Rheem-Ruud SP11700 Thermostat Kit

The Rheem-Ruud SP11700 is a professional-grade 120V electric water heater thermostat kit specifically engineered for single-element residential units. As the direct replacement for SP12390, this OEM component ensures seamless compatibility and restores factory-standard temperature regulation. Optimized for 120-volt circuits, the SP11700 thermostat features a single-pole (SPST) high-limit control with a 170°F safety cutoff and a manual reset button to prevent hazardous overheating conditions. The adjustable temperature range of 90°F to 150°F allows for precise thermal management, while the 5°F to 15°F differential prevents short-cycling of the heating element. This water heater thermostat kit is essential for maintaining the non-simultaneous operation required in manifold Rheem and Ruud configurations. For contractors, the SP11700 offers a reliable fix for high-limit trips or inconsistent water temperatures, ensuring the tank maintains a steady thermal profile without the risk of high-voltage arcing or thermal runaway.

• Precise Temperature Regulation: Adjustable range from 90°F to 150°F ensures consistent hot water delivery and user comfort.
• Enhanced Safety Profile: Integrated 170°F high-limit cut-off with manual reset protects the system from excessive heat buildup.
• OEM Compatibility: Specifically designed as a replacement for SP12390 and several AP-series thermostats in Rheem and Ruud tanks.
• Professional Durability: Constructed with industrial-grade metal and plastic components for long-term cycling reliability.
• Efficient Operation: Maintains tight temperature differentials to optimize energy consumption and reduce element wear.

Is the SP11700 compatible with 240V water heaters?
No, this specific kit is rated for 120V operation. For 240V dual-element residential systems, a different thermostat model is typically required for the upper and lower positions.

What does the manual reset button do?
The manual reset on the high-limit switch acts as a safety "kill switch" that trips if the water temperature exceeds 170°F, requiring a manual restart once the cause of overheating is addressed.

Why is my water heater's high-limit switch tripping frequently?
Frequent trips often indicate a grounded heating element or a faulty thermostat that has lost calibration. Swapping in a new SP11700 verifies the control side of the circuit is functioning correctly.
