Description
The Copeland 755-1 is a water heater thermostat designed to open on a high temperature condition, with an operating range of 90°F to 150°F, providing primary temperature control and high-limit safety switching for residential and light commercial water heating equipment. Water heater thermostats of this type sense tank or element surface temperature and interrupt the heating circuit when the set point is reached, cycling the heating element or burner on and off to maintain the desired water temperature within the operating range. The open-on-high action serves a dual function as both a normal operating control and an overheat safety device, cutting power to the heating source when water temperature climbs beyond the acceptable threshold to prevent scalding, pressure buildup, and equipment damage. The 90°F to 150°F range covers the standard residential hot water delivery temperatures recommended for domestic use and accommodates the factory and field set point requirements of most residential electric and gas water heater platforms. As an Emerson OEM-quality replacement thermostat, the 755-1 is a direct-fit service component for water heater maintenance and repair applications where the original thermostat has failed or requires replacement due to set point drift or contact wear.
