2.4 Check Buttons
Refrigerant system SW2 check button
Button SW2 is used to check the parameters of the refrigerant system. Refer to Table 4‐2.2 First, press Button SW2 for 3
seconds and the first parameter (operating mode) will be displayed. Then, on each subsequent press, the next parameter
is displayed.
Table 4‐2.4: SW2 system check
Number Parameters displayed on digital display Remarks
1 Mode 0: standby; 2: cooling; 3: heating; 4 forced cooling.
2 Fan speed
The fan speed index is related to the fan speed in rpm as described in Table 3‐4.1 in Part 3, 4.6
“Outdoor Fan Control”.
3 Capacity requirements
Compressor frequency
4 Capacity requirements(Correct) Compressor frequency
5 Frequency limit code
0: Without restriction
1: Compressor frequency restriction by o
utdoor ambient temperature
2:
Compressor frequency restriction by c
ondenser temperature
3:
Compressor frequency restriction by actual c
urrent
4:
Compressor frequency restriction by
voltage AC
5:
Compressor frequency restriction by
radiator temperature
6:
Compressor frequency restriction by
Discharge temperature
7:
Compressor frequency restriction by pressure
6 T3: Condenser temperature (°C)

When no decimal point is displayed:
Temperature is ≥ ‐9°C
Actual value = value displayed


When decimal point is displayed between the two digits:
Temperature is ≤ ‐10°C
Actual value = value displayed x ‐10
Example: “1.2” indicates ‐12°C
7 T4: Outdoor ambient temperature (°C)
8 Tp: Discharge temperature (°C)
When the temperature < 100 °C, actual value = value displayed. When the
temperature
≥
100 °C, actual value = value displayed × 10
9 Th: Suction temperature (°C)
