Hi all,

I need help please

I am very new to IES and I need to activate a night purge to try and reduce some space temps but I have no clue where or how to find this. I am looking for some advice please if anybody can help?

This can be a bit complex so I can't go through everything here in a short post, but what you will need to do it define some openings in MacroFlo which you control to open at specific times at night you can either use windows or doors to modulate). You would just define a schedule (intelligent using formulas, or just based on hard entered times) to do the control. Just be sure your HVAC system turns off during this time! To make MacroFlo run, be sure to select the box in the apache sim menu for it.
