Rheem SP11698 – Upper Electric Thermostat for Non-Simultaneous Electric Water Heaters

The Rheem SP11698 is a replacement upper electric thermostat designed for residential electric water heaters utilizing a non-simultaneous element configuration. It provides temperature regulation and safety shutoff functionality by monitoring tank water temperature and controlling the heating element accordingly.

Product Overview

This thermostat features a dual-function design that includes both temperature control and a high-limit safety cutout. It is equipped with a manual reset mechanism and is factory-calibrated for reliable performance in electric water heating systems. The SP11698 is designed for compatibility with select Rheem electric water heater models and can be installed using standard mounting practices.
