14.2 Protection Control For Cooling & Soft Dry Operation
14.2.1 Outdoor Air Temperature Control

The maximum current value is regulated when the outdoor air temperature rise above 57.2°F in order to avoid
compressor overloading.
101.3°F
99.5°F
Compressor OFF
Compressor ON
Outdoor Air Temperature

The compressor will be stopped at outdoor air temperature ≤ -4°F. The unit still operate within the temperature
range.
-0.4°F
-4°F
Compressor OFF
Compressor ON
Outdoor Air Temperature
14.2.2 Cooling Overload Control

Pipe temperature limitation / restriction.
o
Detects the outdoor pipe temperature and carry out restriction / limitation below (Limit the compressor
operation 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 rise
protection)
14.2.3 Freeze Prevention Control 1

When indoor heat exchanger temperature is lower than 32°F continuously for 6 minutes, compressor will stops
operation.

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 its
normal operation.
14.2.4 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 50°F or
 Compressor stops for freeze prevention control
o
Either one of the conditions above occurs 5 times in 60 minutes.
