[E03 error] (Master indoor unit)
[E03 error] is detected when the indoor unit cannot receive a signal sent from the main remote controller (and
central controller).
In this case, check the communication cables of the remote controllers A and B, the central control system X
and Y. As communication is disabled, [E03] is not displayed on the main remote controller and the central
controller. [E01] is displayed on the main remote controller and [97 error] on the central controller, respectively.
If [E03] occurs during an operation, the air conditioner stops.
[F29 error] / [12 error]
[F29 error] or [12 error] indicates detection of trouble which occurred on IC10 non-volatile memory (EEPROM)
on the indoor unit P.C. board during operation of the air conditioner. Replace the service P.C. board.
* If EEPROM has not been inserted when the power was turned on or if EEPROM data never be read/written,
the automatic address mode is repeated. In this time, the central controller displays [97 error].
[P31 error] (Sub indoor unit)
When the master unit of a group operation has detected [E03], [L03], [L07], or [L08] error, the sub unit of the
group operation detects [P31 error] and then it stops. There is no display of the check code or alarm history of
the main remote controller.
(In this model, the mode enters in automatic address set mode when the master unit has detected [E03], [L03],
[L07], or [L08] error.)
