When compressor starts, discharge temp in cool mode is
within 70~105℃(158~221℉) and at least 10℃(50℉) higher
than the high pressure saturation temp;
As for temp in heat mode, it is within 65~90℃(149~194℉)
and at least 10℃(50℉) higher than the high pressure
saturation temp.
In cool mode, defrosting temp is 4~10℃(39~50℉) lower
than system's high pressure value;
In heat mode, defrosting temp is about 2℃(36℉) different
from system's low pressure value.
In cool mode, the normal high pressure value is within 20℃
~55℃(68~131℉). According to the change of ambient temp
and system's operating capacity, the high pressure value will
be 10℃~30℃(50~86℉) higher than ambient temp. The
higher ambient temp is, the smaller temp difference is. If
ambient temp is 25~35℃(77~95℉) in cool mode, system's
high pressure value will be within 44~53℃(111~127℉).
In heat mode, if ambient temp is above -5℃(23℉), system's
high pressure value is within 40~52℃(104~126℉). If
ambient temp is low and many IDUs are turned on, the high
pressure will be lower.
When ambient temp in cool mode is 25~35℃(77~95℉), the
low pressure value is 0~8℃(32~46℉).
When ambient temp in heat mode is above -5℃(23℉), the
low pressure value is -15~8℃(5~46℉).
In cool mode, the thermal electronic expansion valve
remains 480PLS.
In heat mode, the adjustable opening angle of EXV is
60~480PLS.

When compressor works normally, the current is no more
than22.6A.
When ambient temp is below 35℃(95℉), IPM temp is lower
than 80℃(176℉) and the highest temp won't be above 95℃
(203℉).
