The capacity limit can be selected by the external input terminal (CN133) when
operating with the “Energy Saving Peak Cut function”.
The lower the level, the more the effect of energy saving, but the cooling/heating
performance will also drop.

If the cooling/heating performance becomes insuffi cient when the low noise mode is set,
it is possible to set “capacity priority” that automatically cancels the low noise mode (once
performance is restored, the mode will automatically return to the low noise mode).
