After running the simulation for a residential building served by water source heat pumps in OpenStudio, the EnergyPlus error file showed the below warnings. I tried to find the "Water flow rate ratio" in the input/output documentation of E+, but no luck, I checked the input for the range and approach temperature they were as designed. I am not sure what is triggering these warnings. I am guessing the reason for the last three warnings is the sizing in a heating design day. Thank you!

Can you paste the IDF snippet for your Cooling Tower Variable Speed 1, as well as any related CoolingTowerPerformance:XXXX object? Just trying to see which model you're indeed using and what parameters you have input that could affect it. In case you use YorkCalcs or CoolTools, the boundaries are harcoded and different.

@Julien Marrec I added the Cooling Tower snippet to the question above. I used the default variable speed cooling tower available in OpenStudio v2.6.
