Abstract: A system and method for configuring a water heater. The method includes capturing, with a mobile device a scannable feature of a rating plate and receiving, with the mobile device, an input indicative of a configuration selection. The method further includes configuring, with the mobile device, the water heater based on the configuration selection.

Abstract: A system and method for configuring a water heater. The method includes capturing, with a mobile device a scannable feature of a rating plate, establishing a network connection between the mobile device and a server, transmitting information captured from the scannable feature by the mobile device to the server over the network connection, receiving from the server to the mobile device a plurality of water heater configurations in response to the information, receiving, with the mobile device, an input indicative of a configuration selection selected from the plurality of water heater configurations, and transmitting configuration information from the mobile device to the water heater to configure the water heater based on the configuration selection.

Abstract: Methods and systems for evaluating the condition of a water tank having a powered anode protection system. The water heater includes a storage tank to hold water, a powered anode, and a control circuit. The control circuit includes a variable voltage supply, a voltage sensor, and a current sensor. The control circuit is configured to compare a measured parameter to a threshold. In some constructions, the threshold is indicative of a condition of the storage tank at which the powered anode is no longer able to protect the storage tank from corrosion. In other constructions, the threshold is predicative of a potential failure of the storage tank caused by corrosion. In some constructions, the control circuit is configured to estimate a time remaining until the predicted failure of the storage tank.

Abstract: An appliance is disclosed that includes an electrically operated load such as a gas-fired appliance having an electrically operated gas valve. A current sensing circuit is configured to sense the current provided to the load. Based upon this sensed current, it is determined whether the load is energized. Methods are also disclosed for monitoring the status of a current sensing circuit to determine the actual operating state of the load.

Abstract: A gas-fired appliance is disclosed that includes a gas valve powered by a power source. A plurality of switching units, each responsive to a condition of the appliance, are arranged in series between the gas valve and the power source. Each switching unit includes an emitter, such as an emitter of an optocoupler, that is used to monitor the opened or closed status of a switch in the switching unit. When at least one switch opens, power to the gas valve is reduced preventing the gas valve from operating. However, because this reduced power is provided to each subsequent switching unit, each optocoupler can be monitored regardless of the opened or closed status of previous switching units. As such, one or more open switches can be detected simulataneously.
