Description
The Trane SWT04757 Condensate Overflow Switch is a safety control component that monitors condensate levels within HVAC systems to prevent overflow from the drain pan. It is installed in air handlers, cooling equipment, and other air conditioning units where excess water could lead to equipment damage or operational interruptions. As part of the system’s securing controls, the switch detects rising condensate levels and signals the unit to interrupt operation until normal circulation is stabilized. This ensures safe system performance and assists in reducing the fluid flow limitations.
