Abstract
A residential energy controller includes a first bi-metal element having a free end and a stationary end. A second bi-metal element has a first end connected to the free end of the first bi-metal element. The second bi-metal element is included in a thermostat that controls an air conditioning apparatus for cooling the residence. A sensing device senses current delivered to the residence and produces a corresponding sense current. The first bi-metal element is electrically resistive. The sense current is forced through the resistive material of the first bi-metal element, causing it to be heated to a temperature that is related to the amount of power being delivered to the residence, thereby causing the free end of the first bi-metal element to rotate and causing the entire second bi-metal element to rotate. This causes the turn-on temperature of the thermostat to be increased by an amount related to the total power being delivered to the residence. A switching device mechanically connected to the first bi-metal element causes a hot water heater of the residence to be turned off as a result of rotation of the first bi-metal element caused when the air conditioning apparatus is turned on.
