[Equest-users] VRV Systems

Rob,
If you are using 3.64, I've had the same problem. Not sure if it's a bug, but I've sent example files and problems to Jeff Hirsch without any answer. Maybe we will hear something soon.

Subject: [Equest-users] VRV Systems

I am having trouble figuring out how to model successfully the VRV systems with an air cooled condenser.  I am using a Make up Air unit ( SYSTEM = PVAV) in a dummy zone and then attaching my evap unit system to it via OA-FROM-SYSTEM.  my individual evap units are currently PVVVT, with air cooled condensing units set to variable speed.
I followed the instructions in that powerpoint presentation that was passed along the users group and have not been able to get it to work.
my unmet hours in heating are very large.  is this the approach that anyone has used before and made it work?  does anyone have any tips/tricks to make this thing work?

By the way, i sent this message once with the powerpoint attached, and it was too large and i needed to wait for the moderator, so i sent this to get faster answers.

thanks,
