3-1 Outdoor coil temperature
To obtain data on the outdoor coil temperature, add the number of bits of lighting LEDs, and see the graph below to find
the temperature.
3-2 Fan output step
To obtain data on the fan output step, add the number of bits of lighting LEDs, and see the graph below to find the fan
rotational frequency.
3-3 Total time of compressor operation
Compressor operation time is indicated in 256 hour units. To obtain the compressor operation time, add the hours of light-
ing LEDs. During the compressor operation time indication, SW2 is not available.
3-4 Check code indication
