The White-Rodgers 755-1 is a professional-grade surface mount water heater thermostat designed to handle the high electrical capacity requirements of residential and light commercial electric water heaters. This SPST water heater control features open-on-rise switching logic, effectively cutting power to the heating element when the preset temperature is achieved. Operating with a variable range of 90°F to 150°F (32°C to 66°C), it serves as the direct replacement for the legacy White-Rodgers 755-11, ensuring seamless mechanical compatibility. Built with snap-action contacts for long-term cycling reliability, the 755-1 is rated for up to 30 Amps at 240 VAC resistive loads. It is a critical component for technicians requiring a field-proven 90/150F thermostat that integrates into standard upper or lower element configurations when paired with appropriate high-limit safety controls. Key Benefits Direct OEM Replacement: Engineered to replace 755-11 models without mounting modifications. High Amperage Rating: Rated for 30 Amps at 120-250 VAC, making it suitable for high-wattage resistive heating elements. Snap-Action Switching: Provides fast, positive circuit breaking to prevent contact pitting and extend component life. Universal Surface Mount: Standard flat-back design fits securely against the water heater tank surface for accurate temperature sensing. Common Questions Is the White-Rodgers 755-1 a direct replacement for the 755-11? Yes, the 755-1 is the manufacturer-specified successor and provides identical electrical and mounting specifications. What does "Open-Hi" mean for this model? This indicates an "Open on Rise" operation, where the switch disconnects the circuit once the high temperature setpoint is reached. Can this thermostat be used in dual-element systems? Yes, the SPST configuration is typically used to control a single element or as part of a multi-control system in standard electric water heaters.
