I think we are both right here. Just pulled a new t stat out of the truck. The y and g are common when the t stat is in cool position only. When the t stat is in off or heat those two points are isolated. So the hrv will kick the Ac and furnace fan on if in cool. However op said the problem exists when the t stat is off or heat as well.
