Description
The Trane CNT4355 Fan & Limit Control is used to regulate blower fan operation and monitor furnace temperature in heating equipment. It is placed inside the furnace control compartment of the unit in HVAC systems. It responds to temperature changes within the heat exchanger to start or stop the blower at predetermined settings while interrupting burner operation. It combines fan control and temperature limit operations within a single control assembly to manage blower cycling and protect the system from excessive heat conditions.
