Hi

I am trying to model existing building with Constant Volume Dual Duct (CVDD)
with ECONOMIZER. Currently building uses Siemens controller. Controller
resets mixed air, hot deck and cold deck supply air temperature based on
return air. I was wondering if it is possible to reset in E-quest based on
return air temperature instead of outside air temperature. E-quest allows me
to do the reset based on outside air. Has anyone modeled reset based on
return air temperature. If yes, can you please help me or give me
suggestions. Is it possible to have some kind of source code and then import
into E-quest? Thank you for your time and help.

Regards,
