Startup is confirmed. After displaying for
2s, system will choose "15_Cooling
debugging" or "16_Heating debugging"
according to ambient temperature. If the
AE On
project requests to add refrigerant but
it is not complemented before
debugging, then refrigerant can be
added in this process through the
L-VALVE.
Debugging for cooling mode. If no
malfunction occurs for 20min when
AC On compressor is running, then system will
start progress 17; If malfunction
occurs,unit will display as below:
Malfunction occurs when debugging for
cooling mode. After all malfunctions

Debugging for heating mode. If no
malfunction occurs for 20min when
AH On compressor is running, then system will
start progress 17; If malfunction
occurs,unit will display as below:
Malfunction occurs when debugging for
Error heating mode. After all malfunctions

The entire unit has finished debugging
OFF On
and under standby-by condition.

℃
●When compressor starts, discharge temp in cool
mode is within 70~105℃ and at least 10℃ higher
than the high pressure saturation temp;
℃
●As for temp in heat mode, it is within 65~90℃
and at least 10℃ higher than the high pressure
saturation temp.
●In cool mode, defrosting temp is 4~10℃ lower
than system's high pressure value;
℃
●In heat mode, defrosting temp is about 2℃
different from system's low pressure value.
●In cool mode, the normal high pressure value is
within 20℃~55℃. According to the change of
ambient temp and system's operating capacity,
the high pressure value will be 10℃~30℃ higher
than ambient temp. The higher ambient temp is,
the smaller temp difference is. If ambient temp is
℃
25~35℃ in cool mode, system's high pressure
value will be within 44~53℃.
●In heat mode, if ambient temp is above -5℃,
system's high pressure value is within 40~52℃. 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℃,
the low pressure value is 0~8℃.
℃
●When ambient temp in heat mode is above -5℃,
the low pressure value is -15~8℃.
●In cool mode, the thermal electronic expansion
valve remains 480PLS.
PLS
●In heat mode, the adjustable opening angle of
EXV is 60~480PLS.
