[EnergyPlus_Support] Re: Error in Electrical Chiller Simulation

["energypluser" <energypluser@xxxxxxxxxxxx>]

Dear Mike
      I found out the wrong setup in the object:"plant-condenser 
loops" which causes the unnormal mass flow rate through the loop. 
And I think that is not necessary to upload the file.
      Thank you for your help!
