'Plant Loop Demand Calculation Scheme' needs to be set when using SetpointManager:Scheduled:DualSetpoint

[adhilton25]

Currently, when the PlantLoop object is translated for a loop that contains SetpointManager:Scheduled:DualSetpoint on the outlet node, the 'Plant Loop Demand Calculation Scheme' field is left blank. This means EnergyPlus defaults to using a 'SingleSetpoint' calculation scheme which doesn't correctly operate the equipment in the loop within the defined deadband.

When a SetpointManager:Scheduled:DualSetpoint is found in the supply outlet of a plant loop, the 'Plant Loop Demand Calculation Scheme' needs to be set to DualSetpointDeadband.

Here's the resultant loop temperature plot from how OS is currently translating the *.osm. It can clearly be seen controlling to one setpoint. This happens to be the average of the DualSetpoint schedules. In my case this is 65°F (average of 50°F and 80°F)...

Versus correcting the field as described above (this is how the loop is expected to operate)...
