Abstract: An appliance for conditioning air of a room comprises one or more power consuming features/functions including a temperature controlling element for one of heating and cooling air. A controller is operatively connected to the one or more power consuming features/functions. The controller is configured to receive and process a signal indicative of a utility state. The controller operates the appliance in one of a plurality of operating modes, including at least a normal operating mode and an energy savings mode in response to the received signal. The controller is configured to at least one of selectively adjust and deactivate at least one of the one or more power consuming features/functions to reduce power consumption of the appliance in the energy savings mode.

Abstract: A water heater comprises a tank, a cylinder coil section and a return-flow coil section. The cylinder coil section is in a heat transfer relationship with the tank and encircles a first portion of the tank. The return-flow coil section is in a heat transfer relationship with the tank and encircles a second portion of the tank. The cylinder coil section and the return-flow coil section are continuous over at least the first and second portions of the tank.

Abstract: A household energy management system and method for one or more appliances includes a controller for managing power consumption within a household. The controller is configured to receive and process a signal indicative of one or more energy parameters of an associated energy utility. The controller includes a user interface for receiving energy management input for at least one appliance of the one of more appliances from a user. The controller at least one of controls and operates the at least one appliance in one of a plurality of operating modes, including at least a normal operating mode and an energy savings mode, in response to the input received by the user via the user interface in conjunction with the received signal.

Abstract: A control system for an oven includes a first and a second temperature sensor, and a controller. The oven has a first cavity and a second cavity and includes, a first electrical heating element positioned within the first oven cavity, and a second electrical heating element positioned within the second oven cavity. The first temperature sensor is configured to detect a temperature within the first oven cavity, and the second temperature sensor is configured to detect a temperature within the second oven cavity. The controller is operatively coupled to the temperature sensors and the heating elements. The controller is configured to receive signals from the sensors and energize both the first and second heating elements by allowing energy to be supplied to only one of the first and second heating elements at a given time.
