Input Current Control
Outline
Unlike the inverter current control, this function will monitor the overall input current and will restrict the
compressor upper limit operating frequency as to prevent activation of the circuit breakers.

Upper limit current
The outdoor model type and the outdoor air temperature will determine the upper limit current value.
