Hi All,

I accidently set a multiple setpoint managers in EnergyPlus. (SetpointManager:OutdoorAirReset, SetpointManager:Scheduled:DualSetpoint) The SPM I need is SetpointManager:Scheduled:DualSetpoint, not SetpointManager:OutdoorAirReset)

I understand from the reference that the one that comes later in IDF (which is SetpointManager:OutdoorAirReset in this case) overwrites the previous one.

But I set the plant loop demand calculation scheme to be 'DualSetpointDeadband', and in this regard, the simulation terminates without SetpointManager:Scheduled:DualSetpoint.

In this case, I wonder (or I'd like to make sure) if this would enable SetpointManager:Scheduled:DualSetpoint, not SetpointManager:OutdoorAirReset.

The results show that the temperature is well-maintained in between the dual setpoint temperatures. (It doesn't seem that the SetpointManager:OutdoorAirReset overwrote the SetpointManager:Scheduled:DualSetpoint) System Node Setpoint High/Low Temperature on the output:variable seem to be indicating SetpointManager:Scheduled:DualSetpoint as well. But the result with & without SetpointManager:OutdoorAirReset gives out a bit different results.

I sincerely request for your answers. Thank you.
