Abstract: A stepper-motor gas valve control is disclosed that includes a main diaphragm in a chamber that controllably displaces a valve relative to an opening in response to changes in pressure, to adjust fuel flow through the valve. A servo-regulator diaphragm is provided to regulate flow to the main diaphragm, to thereby control the rate of fuel flow. A stepper motor is configured to move in a stepwise manner to displace the servo-regulator diaphragm, to control fluid flow to the main diaphragm. A controller mounted on the stepper-motor regulated gas valve control receives and converts an input control signal from a heating system to a reference value between 0 and 5 volts, and selects a corresponding motor step value. The control responsively moves the stepper-motor in a step wise manner to displace the servo-regulator diaphragm and thereby regulates the rate of fuel flow through the valve.

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.

Abstract: In exemplary embodiments, HVAC controls and corresponding error detection methods are disclosed. In an exemplary embodiment, an HVAC control generally includes an analog input configured to receive an analog signal, and an error indicator. The control is configured to receive a neutral signal at the analog input, measure a voltage of the neutral signal with respect to earth ground, to operate the error indicator to provide a first indicator status indicative of a bad ground state if the voltage is between a first voltage threshold and a second voltage threshold, and to operate the error indicator to provide a second indicator status of a reverse polarity state if the voltage is above the second threshold. The HVAC control may include at least four different indicator statuses. The HVAC control may include a comparator.

Abstract: Exemplary embodiments are disclosed of a climate control system that includes an igniter and a controller having an igniter relay. The controller senses a current level through the igniter and senses voltage between terminals of a second relay of the controller. In a given one of a plurality of operational phases of the system, the controller is configured to compare the sensed current level and sensed voltage to a current level and voltage associated with a specific condition of the igniter, igniter relay, or second relay in the given phase. Based on a result of the comparing, the controller is configured to distinguish between a failure of one of the relays and a failure of the igniter.
