*1: Can be calculated for each charging block. May not be available with some older models.
*2: Indoor unit models before Free Plan models do not support a charge apportioning billing method based on the
“capacity save.” The existence of even a single unit of those types in the system requires that the method of
charge apportioning billing be set to either “Thermo on time” or “Fan operation time.”
Certain restrictions apply to large-capacity indoor units when malfunctions occur.
*3: LOSSNAY groups to which the remote controller is connected support the charging system.
*4: Not all of the A-control and K-control units support these functions. (e.g., The calculation of the charge for the
auxiliary heater may not be handled by these units.)
*5: Outdoor unit capacity control function is not available.
*6: Only the function to stop the units is available.
*7: When the attribute is IC (indoor unit): Same type of energy-save control unit as with the Freeplan Indoor unit is
possible.
When the attribute is FU (LOSSNAY with a heater/humidifier): no direct energy-save control is possible.
*8: Inverter models support the outdoor unit capacity save control function.
*9: Outdoor unit Thermo-OFF control function is not supported. Only the fan control function is available.
*10: Only the temperature control function or the function to stop the units is available.
