Carrier SYSTXBB4ZC01 Evolution Damper Control

The Carrier SYSTXBB4ZC01 Evolution Damper Control is an electronic module manufactured for application in Carrier Evolution HVAC systems. It is used together with the system’s thermostat and dampers not included to offer zoned comfort in your home. Old school air conditioning systems control a single zone of the house, meaning some parts of the house may be over-cooled or over-heated. They do this by electronically controlling dampers that are placed within the duct work. These dampers operate to control the flow of air to the particular zones to allow each zone get the right amount of heat.
