Abstract: A control circuit for supplying current to actuate a gas valve in an HVAC system includes a solenoid coil adapted to selectively open and close the gas valve, input terminals coupled to receive an AC power input, and a rectifier bridge coupled between the input terminals and the solenoid coil. The rectifier bridge includes four nodes and at least four diodes. The control circuit also includes a capacitor, and a switch coupled in series with the capacitor between a ground potential and a node defined between the rectifier bridge and the solenoid coil. The switch is coupled to selectively electrically connect and disconnect the capacitor in parallel with the solenoid coil to allow the capacitor to smooth the voltage rectified by the rectifier bridge when the switch is on and to inhibit smoothing of the rectified voltage by the capacitor when the switch is off.

Abstract: A control system for a gas powered appliance includes a power source to provide electrical power to control at least one electrically actuated gas valve, a valve control system to selectively couple electrical power from the power source to the electrically actuated gas valve, and a controller. The valve control system includes a first switch and a second switch. The first switch and the second switch are electrically connected in series between the power source and the electrically actuated gas valve. The controller is operatively connected to the first switch and the second switch and configured to control the first switch and the second switch to selectively couple power from the power source to the electrically actuated gas valve.

Abstract: A modulating gas valve assembly includes a modulating gas valve to variably control a flow of gas through the gas valve assembly and a control circuit. The control circuit includes a valve memory storing a calibration table for the modulating gas valve, and a controller communicatively coupled to the peripheral component. The calibration table includes a plurality of control settings for the modulating gas valve, each control setting being associated with a different gas flow rate. The controller is programmed to receive a command to open the gas valve, and to control the gas valve to a target control setting in the calibration table adjusted in accordance with a valve offset.

Abstract: A control system for controlling a gas powered water heater includes a thermoelectric generator to provide electrical power at a first voltage, a valve control system to selectively hold a main gas valve in an open position, a valve pick system to selectively pick the main gas valve from a closed position to the open position using the electrical power at the first voltage, and a power converter. The controller is electrically powered by a boosted electrical power at the second voltage from the power converter. The controller is communicatively coupled to the valve control system, the valve pick system, and the safety system. The controller is configured to control operation of the main burner and the main gas valve using the valve control system, the valve pick system, and the safety system to provide water heated to substantially a setpoint temperature.

Abstract: A processor for a controller of a water heater is configured to receive water heater control parameters and an output from a sensor indicating a measured temperature of water in the water heater. The processor is also configured to determine whether to enter an anti-stacking control mode or to enter a demand anticipation control mode. In the anti-stacking control mode the processor is configured to initiate a call for heat when the measured temperature reaches a trigger temperature, calculate a burner on delay value and set a second timer with the calculated value, and calculate a reduced activation time. In the demand anticipation control mode the processor is configured to increase the variable offset based on a frequency of the demand anticipation control mode being activated, initiate a call for heat, and control, based on the reduced activation time or the increased offset value, the burner.

Abstract: A safety system for use with a thermoelectric generator is described. The safety system includes a safety switch operatively connected to the thermoelectric generator output. The safety switch has a first state in which the thermoelectric generator can provide a first voltage to a load, and a second state in which the thermoelectric generator cannot output the first voltage to the load and in which the thermoelectric generator can output a second voltage to the load. The second voltage is a non-zero voltage having a magnitude less than the first voltage.

Abstract: A gas valve assembly includes a gas valve and a control circuit. The gas valve is configured for variably controlling a flow of gas through the gas valve assembly. The control circuit includes a controller programmed to determine a first setting for the gas valve in response to a received commanded flow, adjust the first setting to a second setting based on a measured temperature when the measured temperature is one that may induce changes to the flow of gas through the gas valve assembly, and control the gas valve based on the second setting.
