z Outdoor unit capacity save function
„
The Input Power is reduced by limiting the upper limit of the outdoor unit capacity for each
refrigerant system.
This has an energy saving effect, especially in the summer, winter and other times when the
heat load is high.
In addition, because the upper limit capacity of the outdoor unit is limited directly, it is a control
which easily exhibits an energy saving effect compared to rotation control. However, because
the outdoor unit does not operate above the limited capacity, there may be a loss of comfort,
depending on the indoor heat load.
* The operation capacity upper limit rate [%] of the outdoor unit is specified for each refrigerant
system.
