setting
By using the "Low noise mode", the limit of the
noise level will be set to decrease the noise
level. The mode comes in 2 levels which can
be set accordingly.
To turn on the mode, use the external input
connector (P580).
*By using this mode, the cooling/heating
performance may decrease.
*Depending on the operating condition, the
noise level may not decrease even if the Low
noise mode is on.
The capacity limit can be selected when
operating with the Peak cut mode. The
operation selection can be done by external
input connector (PA580).
The lower the level, the more the effect of
energy saving, but the cooling/heating perfor-
mance decreases.
