9.2Maintenance of Charge Data

It is possible to change or correct the proportional division parameter, which is the proportionally divided value data of the unit, or the apportioned electric power and electric power amount of WHM every day.

9.2.1 Preparing for Charging Data Maintenance

Prepare and perform the following for charging data maintenance:

(1)Maintenance object and date check

Check the object indoor unit and date whose proportional division parameter or apportioned electric power, etc. you want to correct due to a failure.

Check by referring to the failure recovery data and charging data display color (normal, abnormal, maintenance), system configuration, etc.

(2)Reference data preparation

Prepare the normal apportioning data and indoor unit FAN operation amount, capacity save ratio, and other data.

*The FAN operation amount, capacity save ratio, and indoor unit operation performance, FAN capacity, subsidiary heater capacity can be displayed on “Maintenance of chargedata”screen.

(3)Correction charge data study

Study the maintenance object indoor unit, interval (date) and charging data correction value from (1) and (2) above.

At the end of the preparations above, perform charging data maintenance.

Note:

For the charging data result (normal, abnormal, maintenance), refer to section “9.2.3 Unit Data Maintenance”.

The contents will appear in the air-conditioning charge after recalculation at the end of charging data maintenance.

The “subsidiary heater time” value is not used. The “subsidiary heater capacity” value is always dealt with as 0, because there is no indoor unit with a subsidiary heater.

9.2.2 Maintenance Methods and Restrictions

Follow these steps to display the Charge Data Mainte- nance screen.

1)Click [Maintenance of charge data] button. From the Initial window, click the [Maintenance of charge data] button in the Maintenance group. The Charge Data Maintenance screen appears.

Note:

The items that can be changed in this screen are the proportional division parameters of indoor units. The parameters of indoor units and outdoor units can be performed the maintenance separately.

Charge Data can be stored for up to 62 days excluding the present day.
