Integrated appliance control system

An energy cut-off (ECO) system, operating independently of a thermostat means, for monitoring temperature conditions, and for discontinuing a source of energy in response to a malfunction condition, the system comprising:

• first circuit means for establishing a reference value indicative of a high-limit temperature;
• first sensing means operating independently of the thermostat means for providing an input temperature value indicative of a sensed temperature;
• first comparator means for comparing the first reference value to the input temperature value, and generating an output value indicative of the comparison;
• and
• first switch means response to the output value, wherein the first switch means discontinues the source of energy independently of the thermostat means, in response to the first reference temperature value exceeding the input temperature value.

An energy cut-off (ECO) system operating independently of a thermostat means, for monitoring temperature conditions, and for discontinuing a source of energy in response to a malfunction condition, comprising:

• sensing means operating independently of the thermostat means for generating an input voltage indicative of a sensed temperature;
• first circuit means for generating a reference voltage indicative of an open probe low-limit temperature;
• first comparator means for comparing the reference voltage to the input voltage temperature, and generating an output voltage in response to the comparison;
• and
• switch means responsive to the output voltage, wherein the switch means deactivates an associated gas valve, independent of the thermostat means, in response to the sensed temperature dropping below the open probe low-limit temperature.

An energy cut-off (ECO) system operating independently of a thermostat means, for monitoring temperature conditions, and for discontinuing a source of energy in response to a malfunction condition comprising:

• sensing means operating independently of the thermostat means for generating an input voltage indicative of a sensed temperature;
• first circuit means for establishing a reference value indicative of an open probe low-limit temperature;
• first comparator means for comparing the reference value to the input temperature value, and generating a second output value indicative of the comparison;
• and
• second switch means response to the second output value wherein the second switch means discontinues the source of energy in response to the input temperature value being less than the second reference value.
