I have created an WaterHeater:Stratified object, and it has a source side. The source side inlet temperature may be lower than the water heater tank temperature because of electricity heater 1 and 2, and I want to ensure the source side inlet mass flow rate to be 0 when the water tank temperature get higher than the source side inlet temperature. So I filled in the field Source side Flow Control Mode with indirectHeatAlternateSetpoint, and created an indirect alternate setpoint temperature schedule, hoping to control the source side flow, but it didn't work. The source side still flows into the Water Heater even when the Water Tank Temperature is higher, which doesn't make sense.
Anyone can help me ? Thanks very much!
