outdoor air temp. sensor was detected.
Room temp. sensor (TA), indoor P.C. board --- Open-circuit or short-
circuit of the room temp. sensor (TA) was detected.
TS (1) 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 --- 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. Entire stop
Indoor power level has not been set.
In the case of outdoor P.C. board jumper wire (for service) setting error Entire stop
