Systems and methods for controlling a variable gas valve

Abstract

A gas-powered heating system includes a burner, a modulating gas valve connected between a gas source and the burner to variably control a flow of gas from the gas source to the burner, and a peripheral component including a control circuit having a memory storing a calibration table for the modulating gas valve, and a processor. 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 control circuit is programmed by instructions stored in the memory and executable by the processor to receive a valve offset, determine to open the modulating gas valve, and control the gas valve to a target control setting in the calibration table adjusted in accordance with the valve offset.
