Nti 81896 Flow Switch FS-380 for TI150C TI200C M100 T150C T200C

Product Description

The NTI 81896 is a replacement flow switch, model FS-380, designed for use with NTI boiler systems including the M100, M100V, T150C, T200C, TI150C, and TI200C models. Flow switches are critical safety and control components in hydronic heating systems. They detect whether water is moving through the system before allowing the burner to fire. This protects the heat exchanger from dry firing, overheating, and premature failure. Without a functioning flow switch, a boiler cannot confirm that circulation is active, which can lead to serious equipment damage and unsafe operating conditions. HVAC technicians and hydronic heating professionals rely on OEM-matched replacement parts like the NTI 81896 to restore proper boiler operation quickly and with confidence. The FS-380 flow switch fits directly into the NTI boiler lineup it was engineered for, eliminating compatibility guesswork during a service call. NTI boilers are known for their high-efficiency condensing design, commonly installed in residential and light commercial settings. When a flow switch fails, symptoms can include boiler lockout, error codes related to circulation faults, or the system failing to ignite. Replacing the flow switch with the correct OEM part is the standard repair approach. The NTI 81896 restores the boiler control circuit to factory specification, ensuring the system reads water flow accurately and operates safely. This part is a straightforward drop-in replacement for technicians already familiar with NTI equipment. Keeping this part on hand reduces downtime during heating season service calls.
