In terms of oil burner safety, what is the typical response of a primary control in case of a malfunction?

In oil burner safety, the primary control plays a crucial role in monitoring the operation of the burner system. If a malfunction occurs, the typical response of the primary control is to stop the unit. This is a safety measure designed to prevent potential hazards, such as fire or explosion, that could result from a malfunctioning burner.

The primary control continuously checks various parameters, such as flame presence, temperature, and pressure, and if it detects any irregularities that could indicate a malfunction, it will deactivate the burner to ensure safety. Stopping the unit helps protect the equipment and personnel from the risks associated with an uncontrolled oil burner operation.

In contrast, starting the unit or increasing pressure would be inappropriate responses, as they could exacerbate a dangerous situation. Sending an alarm signal could be a feature of some control systems, but the immediate action taken in response to a malfunction is typically to stop operation to ensure safety first.
