6) Repeat steps 1) to 5), and change all the indoor units.
Repeat these steps to make changes to the apportioned data value to be changed.
7) Click [OK] button.
When done with these settings, click the [OK] button.

<Maintenance example>
Example of “Maintenance of charge data” during G-50A failure (proportionally divided electric power
charge (Without WHM connection))
1) Correct the proportional division parameter (during failure) to “0”, by which the value is changed to
blue.
* Including appointed day of repair
2) Select and correct the failure period correction method from the following plans.
Plan (1): Use of average value for one week before failure
Calculate the proportional division parameter (given by multiplying the number of
days of the failure period using the average value for one week before failure as the
proportional division parameter for a day, and input it as a proportional division
parameter for the repair date.
Plan (2): Use of normal period only
Use the proportional division parameter only for the normal period, but not the
proportional division parameter for the number of all indoor units used during the
failure period. Correct the proportional division parameter for all indoor units during
the failure period to “0”.
Not e:
• If the apportioned data of the unit (proportional division parameter value and apportioned electric
power) is corrected, the value is reflected in air-conditioning charge when it is recalculated.
The data for that day may not be correct if there was an abnormality on the previous day. (For
example, when the previous day was abnormal, it may be forwarded to the next day.)
• The proportional division parameter displayed in red is changed to maintenance (blue) and
recalculated and appears in the air-conditioning charge results. (It is, however, necessary to
perform maintenance for all abnormal color (red), no data color (gray), and un-apportioned data
color (green) located within the air-conditioning charge settlement period.)
• When the outdoor unit apportioning mode is 2, the crank case heater apportioned electric power
also changes.
