How to resolve gross_rated_sensible_heat_ratio error of EnergyPlus measures in OpenStudio

Hello to the entire community,

I have modeled Split air conditioner in a single zone using OpenStudio. I downloaded the fault models from the NREL site to analyze their impact.

For cases using "EnergyPlus measures" (like condenser fouling, PresenceOfNonCondensable, LiquidLineRestriction), the simulation has failed, and eplusout.err displays the following error:

<root>[Coil:Cooling:DX:SingleSpeed][1 Spd DX Clg Coil 7][gross_rated_sensible_heat_ratio] - Value type "string" for input "NaN" not permitted by 'type' constraint. Failed to validate against child schema #0, "NaN" - Failed to match against any enum values. Failed to validate against any schemas allowed by the anyOf constraint.

I defined the rated_sensible_heat_ratio value as 0.75, but the error persists.

I changed the value of rated sensible heat ratio to 0.75 in the 1 Spd DX Clg Coil 7 but the error remains the same.

Can you link to the measures you’re using? It’s impossible to help with the information you’ve provided.

I am using BCL measures

Thanks. Can you also attach your OpenStudio model (before applying the measure) via something like Dropbox or Google Drive?
