Re: [EnergyPlus_Support] Re: Output error
The solution depends on what you want as your result. If you want
results for an uncontrolled space, then I'd say you have the answer.
Disregard the warning because you know why it is being reported (high
indoor RH).
Since you have used this weather file before, something must have
changed. What did you change to make the warning show up?
What would you like to happen?
