I would recommend going with PSZ and using the Detailed Edit mode in eQUEST to create a system for every zone. If this is cumbersome, you could also go back to the eQUEST wizard mode and create a PSZ system and assign it to every zone. In the HVAC System Wizard, this is done by choosing System Type: Packaged Single Zone DX and System per Area: System per Zone. The PSZ system type is more flexible than the PTAC system type and allows you to use a wider range of options for heating and cooling. It is also the system type used in the Daikin VRF Guide.
This sounds very odd. One would expect the heating energy to be lower with a heat pump (which typically uses electric heat as a backup when the heat pump can't provide enough heat). I just tried creating a model in the wizard, and switched the heating type from heat pump to electric for a PTAC and the heating energy went up as expected. Can you provide any more information about your model? What is the climate zone? Do you have unmet heating hours? What is the Heating Electric Input Ratio for your heat pumps?
