The Swimables SW-41-024 stack flue sensor is a critical safety device for Pentair MasterTemp and Max-E-Therm pool and spa heaters. It continuously monitors exhaust gas temperature and triggers an automatic heater shutdown when flue gases reach 480° F (249° C), preventing dangerous overheating conditions. Engineered to cap flue gas output at a maximum of 500 degrees Fahrenheit, the sensor provides an essential thermal safeguard for your heating system. It operates reliably across a broad ambient temperature range of -20°C to 105°C, making it suitable for installations in virtually any climate. Beyond its protective function, this sensor also addresses common diagnostic trouble codes including E-02, E-05, and E-06, helping restore normal heater operation when these faults appear on your control panel.
