Error code display and actions

The error codes are viewed on the display screen. After the error codes are displayed, the sys-
tem is shut off for 60 sec. and re-started (except for ba11). If the same error occurs more than
6 times within 60 minutes, the A/C system will be completely stopped. In this case, it can only
start again if the error has been solved and the system has been completely switched off and
on again.
