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)

Could you please help me to fix this problem?

Hello, did you get this problem fixed? I had the same problem with my Chiller, Fan Coil system setup.

@sh sadegh you have to put the coil in the thermal zone and then link with the correspondent plant loop.

Hello, I've got the zone equipment (Fan/Coil) linked to the Chiller/Hot water loop correctly. But cannot add Fan/Coil unit to an air loop.
