c . Check to see if the total of the division results of all the indoor units matches the total of the watt hour meter.

Because division errors occur, a difference less than (the number of blocks × 0.1) kWh is deemed OK.

If the difference exceeds (the number of blocks × 0.1) kWh then check the following settings and rectify the problem.

Charge block setting (block setting)

Outdoor unit to watt hour meter relationship

Indoor unit to watt hour meter relationship

d.Check that the standard charge portion is included in the block settlement amount of the settlement results.

Block settlement amount = (total of block indoor units division electric amount totals) × charge unit + standard charge

Because settlement errors occur, a difference less than number of blocks × minimum exchange unit is deemed OK.

When the difference exceeds (number of blocks × minimum exchange unit) then check the following settings and rectify the problem.

Charge block setting (block setting)

Standard charge setting

Note:

Only judgment standard d can be recalculated and rechecked.

Maintenance Tip:

After the charging test run check, check the result of the print out of the settlement day calculation for day 1.

If the system is modified, always check the calculation results of the next settlement day or one day after the change and 10 days after the change.

To make the check sheets easy to read, allocate 1 check sheet page for each installation floor unit or G-50A unit.
