A fouled or oxidized sensor is a common cause of short-cycling or water heater ignition failure

Durable Construction: Features polyester-coated steel for corrosion resistance and a fused glass-to-metal seal for leak-free performance up to 650 PSI

Optimized Seal Integrity: High-quality rubber compounds provide superior resistance to thermal degradation and chemical wear in commercial hot water systems

those series typically utilize different spring models (such as the D-9502-610 or D-9502-612)

Functional Devices RIB2402B Relay How do I test aThe Functional Devices RIB2402B Relay is a heavy duty, 20 amp enclosed power relay designed specifically for the rigorous demands of HVAC control systems and industrial automation. Built with a SPDT (Single Pole Double Throw) configuration, this "Relay in a Box" (RIB) provides a reliable interface between low voltage controllers and high voltage loads. It features a multi voltage coil that accepts 24VAC DC or 208 277VAC, eliminating the need for
