Re: [EnergyPlus_Support] regeneration coil

Did you "list" the HW coil type and name in the Outside Air System object?
You would also want the HW coil to turn on only when the desiccant 
system is on. The only way I can think of is to manually create an 
availability schedule for the HW coil based on the times when the 
desiccant system operates.
