How to create air loop for FourPipeFanCoil model?

Hello,

I want to model a fan coil unit with FourPipeFanCoil library model. I add this model to the thermal zone equipment and select heating and cooling water coils for it. (below picture)

after I ran the simulation, the below errors are generated because of missing inlet and outlet air nodes of heating and cooling coils.

Program Version,EnergyPlus, Version 22.2.0-aa78da9668, YMD=2023.10.06 21:11,

** Severe ** <root>[Coil:Cooling:Water][Fan Coil with Var Fan Var Fluid Flow - Cooling Coil] - Missing required property 'air_inlet_node_name'.

** Severe ** <root>[Coil:Cooling:Water][Fan Coil with Var Fan Var Fluid Flow - Cooling Coil] - Missing required property 'air_outlet_node_name'.

** Severe ** <root>[Coil:Heating:Water][Fan Coil with Var Fan Var Fluid Flow - Heating Coil] - Missing required property 'air_inlet_node_name'.

** Severe ** <root>[Coil:Heating:Water][Fan Coil with Var Fan Var Fluid Flow - Heating Coil] - Missing required property 'air_outlet_node_name'.

** Fatal ** Errors occurred on processing input file. Preceding condition(s) cause termination.

I want to create an airloop to fix the above errors. However, I can't add heating and cooling coils of the fan coil unit to the air loop. (below picture)
