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

Cool. So, I could marry an earth tube up with Compact HVAC using EMS? Just a musing from a project I was asked about a couple of months ago.

EMS appears to be the "low level" feature that will give E+ more flexibility.

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.
