[Equest-users] Question: Two pipe system with Chiller or Boiler and F.C.U

[Brian Fountain]

This one would likely be easier to troubleshoot if you could provide the .inp file.

How did you set up the controls on the 2-pipe loop to switch between heating and cooling?  Was there an explicit schedule or is it snapping on outdoor temperature?  If the latter there may be hours in the winter above your snap temperature flipping the loop to cooling mode.  An explicit schedule will preclude that.  The 2-pipe loop is either-or so what you describe is unusual.
