Almost all PVI water heaters regardless of the energy source employ two levels of operating control. The primary operator (A) will sense temperature at the bottom of the tank and is the main control that calls for heat. The second operator (B) acts as a "first high limit" with a setting 10 degrees above the operating control and with a probe located in the upper portion of the storage tank. This second operator will disable a call for heat from the main operator if the temperature at the top of the tank is already above its set point because of tank stratification. This safety control prevents potential over-heating of the water. These controls are in addition to the automatic or manual reset high limit required by UL, ANSI, and CSD-1 standards that shuts of heater operation only if water temperature exceeds 190 degrees.

While available on some competitors gas fired heaters, this dual operator arrangement is rare among manufacturers of water heaters using steam or boiler water to heat domestic water.
