Emerson Climate-White Rodgers 755-1 Electric Water Heater Thermostat Open On Rise 90°F/150°F

The Emerson Climate-White Rodgers 755-1 Electric Water Heater Thermostat is a single-pole and open-on-rise electric thermostat with an operating range of 90F to 150F. When stored water reaches the upper threshold the component breaks the electrical circuit, cycling the heating element off to prevent over heating. Found in electric water heaters across HVAC system settings, it mounts flush against the tank wall to read the stored water temperature directly. Within the heating system, this thermostat manages the element's on/off cycle, balancing hot water availability with protection against thermal stress.
