●When compressor is operating, the normal discharge
temperature for cooling is 70~105℃, which is 10℃ above
higher than high pressure saturation temperature;
℃
●The normal temperature for heating is 65℃~90℃, which
is 10℃ above higher than high pressure saturation
temperature.
●When the unit is cooling, the defrosting temperature is
4~10℃ lower than high pressure value of system;
℃
●When the unit is heating, the defrosting temperature is
2℃different from the low pressure value of system
●Under cooling mode, the normal high pressure value is
20℃～55℃. With the change of ambient temperature and
operation capacity of system, the high pressure value of
system is 10℃～30℃ higher than ambient temperature.
The higher the ambient temperature, the temperature
℃
difference between them is smaller. When the unit is
cooling when the ambient temperature is 25~35℃, the
high pressure value of system is 44~53℃;
●Under heating mode, when the ambient temperature is

Code instruction and operation method
Wait and confirm the debugging command
of unit. Short press SW7 button on main
board to confirm the debugging of unit. 2s
later, the display of indicator of main board
is as below：
The startup of the unit is confirmed. 2s
later, the system will automatically select
"15_debugging operation for cooling) or
"16_debugging operation of heating) for
operation
according
to
temperature. If it needs to add refrigerant
while the refrigerant hasn't been added
before debugging, the refrigerant can be
added through low-pressure inspection
valve.
Debugging operation in cooling mode.
When the compressor is started up for 20
mins, if there's no malfunction, it will enter
into step 17 for debugging. If there's
malfunction during operation process, the
display is as below:
There's malfunction during debugging
operation under cooling mode. After
troubleshooting, it will enter into the next
step.
Debugging operation in heating mode.
When compressor is started up for 20min,
if there is no malfunction, it will enter into
step 17 for debugging. If there is
malfunction during operation, it will display
as below:
during debugging
There's malfunction
operation under heating mode.
Debugging for the complete unit is finished
and the system is at standby status.
