Energyplus water heater sizing -99999.0

image description

In the energyplus html report, I noticed that the Equipment Summary section reports Input for service water heating as "-99999.0". What does this mean?

The water heater is modeled as autosized. But in other models that I have water heater autosized, this report will show an autosized input rate not -99999.0.
