[EnergyPlus_Support] 4-Pipe Induction Unit's cooling coil sizing error

Hi all,

I tried to replace a VAV with Reheat to a 4-pipe induction unit.  To achieve this, I created a Coil:Cooling:Water object, a branch, included the coil in the branch list, zone mixer and splitter, and a zone mixer.

However, I keep getting a severe error saying that my cooling coil is not on any plant loop and thus cannot be autosized.  

 ** Warning ** Could not find chilled water coil with name L3:ENPATRM COOLING COIL on any plant loop
   **   ~~~   ** Autosizing of water coil requires a cooling loop Sizing:Plant object
   **   ~~~   ** Occurs in water coil object= L3:ENPATRM COOLING COIL
   **  Fatal  ** Preceeding water coil sizing errors cause program termination


How is this suppose to work?  I had a few cooling coils for my AHUs and heating coil @ my terminal VAVs as reheat, and the model runs fine.  

Any advice would be greatly appreciated!
