Can anyone point me to a website for current Trane rooftop units, and possibly wiring schematics. Info for the onboard ddc would be excellent. I have a customer 10 hrs away with a new unit giving trouble even with the ddc manually jumpered out. the local techs are giving up for tonight, and I would like to help them out in the morning. I am not a trane dealer, only controls, so I don't see a conflict.
PS it is -20 degrees C where the unit is and the inside of the building is cold
