System involved with but not limited to an apparatus including a temperature control system capable of quickly heating a grill to a precise and consistent temperature using a plurality of gas burners and associated electronic control method thereof. In an exemplary non-limiting application, the system uses a solenoid valve to control flow to a plurality of motorized modulating valves, which in turn modulate gas flow to a gas burner. The apparatus and method of use thereof is capable of producing precise cooking temperatures by adjusting the volume of gas flow to the burners via motorized modulating valves, allowing for more precise and consistent cooking temperatures than systems utilizing valves featuring only a limited number of positions, such as open or closed, or high flow or low flow.
