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 terminal (CN131).
• 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 terminal (CN132).
The lower the level, the more the effect of energy saving, but the cooling/
heating performance decreases.
