White-Rodgers 755-1 Thermostat

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.

• 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.

• 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.
