Unitary system not meeting cooling load

Hi everyone, I'm using energyplus dan I have a problem when using unitary system template. I see just 0,00 at cooling load, calculated and user design load at output result. I'm not using for heating, just for cooling and cooling setpoint is 24C. Please see my attachment file. What should I change in idf file in order to get cooling load at the output result?

Add these report variables to your simulation.

Output:Variable,*,Zone Air Temperature,hourly; !- HVAC Average [C]
Output:Variable,*,Zone Predicted Sensible Load to Cooling Setpoint Heat Transfer Rate,hourly; !- HVAC Average [W]

The results only show a heating load (for Brisbane AUS but I assume the same is true for your weather). Also, the zones named Thermal Zone X show a 0, I think this means there is no thermostat. You also have many warnings in the err file that should be addressed.
