[Equest-users] BDL Error

[Chris Jones]

The Split system single is PSZ, or PTAC or UH but these systems are 
the same in that the first zone on the system cannot be unconditioned 
unless another, conditioned zone is explicitly defined as the CONTROL-ZONE.

Did you intend that each zone have a single system serving it?  Are 
the spaces to be heated some other way or are the spaces ventilated only?

It would be helpful if you could explain the proposed design HVAC 
configuration.
