- The factory does not support this modification. Part ID, how to, instructions, etc.
- Every part in the control box changes with the exception of the ECM board (VelociTach™ Motor Control Board) .i.e. blue board with display.
- All of the harnesses have different connectors because they are wired into the UC400 instead of the CSTI board.
- Also, with UC400-B or Symbio 400, the motor cannot be controlled independently because the fan control is through the IMC link.
You could contact field modifications at the link below to see if they would entertain this change. Part ID only.
