[BLDG-SIM] eQUEST-System no heating

[Zhen Tian]

Dear All,
   
  I experienced an issue when I use eQUEST. I model a building in cold climate with VAV system. In the wizard mode, I found the system heat source is "not installed". But when I change to electricity, I found the heating enery use for system heating is zero. I also tried other options, always found that the system heat source is useless. I found that all the heating goes the zone level. Based on my understanding, this should not be the real case.
   
  I set the air supply temperature as constant as 55F (around 13 degree C), zone entering max air tem as 95F. Enen I set the zone entering max air tem as 86 (30 C). The system heating coil still has no load.
   
  Has anyone experience the same problem before and know to to solve this problem?
   
  Thanks a lot.
   
  Regards,
   
  David
