5914.2 Protection Control For Cooling & Soft Dry Operation14.2.1 Outdoor Air Temperature Control The maximum current value is regulated when the outdoor air temperature rise above 57.2°F in order to avoidcompressor overloading.101.3°F99.5°FCompressor OFFCompressor ONOutdoor Air Temperature The compressor will be stopped at outdoor air temperature ≤ -4°F. The unit still operate within the temperaturerange.-0.4°F-4°FCompressor OFFCompressor ONOutdoor Air Temperature14.2.2 Cooling Overload Control Pipe temperature limitation / restriction.o Detects the outdoor pipe temperature and carry out restriction / limitation below (Limit the compressoroperation frequency)o The compressor stops if outdoor pipe temperature exceeds 141.8°F.o If the compressor stops 4 times in 20 minutes, Timer LED blinks (“F95” indicated: Outdoor high pressure riseprotection)14.2.3 Freeze Prevention Control 1 When indoor heat exchanger temperature is lower than 32°F continuously for 6 minutes, compressor will stopsoperation. Compressor will resume its operation 3 minutes after the indoor heat exchanger is higher than 41°F. At the same time, indoor fan speed will be higher than during its normal operation. If the indoor heat exchanger temperature is higher than 55.4°F for 5 minutes, the fan speed will return to itsnormal operation.14.2.4 Freeze Prevention Control 2 Control start conditionso During Cooling operation and soft dry operation During thermo OFF condition, indoor intake temperature is less than 50°F or Compressor stops for freeze prevention controlo Either one of the conditions above occurs 5 times in 60 minutes. Control contentso Operation stopso Timer LED blinks and “H99” indicated
