If the TD7 on a Symbio 800 controlled Intellipak is not communicating or you have a Unit without a local TD7 (RAUK units with Digit 22 = 0 in the model number), you can connect your laptop to the USB port on the Symbio controller and use the link below to have the TD7 information on your laptop. It will look and function just like the TD7 on the unit. You can view information and change settings as if you were changing them on the unit mounted TD7.
