He mentioned the EPlus developer's guide. I wonder he has the Eplus source code to compare.
The names mentioned in the error message are the module internal variable name. I do not know the detail of the calculation.
I know that when the RH value is larger than 100%, the calculated temperature can go out of range.
Therefore, you can try increasing the cooling coil temperature, or reducing the wet-bulb temperature of OA to see whether the warning would disappear. These warnings did not stop the simmulation, and the results are still good.
You have 5 or 6 AHU's, timestep = 20, many zones. That is why you get more than 279556 warnings of the same type.
You have other problems in your IDF which prevent the temperature in the zones to be proerly controlled. Because I have not figured out how you named the zones, it will take some time to get an over all view of your design.
You seems to have two buildings (CD and OFF), one three storeys and one five stories. You have cooling chiller, but no heating plant equipment. AHU provideds the cooling to a low temperature and then heated b the reheat heater in the zone. The reheat heater is also used for Winter heating.
The reheat coil can be used for humidity control with cooling in Summer and heating in Winter. I have not checked your schedules, etc.
The VAV damper setting, if reversed, would also caused the zone temperature control to fail.
You should look at the other warning vessages to fix the problems.
