Description
The Field Controls 46089800 Inducer Proving Switch DIP-1 is a safety part that monitors airflow from the draft in HVAC systems. It operates by detecting sufficient air pressure within the housing, closing its internal contacts when proper flow is confirmed, and signaling the control board to allow ignition. This switch is installed in furnaces and boilers to ensure they are operating before combustion begins, preventing unsafe operation. By verifying airflow, it protects the system from backdrafts, maintains efficient combustion, supports heating performance, and reduces the risk of damage or operational interruptions, ensuring safety.
