NOTE: UPDATED SCHEMATICS TO ADD LDS WIRING FOR A2L COMPLIANCE. 05/14/2025.
UC600 SCHEMATICS UPDATED (REV D) TO INCLUDE LDS DETAIL ON THE 1W1 BOARD. 10/08/2025.
UPDATED ELECTRIC HEATER OPTION DIGIT 17 FROM DIGIT 21 FOR MORE RELIABLE SCHEMATIC LOOKUP RESULTS. 10/10/2025.
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 or the attached spreadsheet UCCA-MODEL NUMBER DECODER can be used to determine the correct schematic for the technician or customer. On the spreadsheet copy and paste the full model number string in cell B1; schematic finder will yield the correct number to download in cell G3 if the unit has a factory installed UC600 or 1W1 board only.
