When setting of the remedial apportioning screen is complete, perform Section 9.5.2 “(3)
Calculate remedial apportioning”.
9.5.7 Remedy for system information setting error
The following describes the remedy when a system information (system configuration, charging system,
etc.) setting error was found.
1) System setting error recovery
Find and correct the system setting error. Setting errors include group setting, block setting, watt hour
meter and unit correspondence setting, etc.
2) Continue operation until the day after the settlement -of-accounts day .
Continue normal operation up to the day after the settlement -of-accounts day.
3) Start remedial apportioning.
Start remedial apportioning by clicking the [Remedial apportioning] button in the initial window. This is
described by the time series example below.
Note:
• It may not be possible to remedy a setting error even by remedial apportioning depending on the
type of system setting error.
• This remedial apportioning cannot be used for system configuration and other changes.
N o t e :
• Normal operation is continued up to the day after the settlement -of-accounts day because
remedial apportioning is performed for one month.
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.)
Maintenance tip
• Before system setting error recovery, perform interval settlement -of-accounts up to the day
before the setting error and output the result.
Note:
• The watt hour meter integrated value for each date can be displayed by integrated value by
changing the remedial apportioning start day.
• The day before the failure day must be charge apportioned normally.
• The indoor unit operation amount can also be referenced in watt hour meter integrated value
calculation and study. The average value can also be studied from the monthly units watt hour
meter air-conditioning charge result. It is recommended that the calculation method suited to the
system conditions be used.
• When the calculated watt hour meter integrated value is a negative value, set the value calculated
integrated value + watt hour meter maximum integrated value + minimum integrated value.
