Case Examples
(1) A value on a wattmeter of each outdoor unit system does not correspond to PPD result.
Electric power of wattmeter A is nearly the same as that of wattmeters B + C + D.
However, the PPD result of outdoor unit system 1 (4 indoor units) does not correspond to the value on wattmeter B.
[Reason]
An intersystem difference causes this problem.
The PPD function does not recognize how many outdoor units exist in an electric power group. It regards outdoor units as one big unit
to perform PPD calculation.
[Countermeasure]
If each outdoor unit system has a watthour meter, make a power group for each outdoor unit system.
