Fujitsu AOUH12LPAS1 - Low Outdoor Temperature Protection; Current Release Control; Cooling Pressure Over-Rise Protection

8-3. Current release control
The rotation number of compressor is controlled so that the outdoor unit input current does not ex-
ceeds current limit value set according to the outdoor temperature.
The rotation number of compressor returns according to the operation mode, when the current be-
comes lower 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 149.0°F (65°C)
8-5. Low outdoor temperature protection
When the outdoor temperature sensor detects lower than the trigger condition below, the compres-
sor is stopped.
Operation mode Cooling/Dry
Trigger condition 5°F (-15°C)
Release condition 14°F (-10°C)
