Description
The Trane SWT3832 Switch measures pressure differentials across the air handling system. It sends an electrical signal to the control board to confirm adequacy of airflow before allowing the activation of the burner or heating sequence in HVAC systems. A diaphragm element responds to pressure changes by opening or closing the internal circuit and ensuring the system operates only when the airflow conditions meet the required parameters. It connects directly to the pressure port without requiring additional fittings or wiring alterations. Accurately, this pressure detection prevents equipment from the running under restricted airflow, reduces mechanical stress, and ensures the safe sequencing at every stage of operations.
