Error Code Table - AERMEC SGE250W Installation Manual

ERROR CODE TABLE

If malfunctioning occurs during system functioning, the
units show the relative alarm code which easily permits
to the After-Sales Service Area to identify the cause of
errors.
When the indoor unit encounters a recognized error, the
operation lamp will flash in a corresponding series, the
timer lamp may turn on or begin flashing, and an error
code will be displayed. These error codes are described
in the following tables.
