Rheem SP11700 Electric Thermostat – Single-Pole High Limit Control for Electric Water Heaters

The Rheem® SP11700 is a 120V single-pole electric thermostat with high-limit protection, designed for use in residential electric water heaters. This thermostat regulates temperature through a bi-metal disc and includes a built-in safety cutoff to prevent overheating. It supports non-simultaneous operation by controlling a single heating element at a time.

Application and Compatibility

Suitable for residential electric water heaters utilizing one or two elements, the SP11700 is engineered to manage top or bottom element operation in systems that do not require both elements to run simultaneously. It is commonly used as a direct replacement for factory-installed thermostats in standard electric tank-style units.

Performance Features

• ✅ High-Limit Safety Function – Integrated manual reset safety feature protects against excessive water temperatures.
• ✅ Bi-Metal Temperature Sensing – Provides fast-acting, reliable switching based on tank temperature.
• ✅ Standard Footprint – Compatible with typical electric water heater thermostat mounting brackets.
• ✅ Non-Simultaneous Design – Controls a single element per cycle to reduce system load and energy use.
