Problem:
The schematics are missing from the UCCA Performance Climate Changer Air Handler. I cannot find or regenerate the schematics using ComfortSite or Trane Select Assist.
Solution:
If you have the model number from the unit or know the fan configuration and/or controller option selection, you can use the decoder ring below to determine the correct schematic for the technician or customer.
