● Outdoor Unit Setting
To proceed with the Capacity control in [Schedule] [External input], select the desired Outdoor unit in [Settings] then
[Outdoor unit] and check [Capacity].
[Outdoor unit Capacity] is a function to save by the closest designated percent the Power consumption regarding the
cooling rated power amount.
The setting will be applied within 15 minutes after being set.
Even if the Capacity control is proceeded at 0%, the Power consumption will not be 0 because the Standby Power* is
generated.
If the Outdoor unit is in Startup Control or during defrosting, it will be excluded from this Control.
This Control does not ensure the Power consumption as in the setting.
* The Standby Power is a Power amount that is used to prepare for the next operation when the Air Conditioner is stopped.
When performing Lower Noise in [Schedule] [External input], select the desired Outdoor unit in [Settings] [Outdoor unit]
and check [Capacity] then [Lower noise].
If the Outdoor unit which does not support [Lower noise] function is set by [Lower noise], be careful because the
[Capacity] function may not operate correctly.
When the option for [Low noise] is applied simultaneously with the option for [Capacity], only the [Low noise] option will
operate correctly.
