Compressor
discharge temp
°C(°F)
 When compressor starts, discharge temp in
cool mode is within 70~105°C(158~221°F)
and at least 10°C(50°F) higher than the high
pressure saturation temp.
 As for temp in heat mode, it is within
65~90°C(149~194°F) and at least
10°C(50°F) higher than the high pressure
saturation temp.
3 Defrosting temp °C(°F)
 In cool mode, defrosting temp is
4~10°C(39~50°F) lower than system’s high
pressure value.
 In heat mode, defrosting temp is about
2°C(36°F) different from system’s low
pressure value.

System high
pressure
°C(°F)
 In cool mode, the normal high pressure
value is within 20~55°C(68~131°F).
According to the change of ambient temp
and system’s operating capacity, the high
pressure value will be 10~30°C(50~86°F)
higher than ambient temp. The higher
ambient temp is, the smaller temp difference
is. If ambient temp is 25~35°C(77~95°F) in
cool mode, system’s high pressure value will
be within 44~53°C(111~127°F).
 In heat mode, if ambient temp is above
-5°C(23°F), system’s high pressure value is
within 40~52°C(104~126°F). If ambient temp
is low and many IDUs are turned on, the high
pressure will be lower.

System low
pressure
°C(°F)
 When ambient temp in cool mode is
25~35°C(77~95°F), the low pressure value
is 0~8°C(32~46°F).
 When ambient temp in heat mode is above
-5°C(23°F), the low pressure value is
-15~8°C(5~46°F).

Opening degree of
thermal EXV
PLS
 In cool mode, the thermal electronic
expansion valve remains 480PLS.
 In heat mode, the adjustable opening degree
of EXV is 60~480PLS.
