  • Electronic temperature limiting control
    Patent number: 12392525
    Abstract: An energy cutoff apparatus for a water heating system includes a safety cutoff circuit and a presence detection circuit. The safety cutoff circuit receives a temperature signal from a temperature sensor. The temperature signal is indicative of whether a temperature of water in the water heating system within a permissible temperature range. The safety cutoff circuit disables a safe operation current branch when the temperature signal indicates the water temperature is outside the permissible water temperature range. The presence detection circuit detects a presence of the temperature sensor and disables a presence detection current branch if the temperature sensor is absent. Switches can power heating elements of the water heating system responsive to the safe operation current branch being enabled and the temperature sensor being present and can disable the heat elements responsive to the safe operation current branch being disabled or the temperature sensor being absent.
