Fujitsu AGHG12KVCB - Current Release Control; Cooling Pressure Over-Rise Protection

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.

8-4. Cooling pressure over-rise protection
When the outdoor unit heat exchanger temperature reaches trigger condition below, the compressor
is stopped and trouble display is performed.
Trigger condition 65°C
