This sensor is commonly utilized in Infinity and Evolution series heat pumps and condensers where precise feedback is required for two-stage and variable-speed operation

Built to withstand demanding HVACR environments

as the relay will not detect an overload condition relative to that motor’s specific thermal limit

Excessive vent lengths beyond the manufacturer’s specification can also cause nuisance tripping

removing the need for ongoing maintenance cycles and protecting the internal ball bearings from premature wear

Trane SWT3926 Pressure Switch 328140-751 This sensor is commonly utilizedThe Trane SWT3926 Pressure Switch is an essential OEM safety component designed for precise condensate management in American Standard and Trane air handlers and furnaces. As a 24V furnace pressure switch, it monitors for restricted drainage or secondary heat exchanger blockages, preventing potential water damage and system failure. This SPST condensate switch is a direct drop in replacement for part number D345669P01, ensuring high reliability
