Equation Fit Water-to-air Heat Pump Object in OpenStudio

Hello, I would like to know if there is a way to implement the Coil:WaterToAirHeatPump:EquationFit Energy Plus object within an Airloop in OpenStudio.

I've succeded in extracting the object from the AirLoopHVAC:UnitaryHeatPump:WaterToAir object source code and inserting it into an AirLoop, but I get severe errors stating that the componenet type is invalid ''..Invalid Air Loop Component Type = "COIL:HEATING:WATERTOAIRHEATPUMP:EQUATIONFIT"

The water-to-air unitary heat pump accessible through OpenStudio contains cooling, heating and electric coil; however, the packaged unit I am trying to model only contains a heating coil.

Is there a way to fix the severe error or is there any simpler ways of inserting an equation fit, water-to-air heat pump model in an OpenStudio AirLoop?

Thanks.
