Rooms in System

When you create an HVAC system in CoolCalc Manual J it is often convenient to specify that the system serves all the rooms in the home's conditioned area.

CoolCalc Manual J by default considers that all above grade rooms are heated and cooled, and all below grade rooms are heated only. However, you can edit those settings on the "rooms in system" screen.
