New construction project where there will be multiple radiant heat zones, and a limited number of those zones will also have heat pump FAU, and they say they want to use both the radiant AND the heat from the FAU together in those zones. How do we set that up on a single T-STAT and controller? Would the FAU heat be considered 2nd stage heat? Is there more documentation, (I have downloaded everything I can find) that goes into the setup for this in the software?
