RE: [EnergyPlus_Support] Re: Use hourly data from file as OA supply temperature.

The EMS feature includes “actuators” for nodes registered as outdoor air nodes.  The level of ease probably varies from person to person but it is fairly simple to setup a sensor based on a schedule and then set that value to an “Outdoor Air System Node” actuator.  You should set values for both the Drybulb and Wetbulb for a full description of the inlet air conditions.

Schedule:File is quite a useful object. However, can you easily overwrite the conditions of the outside air node that compact hvac references? If so, how?
