Description
The Trane CNT3602 Pressure Switch is an essential component to monitor air temperature levels within HVAC systems. It operates by detecting differential pressure and activating or deactivating system operation based on a preset threshold of 0.45″ of water column, ensuring proper airflow conditions are met. Commonly used in furnaces and air handling units, it is installed near the inducer or venting system. As part of the safety circuit, it supports verifying correct draft conditions before ignition, preventing unsafe operation and supporting system performance.
