[EnergyPlus_Support] Unitary MultiSpeed Heat Pump

Hello.

I'm trying to get a Unitary MultiSpeed Heat Pump to work (serving a 
single zone, all other zones have PA, which were already working 
before introducing the MSHP), but I keep getting node connection 
errors and I can't track down where they come from. Could anyone help 
figure out where to look?

The errors are as follows:

   ** Severe  ** SET POINT MANAGER:SINGLE ZONE REHEAT: Controlled 
Zone not on air loop, Zone=47833
   **   ~~~   ** Occurs in Set Point Manager=ROOFTOP AHU SUPPLY AIR 
TEMP MANAGER
   **  Fatal  ** Errors found in SetPointManager input
   ...Summary of Errors that led to program termination:
   ..... Reference severe error count=1
   ..... Last severe error=SET POINT MANAGER:SINGLE ZONE REHEAT: 
Controlled Zone not on air loop, Zone=47833
   ************* Fatal error -- final processing.  More error 
messages may appear.
   ************* Testing Individual Branch Integrity
   ** Warning ** There are orphaned Branches in input
