I would like to get the output values of VRF performnance curves for validation purpose.

I tested with an ExampleFile VariableRefrigerantFlow_5Zone.idf (V25-2-0). The output values of the following curves are -999 throughout the year, which indicates the curves are inactive or unused.

1. Cooling Combination Ratio Correction Factor Curve
2. Piping Correction Factor for Length in Cooling Mode Curve

FYI, the Output:Variable settings are as follows.

Output:Variable,
    COOLINGCOMBRATIO,        !- Key Value
    Performance Curve Output Value ,  !- Variable Name
    Hourly;                  !- Reporting Frequency

Output:Variable,
    CoolingLengthCorrectionFactor,  !- Key Value
    Performance Curve Output Value ,  !- Variable Name
    Hourly;                  !- Reporting Frequency

For 1, it will not be used when CR is less than 1. I reduced the heat pump's Gross Rated Total Cooling Capacity by hardsizing it, but I still got -999.

For 2, I changed the performance curve coefficients, and the cooling energy use changed. So, the curve is actualy used.

I tested all types of Reporting Frequency, but in vain.

How can I get the output of the two curves?
