Used for service diagnosis of DC compressor. Since the
waveform of inverter is output without wiring to the
compressor, it is convenient to probe whether the trouble
comes from the compressor or PCB.
Changes target value of power consumption when demand
control 1 is input.
Normally enables demand control 1 without external input.
(Effective to prevent a problem that circuit breaker of small
capacity is shut down due to large load.)
Used to temporarily prohibit the applicable condensing unit
from operating should there be any defective part in multi
condensing unit system. Since the comfortable environment
is extremely impaired, prompt replacement of the part is
required.
