1. Trane Rover service tool uses the unit type to help determine and download the proper default analog input configuration.
2. Analog input 3 (AI 3) configured as generic temperature input does not affect unit operation. When configured, the Tracer
TM
ZN524 unit con-
troller communicates the generic temperature value to Rover or Tracer Summit and displays it as generic temperature.
