SAFETY AND MAINTENANCE
To check the parameters on the re-
frigerant side, open door 1 and you’ll
see the PCB like the following (diffe-
rent for 1-phase and 3-phase unit):
the digital display will show the pre-
sent compressor frequency (‘0’ will di-
splay if the unit is off or error code will
display if error occurs) . Long press
the check button and the digital di-
splay will show the operating mode,
and then press the check button in
sequence . The digital display will
show the value, the implication of the
value is shown in the diagram below:
Number
Implication
0
Frequency of compressor at present
1
Operation mode (0——Standby, 2——COOL,
3——HEAT, 5——refrigerant recovery)
2
Fan speed
3
Frequency from hydraulic module
4
Frequency after restriction by the outdoor unit
5
Temperature of tube at outlet/inlet of condenser
when in cool/heat mode
6
Outdoor air temperature
7
Discharge temperature
