Winter months issue - southern hemisphere

edit

I've run an openstudio simulation for a family house in the southern hemisphere (Punta Arenas, Chile) and on both "District Heating Consumption" table and "District Peaking Heat Demand" the winter months (from June to September) are calculated as summer months, like northern hemisphere weather. This problem only appears on these months, as the rest of the year is calculated as it should.

I couldn't find the problem so I checked the weather file I used from the Energyplus website on both Excel and Climate Consultant and it looked everything was right with the epw file.

Does anyone know what should I do on openstudio to correct this? Am I missing anything?

Thanks in advance!
