Description
Issue overview
I tried to hard sized WaterHeater:HeatPump:PumpedCondenser object but still get bypass factor Psychrometric function calculation error. There is similar issue (#8412) but it's Stratified Tank object. Not sure if WaterHeater:HeatPump:PumpedCondenser/Coil:WaterHeating:AirToWaterHeatPump:Pumped have same issue - The error log did not point to particular object. Did turn off sizing option in simulation control but keeps fail

Done means the failing object and reproducible error are identified clearly enough to guide a fix.
