Function
- Siemens LME22 control and safety unit
The Siemens 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 UV cell cuts-in and set the burner in lockout mode within the safety time.
