Parts to be checked / error description
device
Incorrect remote control setting --- The header remote
control has not been set (including two remote controls).
No signal can be received from the indoor unit.
System interconnection wires, indoor P.C. board, remote
control
--- No signal can be sent to the indoor unit.
Remote control, network adapter, indoor P.C. board ---
No data is received from the remote control or network
adapter.
System interconnection 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 control address setting error --- Two remote
controls are set as header in the double-remote control
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 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
