Hello all,

The selected HVAC system of the proposed model is Packaged Energy Recovery
VAV units with DX cooling, Gas fired heating and electric reheat coil. In
the DD Wizard when I select ?DX Coils? as cooling source and ?furnace? as
heating source, the only option that I have in the System Type window for
selecting the system is ?Packaged Single Zone DX with Furnace?. Then in
Detailed Data Edit mode I can change the selected ?PSZ? system to ?Packaged
Var Vol? but after this change I face a huge number of unmet heating hours
for all zones. Is this process alright or I?m missing something.

Your help would be greatly appreciated.
