Mitsubishi Electronics TG-2000A operation manual Watt Hour Meter Data Maintenance

3)When the integration has already been made, select Recalculation to settle the charge for the month concerned.

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.

<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.	Watt Hour Meter Maintenance screen
2)	Select the watt hour meter data.	[Watt Hour Meter Data Display Colors]
	Select the cell of the data to be changed (regular hours,

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.
