Encog 3 java time series forecast read from CSV

I am developing a system for forecasting time series. I bought the Encog3 book for Java, but I need to know what it takes to send a CSV file with 3 columns and try to predict the second column. CSV is defined as follows:

Date, DeviceConsumption,TotalPower

I need to load this file into the loader and specify the column that I want to predict (this DeviceConsumption). The third column is used to provide additional information and create a template.

In examples (e.g. sunspots) I see

TemporalMLDataSet result = new TemporalMLDataSet(windowSize,1);
TemporalDataDescription desc = new TemporalDataDescription(new ActivationSIN(),Type.RAW, false, true);

result.addDescription(desc);

but where can I identify the column that I want to predict?

Thank.

EDIT 2 I have made several improvements:

, . 2 TemporalDataDescription, . TemporalMLDataSet?

TemporalMLDataSet result = new TemporalMLDataSet(WINDOW_SIZE,1);
TemporalDataDescription desc = new TemporalDataDescription(
TemporalDataDescription.Type.RAW,true,true);
    result.addDescription(desc);
TemporalDataDescription desc2 = new TemporalDataDescription(
TemporalDataDescription.Type.RAW,false,true);
    result.addDescription(desc2);

    for(int year = TRAIN_START;year<TRAIN_END;year++)
    {
        TemporalPoint point = new TemporalPoint(2);
        point.setSequence(year);
        point.setData(0, this.deviceConsumption[year]);
        point.setData(1, this.TotalPower[year]);
        result.getPoints().add(point);

    }
    result.generate();

?
