[Equest-users] No Heating from PVVT Heat Pump

[Eddie Corwin]

I am trying to model a PVVT system, that uses an air-cooled heat pump for 
heating and cooling.  For some reason, the system refuses to supply any heating. 
 When I change the condenser type from air-cooled to water-cooled, the system 
WILL provide heat.  Has anyone experienced problems like this, or has 
someone successful modeled a PVVT air-cooled heat pump?  I have attached my IDF 
and PD2 file for review.
