(2)Check the meter values of the watt hour meter (No. 1)

Check the name and the meter value of all the watt hour meters connected to RS-485 and write them down on the charging test run check sheet.

(The integrated value of the watt hour meter can be monitored by using the function “Management of charge data”. For details, see section 9.2.5)

Note:

Perform this on the day after the charging setting details on the man-machine console were checked.

(3)Let the air conditioner run

Operate all the air conditioners from the man-machine console (TG -2000A).

Check that all air conditioners are running and write it down on the charging test run check sheet.

Note:

You must run all air conditioner units for longer than 2 hours.

(When they do not run for that length of time, the results will not pass the judgment standards outlined in (6) Judgment standards.)

(4)Check the meter values of the watt hour meter (No. 2)

After the air conditioners running operation is complete, check the name and the meter value of all the watt hour meters connected to RS-485 and write them down on the charging test run check sheet.

Note:

Check that the measured meter value is larger than the value measured at step (2) above. If the values are the same, operate the air conditioner again for at least 2 hours. (It is recommended that test run be performed with the local remote controller and centralized controller.)

(5)Check the results of charging division

Check the following on the charge data maintenance screen and write them down on the charging test run check sheet.

Note:

Perform this on the day after the air conditioner running operation (charging test run).

(6)Check the settlement results

Perform this two days after the charging test run. You should either print the settlement results or export them to a file.

(The settlement is carried out later than 05:10 on the day after the settlement day.)

(7)Judgment standards

With WHM connection: Check a ~ d.

a.Check that the electric amount of the watt hour meter (within-outside) is not “0”. If the electric amount (within-outside) is not “0” then that is deemed OK.

If the electric amount is “0”, check the following details and rectify the problem.

Check if the meter value of the watt hour meter check increased by more than 1kWh from No. 1 to No. 2.

If the value did not increase, redo the watt hour meter check and also redo the running operation of the air conditioners.

Check the transmission cable connection between the RS-232C of the PC and the watt hour meter.

b.Check that the division result (within-outside) is not “0”.

If the electric amount (within-outside) is not “0”, then that is deemed OK.

If the electric amount is “0”, check the following details and rectify the problem.

Indoor unit performance

Indoor unit fan capacity

FAN operation time and the capacity saving amount on the charge data maintenace screen.
