It monitors and regulates water temperature at the top of the tank, cycling the upper heating element on and off to maintain the setpoint. This is a 3-point thermostat, meaning it connects via three electrical terminals. Licensed plumbers and HVAC technicians install this part during routine thermostat replacement or when troubleshooting inconsistent hot water output on residential electric water heater systems.\u003c\/p\u003e\u003cp\u003eThis upper thermostat is intended for use in residential electric water heater applications where the tank relies on a two-element configuration. The upper thermostat takes priority during the heating cycle, bringing the top portion of the tank to temperature before the lower element engages. It is a direct replacement part suited for standard electric tank-style water heaters using a 3-point upper thermostat configuration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-point terminal connection for upper element control\u003c\/li\u003e\n\u003cli\u003eUpper position thermostat for priority heating in two-element systems\u003c\/li\u003e\n\u003cli\u003eDirect OEM-style replacement design\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for standard water heater thermostat pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement upper thermostat for residential electric tank water heaters requiring a 3-point upper thermostat.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified technician.
