The Resideo L4064B2228/B 5″ Fan and Limit Controller Insert is a required control component used in the HVAC systems to regulate the operation of the blower and temperature limits in furnaces. The working concept of this system component is that the heat in the plenum is detected, and the fan and burner are switched to cycle at predefined values. It is fitted in commercial and residential forced-air heating parts and has a vital role in the system concept, regulating the time of airflow, ensuring safe temperature levels, and minimizing the excessive heating in the normal operation of a furnace.
