[E03 error] (Master indoor unit)<br />
<br />
[E03 error] is detected when the indoor unit cannot receive a signal from the remote controller<br />
(also central controller).<br />
Check A and B remote controllers and communication lines of the central control system U3 and U4.<br />
As communication is impossible, this check code [E03] is not displayed on the remote controller and the central<br />
controller. [E01] is displayed on the remote controller and [C06 error] is displayed on the central controller.<br />
If these check codes generate during operation, the air conditioner stops.<br />
[F29 error]<br />
This check code indicates a detection error of IC10 non-volatile memory (EEPROM) on the indoor unit P.C.<br />
board, which generated during operation of the air conditioner. Replace the service P.C. board.<br />
∗ When EEPROM was not inserted when power supply turned on or when the EEPROM data read/write<br />
operation is impossible at all, the automatic address mode is repeated. In this time, [97 error] is displayed on<br />
the central controller.<br />

3 minutes)<br />

[SET] is displayed<br />
on remote controller.<br />

[P31 error] (Follower indoor unit)<br />
When the master unit of a group operation detected [E03], [L03], [L07] or [L08] error, the follower unit of the<br />
group operation detects [P31 error] and then the unit stops.<br />
There is no display of the check code or alarm history of the remote controller. (In this model, the mode enters<br />
in automatic address set mode when the master unit detected [L03], [L07] or [L08] error.)<br />
