The Landis control box starts the fan and begins the pre-purging of the combustion chamber. The air pressure switch
controls the correct operation. At the end of the pre-purging phase, the ignition transformer cuts-in followed by the
opening of the gas valves. In case of missed ignition or accidental shutdown, the ionisation probe cuts-in and set the
burner in lockout mode within the safety time.
