Fujitsu ACUH12LUAS1 - Current Release Control

8-3. Current release control
The compressor frequency is controlled so that the outdoor unit input current does not exceeds cur-
rent limit value set according to the outdoor temperature.
The compressor frequency returns according to the operation mode, when the current becomes low-
er than the release value.
