3) When the integration has already been made, select Recalculation to settle the charge for the
month concerned.
<Maintenance example>
Example of “Maintenance of charge data” during G-50A failure (proportionally divided electric power
charge (With RS-485 WHM connection))
1) Correct the apportioned electric power (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 : Use of average value for one week before failure
Calculate the power used during the failure period proportionally by percentage
using the average value for one week before the failure as the apportioned electric
power for a day, and input it as apportioned electric power for the repair date.
3) When the integration has already been made, select Recalculation to settle the charge for the
month concerned.
9.2.4 Watt Hour Meter Data Maintenance
This data may be changed. Follow these steps to display watt hour meter data broken down by regular
hours and off hours.
Maintaining watt hour Meter Data
[Procedure]
1) Click the “ ” button and select a watt hour meter.
When the “ ” button in the watt hour meter field in the
charging data maintenance screen is clicked, all the watt
hour meters are displayed. Selecting the watt hour meter
you want to display and clicking the [Meter Maintenance]
button displays the watt hour meter maintenance screen.
2) Select the watt hour meter data.
Select the cell of the data to be changed (regular hours,
off hours). The cursor appears in that cell.
3) Make changes to the data.
Enter the changes to the data (for each time slot).
4) Repeat steps 1) to 3).
Repeat these steps to make changes to the part to be
changed.
5) Click [OK] button.
When done with these settings, click the [OK] button.
* If the [Cancel] button is clicked, the settings are interrupted and the screen returns to the initial
window.
Note:
• It is necessary to perform the charge data maintenance on the date appointed for G-50A
repair, after the next day, when the G-50A is replaced.
• Since the data cannot be fully corrected when the G-50A is replaced, it is necessary to
perform a special correction during failure.
Note:
• Corrected watt hour meter data will appear in the air-conditioning charge after recalculation.
However, only watt hour units’ watt hour meters are the object. The corrected watt hour meter data
does not appear at indoor units or watt hour meters connected to indoor units.
• 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 electric power displayed in red is changed to maintenance (blue) and
recalculated and appears in the air-conditioning charge results. (However, all the electric power
displayed in red in the air-conditioning charge settlement-of-accounts term must be maintained.)
• This function cannot be used for Without WHM connection proportionally divided electric charge.
