1-1 Outdoor coil temperature
To obtain data on the outdoor coil temperature,
add the number of bits of lighting LEDs, and
see the graph to find the temperature.
1-2 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.
1-3 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.
1-4 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 during normal operation. operation will continue.
● The latest check code is indicated.
