● Users can choose from 4 low
noise levels, depending on the
installation environment.
If all the indoor and outdoor units are
changed to economy mode, this can save
more energy than setting of each indoor
unit individually.
Economy operation is energy saving, as
the set temperature of indoor unit is shifted
by 2°F (1°C) and the maximum electric
value of the outdoor unit is suppressed.
● Operation setting can be changed
4 times in each day of a week, and
2types of the schedule can be set
to suit users' preference.
