Help! We have a system that has a space that was remodeled. The demo guys took 2 water source heat pumps out with unt controllers. The problem is that there is another space being remodeled on the other side of the building. The question is will it take the loop down if we put the controllers from there space onto the trunk in our space? Not sure we were given the correct ones. I know it's not much info but could it be a link issue? I have checked polarity and voltage on the bus in the mechanical room we are working in and from the controllers we reinstalled. It matches the readings we should be getting. We don't have good access to trace comm loop down to see where everything goes (Sheetrock ceilings):-(. Thanks for any help!
