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. </div><div style="position:fixed"></div>
