A digital display is featured on the outdoor PCB.
The LED displays different codes in the following situations:

Standby:
“- -.”

Compressor operation: the running frequency.

Defrosting mode:
“dF” or alternative displays between running frequency and
“dF” (ach appears for 0.5s.)

Forced cooling mode: the LED displays
“FC” or alternative displays between running frequency and
“FC” (each appears for 0.5s).

Compressor pre-
heating: “PH” or alternative displays between running frequency
and “PH” (each appears for 0.5s.)

Oil return process: “RO” or alternative displays between running
frequency and “RO” (each appears for 0.5s.)

Low ambient cooling mode: “LC” or alternative displays between running
frequency and “LC” (each appears for 0.5s.)

PFC module protection occurs three times within 15 minutes:
“E6” or
alternates between displays of running frequency and “E6” (each appears for 0.5s.)

In protection or malfunction, the LED displays an error code or protection code.
“PH”, “RO”, “LC”, ”E6” are not suitable for
