I want to use Coil:Cooling:WaterToAirHeatPump:EquationFit in a normal air loop i.e. AirLoopHVAC. I entered the Coil:Cooling:WaterToAirHeatPump:EquationFit object in Branch, and I got the following severe error.

   ** Severe  ** GetAirPathData: AirLoopHVAC = "CRAH".
   **   ~~~   ** ..Invalid Air Loop Component Type = "COIL:COOLING:WATERTOAIRHEATPUMP:EQUATIONFIT".
   **   ~~~   ** ..Air Loop Component Name = "DX COOLING COIL".
   **   ~~~   ** ..reference Branch = "CRAH MAIN BRANCH".
   **  Fatal  ** GetAirPathData: Errors found retrieving input for AirLoopHVAC.
   ...Summary of Errors that led to program termination:

IDF Editor shows the object in a drop-down list in Branch, so I thought we can use it, but the error says it is invalid.

When I check ExampleFiles, Coil:Cooling:WaterToAirHeatPump:XXX object is always used with AirLoopHVAC:UnitaryHeatPump:waterToAir. Do we have to use Coil:Cooling:WaterToAirHeatPump:XXX with AirLoopHVAC:UnitaryHeatPump:waterToAir? I don't want to use AirLoopHVAC:UnitaryHeatPump:waterToAir because it allows Fan:OnOff only. My system is variable air flow. Is there any way to use Coil:Cooling:WaterToAirHeatPump:XXX without AirLoopHVAC:UnitaryHeatPump:waterToAir?

I want to use Coil:Cooling:WaterToAirHeatPump:EquationFit in a normal air loop i.e. AirLoopHVAC. I entered the Coil:Cooling:WaterToAirHeatPump:EquationFit object in Branch, and I got the following severe error.error. EnergyPlus is V24-1-0.
