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 indecated 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
●
When a protection function works for the first time during operation, the operation stops and restarts after the 3-minutes
time delay mode. When the protection function works again, the operation stops. (Check mode) When both SW3-1 and
SW3-2 are OFF, the check code is indicated.
●
If the outdoor controller board receives the compressor ON command from the indoor controller board during check
mode the indication changes to output state indication.
●
By pressing SW2 duirng normal operation. operation will continue.
●
The latest check code is indicated.
