Check resistance characteristics of TCJ sensor.
Check for trouble in indoor P.C. board.
F02
TC2 Sensor trouble
Check connection of TC2 sensor connector and wiring.
Check resistance characteristics of TC2 sensor.
Check for trouble in indoor P.C. board.
F03
TC1 Sensor trouble
Check connection of TC1 sensor connector and wiring.
Check resistance characteristics of TC1 sensor.
Check for trouble in indoor P.C. board.
F10
TA Sensor trouble
Check the connection of TA sensor connector and wiring.
Check resistance characteristics of TA sensor.
Check for trouble in indoor P.C. board.
L02
Outdoor units model disagreement trouble
Check outdoor unit model.
(Check whether the outdoor unit corresponds to Dx-coil Interface or not.)
L09
Indoor unit Power Code incorrect
Check the settings of DN Code 11 (See "Dx-coil interface configuration").
L22
Incompatible group combination of indoor units
Check indoor units model name.
Check for trouble in indoor P.C. board.
L30
Fan Motor operation monitor
Check the operation monitoring of the fan at terminals C7 / C8. If this contact is "CLOSED", the check code "L30" is
generated.
P10
Safety contact trouble
Check the contact at terminals C5 / C6. If the contact is "OPEN", the check code "P10" is generated. If this contact is
not used, a bridge connection should be installed on the terminals C5 / C6.
For the check code other than the above, refer to the service manual.
