Description
The Trane CNT03603 SPDT Pressure Switch monitors negative air pressure conditions and actuates electrical contacts to ensure safe operation. It features a -0.07 inches water column setpoint with snap-acting switching, enabling rapid response within standard low-voltage control circuits for precise system control within HVAC systems. Installed in furnaces and air handling units, it verifies proper airflow and venting before allowing equipment operation. As part of the safety control assembly, it helps prevent improper system conditions, supports reliable sequencing, and contributes to consistent performance.
