1.Trane Rover service tool uses the unit type to 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™ ZN .520 Unit

Controller communicates the generic temperature value to Rover or Tracer Summit and displays it as generic temperature.
