I am working on modeling an open loop geothermal heat pump in E+ and am having issues with my water temperature. I have read one post about how to model an open loop system by using PlantComponent:TemeratureSource which is what I used for model. I specify a PlantComponent:TemperatureSource with a constant temperature of 47 F (local deep ground water temperature). I have coupled this with setpointmanager:scheduled (which is a schedule of 47 F for all days) and PlantEquipmentOperation:Uncontrolled. When I run my model and look at the CondenserLoopDemandReport:Monthly, the report is indicating a loop supply temperature of -37 C (~ -35 F) which is WAY too low. Any thoughts on why this is happening and how I might be able to fix it?
