Trane CNT3520 Pressure Switch monitoring the heat exchanger andThe Trane CNT3520 is a critical OEM HVAC pressure switch engineered for precise negative pressure detection in residential and commercial air handlers and furnaces. As a single pole double throw (SPDT) switch, this component provides versatile electrical control, allowing for normally open or normally closed circuit configurations depending on the sequence of operation. Calibrated to a fixed setpoint of 0. 15" WC (water column), the CNT3520 serves as
