Hello, I'm modeling water to air heat pump in open studio but even though I can see the nodes in the loop tab, simulation gives error like following: * Severe * IP: IDF line~121718 Error detected in Object=COIL:COOLING:WATERTOAIRHEATPUMP:EQUATIONFIT, name=WTR-TO-AIR HP CLG COIL 60 * ~~~ * Field [Water Inlet Node Name] is required but was blank *** IDF Context for following error/warning message: *** Note -- lines truncated at 300 characters, if necessary... *** 121716 Coil:Cooling:WaterToAirHeatPump:EquationFit, *** indicated Name=Wtr-to-Air HP Clg Coil 60 *** Only last 3 lines before error line shown..... *** 121717 Wtr-to-Air HP Clg Coil 60, !- Name *** 121718 , !- Water Inlet Node Name *** 121719 , !- Water Outlet Node Name
Also I have a fatal error which is: * Severe * IP: Possible incorrect IDD File * ~~~ * IDD Version:"IDD_Version 8.4.0" * ~~~ * Version in IDF="8.4" not the same as expected="8.4" * ~~~ * Possible Invalid Numerics or other problems * Fatal * IP: Errors occurred on processing IDF file. Preceding condition(s) cause termination.
Does anyone encounter this type of error before?
Thank you Elvin
