11) Watt hour meter integrated value setting
The value at 24:00 hours of the day before backup is displayed at the watt hour meter integrated
value of each watt hour meter. The watt hour meter integrated value does not have to be corrected.
When setting of the remedial apportioning screen is complete, perform Section 9.5.2 “(3)
Calculate remedial apportioning”.
9.5.5 Apportioning method when computer crashes
The following describes the apportioning method when the computer crashes and the charging data is
abnormal and apportioning (un-apportioned) cannot be performed.
This is described with the time serial example below.
1) Computer down time chec k
Check the time the computer was shut down at the “Charging data maintenance” screen. When
nothing exists in the charging data, the numbers are displayed in gray.
2) Operation amount backup monitoring
Monitor backup of the operation amount from the day the computer crashed to the day it was recovered.
Set the start day as the computer crash day and the end day as the day before recovery day.
3) Start remedial apportioning.
Start remedial apportioning by clicking the ] Remedial apportioning] button in the initial window.
4) Settlement -of-accounts term setting
Set the settlement-of-accounts term (start day and end
day) at the remedial apportioning setting screen. The
initial value is the settlement-of-accounts term of the
previous month.
5) Total air-conditioning charge setting
Set the settlement -of-accounts term total air-conditioning
charge.
Note:
• “Recovery day” is the day the system was recovered from a HDD failure and is the day
normal operation was restarted.
• When charge is not apportioned normally for the day before the remedial apportioning start
day, change the remedial apportioning start day to the day after the day normally charged
before the backup day.
Note:
• When a value is not displayed in the watt hour meter integrated value field, there is no data in
the database. Since a setting error is possible, check the remedial apportioning start day.
• Normal charge apportioning is necessary for the day before backup.
Note:
• Begin remedial apportioning from the day after the settlement-of-accounts day. However, except
when it is different from the normal settlement -of-accounts term. Remedial apportioning can
begin two days after the recovery day. (Only when the day after the recovery day was normally
charged.)
Note:
• Whether or not un-apportioning of charging data was generated by a computer crash can be
checked at the “Charging data maintenance” screen.
• When the charging data is not apportioned, this remedial apportioning is unnecessary.
Note:
• Operation amount backup monitoring can be performed for the recovery day also.
