Burner controls for the supervision of 1- or 2-stage gas or gas burners of small to medium capacity, with or without fan in intermittent operation.
The LME39 and this Data Sheet are intended for use by OEMs which integrate the burner controls in their products.

LME39 are used for the startup and supervision of 1- or 2-stage gas or gas burners in intermittent operation. The flame is supervised with an ionization probe or a QRA UV flame detector with an AGQ3.xA27 ancillary unit for forced draft gas burners.

• Type-tested and approved in accordance with DIN EN 298
   
• Undervoltage detection
• Air pressure supervision with function check of the air pressure switch during startup and operation (depending on the respective parameterization)
• Electrical remote reset facility
• Multicolor indication of fault status and operational status messages
• Limitation of restarts
• Accurate program sequences thanks to digital signal handling
• Controlled intermittent operation after a maximum 24 hours of continuous operation
