We wanted a phone call because we were confused by the answer when your tech said "should be" so we went down to Trane and got a copy of schematic and I have attached a copy. It was not A to red and B to purple as your tech stated - it is red to B and purple to A. I should not be charged for this misinformation. thanks.
