摘要： A burner control system for improving burner performance and efficiency may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.

摘要： A water heater having a monitoring mechanism, an appliance burner configured to heat water in a tank of a water heater, a water temperature sensor configured to detect a water temperature in the tank, a pilot device configured to ignite the appliance burner, and a thermopile having a tip and a base, and having an output voltage that represents a temperature difference between the tip and the base. The tip of the thermopile may be heated by the pilot device. The base of the thermopile may receive heat from the appliance burner when the appliance burner is turned on, and thus the voltage output of the thermopile may decrease. If the voltage output does not decrease and the water temperature exceeds a thermal cutout limit, then a warning about the water heater may be issued by the monitoring mechanism.

摘要： An illustrative HVAC controller may include a communication module for wirelessly communicating with a network and wiring terminals for receiving a wired connection to a remote temperature sensor that is situated remote from the HVAC controller and in a living space of the building. A controller may be operably coupled to the communication module and the wiring terminals and may be configured to implement a thermostat control algorithm to generate one or more control signals, wherein the one or more control signals are provided by a wired connection to the HVAC system to control one or more HVAC components of the HVAC system. The thermostat control algorithm may be configured to compare a sensed temperature received from the remote temperature sensor via the wiring terminals and a temperature setpoint received from the server via the network.
