Trane CNT0674 v 318820-201 This transmitter requires aThe Trane CNT0674 is an industrial grade 170 210F AUTO Limit Switch designed for high performance temperature regulation in forced air systems. As a SPST N C (Single Pole Single Throw, Normally Closed) safety control, this component is critical for preventing heat exchanger overheating. The switch is calibrated to open at 210F, effectively interrupting the burner or heating circuit when thermal limits are exceeded, and automatically resets when
