Re: [EnergyPlus_Support] How to change the heating and cooling supply air temperature set point
This is a compact file. When you run this file you will get and expanded
file (*.expidf). Save this file as *.idf and edit it. In the IDFEditor,
click the View menu and select Single File, then pick EXPIDF file or use
a text editor and open it yourself. You will notice that the
HVACTemplate objects are now commented out and the E+ objects you need
are inserted for you. You will find this object. Then change the
settings and save. Then RUN THIS FILE, not the
HVACTemplate-5ZonePurchAir file.
