Abstract
A gas valve () control system () uses a control signal () to enable a valve () and a validation signal () to validate the control signal (). The system () includes a valve () connected to a burner (). A receiver () is electrically connected to the valve () and provides the valve () with the control signal (). A controller () has a control transmitter () in wireless communication with the receiver () to transmit the control signal () to the receiver () at a speed of light. The controller () further includes a validation transmitter () to transmit a validation signal () to the receiver () at a speed of sound. The valve () is enabled by the control signal () if a time delay between the receiver () receiving the control signal () and the validation signal () is shorter than a maximum delay period. The control signal () is discarded if the time delay is longer than the maximum delay period.
