The Bryant SYSTXBBNIM01 Evolution or Carrier SYSTXCCNIM01 Infinity Network Interface Module is a product designed for HVAC and refrigeration systems. It allows for remote monitoring and control of the system through a network connection. This module is compatible with Bryant or Carrier brands and is a crucial component for efficient and effective HVAC and refrigeration management. This unit was in excellent operating condition upon removal. The only reason for removal, is because the entire HVAC system was replaced. I own an HVAC service/installation company. This was removed by myself. There is no warranty expressed or implied. And, it is the buyers responsibility to verify proper fitment or application.
