Trane RTU YCD075
In all my years in the HVAC world i never thought I would run into a simple low vol. wiring problem but I am baffled. I have a Trane YCD075 roof top unit and am tryin to wire a trane non programmable zone sensor/ tsat to it but do not understand how to wire it to the teminal strip. I tried wiring it to the same terminals the programmable stat was wired to with no prevail. Also the wiring diagram on the door is destroyed... thanks a whole lot trane for putting the schematic on a door that recieves weather damage! Any help on this situation would be great.... THANKS!!!

Maybe Jay will find this and correct me if I'm wrong.....[Avatar photo from a Florida training accident. Everyone walked away.]
