9.1 Result of Air-conditioning Charge Calculation
Air-conditioning charge calculation by the proportionally divided power charge function is based on the
indoor unit operation amount data. When data cannot be collected and calculation is unmatched for
some reason, irregular processing is performed. “Maintenance of charge data” and “Remedial
apportioning setting” may be necessary depending on the contents of this irregular processing.
The table below shows assumed cases.

* 1 : For repair, the operation amount for the repair period is monitored to output the CSV file upon the
output of the charge parameter. The proportional division parameter is found by calculating it from
the values of the difference and the capacity. The parameter is input through the charge data
maintenance, by which the charge data can be repaired.
*2: When a forwarding that extends past the settlement-of-accounts day occurs, it is recommended to
correct it in the “Charge data maintenance” screen. It is unnecessary to perform this procedure when
there is an agreement that allows the charge to be collected, even if the forwarded settlement occurs.

Note:
• If there are two or more assumed cases, make overall judgment.
• When forwarding of apportionment spans the settlement -of-accounts day, the forwarded portion is
added to the next month. When you want to separate this month’s portion and next month’s portion,
divide the proportion division parameter forwarded and collected by “Charge data maintenance”
screen by the number of days in next month and this month.
• The charge data status is irregularly processed according to the case which occurred.
