16.2 Protection Control for Cooling & Soft Dry Operation
16.2.1 Outdoor Air Temperature Control
 The compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the
diagram below.
 This control will begin 1 minute after the compressor starts.
 Compressor frequency will adjust base on outdoor air temperature.
 The compressor will be stopped to avoid compressor overloading.
-10°C
-12°C

16.2.2 Cooling Overload Control
 Detects the Outdoor pipe temperature and carry out below restriction/limitation (Limit the compressor Operation
frequency).
 The compressor stop if outdoor pipe temperature exceeds 60°C.
 If the compressor stops 4 times in 20 minutes, Timer LED blinking (F95 indicated: outdoor high pressure rise
protection).
16.2.3 Freeze Prevention Control 1
 When indoor heat exchanger temperature is lower than 0°C continuously for 6 minutes, compressor will stop
operating.
 Compressor will resume its operation 3 minutes after the indoor heat exchanger is higher than 5°C.
 At the same time, indoor fan speed will be higher than during its normal operation.
 If indoor heat exchanger temperature is higher than 13°C, the fan speed will return to its normal operation.
16.2.4 Freeze Prevention Control 2
 Control start conditions
o During Cooling operation and soft dry operation
 During thermo OFF condition, indoor intake temperature is less than 10°C or
 Compressor stops for freeze prevention control
o Either one of the conditions above occurs 5 times in 60 minutes.
 Control contents
o Operation stops
o Timer LED blinks and “H99” indicated
