Sounds good so far. Make sure you select "System per Zone" for the PTAC

Subject: [Equest-users] Properly modeling PTAC and Baseboard system
Hi everyone,
I have a (hopefully simple) question on how to model a senior living
center HVAC system.  Central natural gas boiler provide heating which is
delivered through baseboards and cooling is provided by through-wall AC
units (one per each apartment).
I've modeled the system as Cooling: DX coils; Heating: None; System
Type: PTAC (no heating).  I'm currently in the DD Wizard so on Wizard
Screen 6 I've selected Baseboard source as Hot Water Loop.
I'm hoping that someone can confirm this is the correct way to model
this system.
Thanks very much.
