Re: [EnergyPlus_Support] Other Error


1.  Have you autosized the controller convergence tolerance?

2.  Does the HVAC system draw completely (svg output file)?  If not, there is 
probably a node connection error somewhere.

3.  The "no valid range" warning indicates that the demand on the chilled water 
loop exceeds the highest load range specified in the Load Range Based Operation 
Scheme named "CHILLER:ELECTRIC".  Check the load ranges and increase the limit 
on the highest one to be something greater than 330753.
