When the input current for running compressor exceeds L2, running frequency will be reduced by 1 step. If
current still exceeds L2, frequency will be reduced by another 1 step until total current falls between L2 and
L3.
This protection cut in when the input current exceeds L1 for 2 seconds. Compressor will stop and it is
considered total current overload.
If input current < L3, the compressor frequency is reset based on the OD ambient, set and room
temperature.
