The pressure switch assembly is made of a heat-sensing diaphragm, and a plastic housing with mounting screws. The diaphragm changes resistance based on heat generated from the outdoor temperature. When the heat reaches a set point, the relay will close and power to the compressor will be connected.

A Rheem pressure switch is an electronic device that allows a water heater to operate only when needed. A pressure switch assembly is available on many Rheem water heaters. The switch assembly will shut off the power to the heater if a water pressure loss occurs, which can result in leaks or flooding.
