LEC1...
Control unit for double- or multiflame supervision of oil, gas or forced draft oil /
gas burners of any fuel throughput, suited for continuous or intermittent opera-
tion.
The LEC1... and this Data Sheet are intended for use by OEMs which integrate the

Use
The LEC1... is designed for the fully automatic startup and supervision of forced draft
oil or gas burners where flame supervision should or must be carried out by separate
flame safeguards, e.g. with:
• Double supervision of the main flame or pilot and main flame by 2 identical or dif-
ferent detectors
• Supervision of forced draft oil / gas burners with different types of detectors, de-
pending on the selected operating mode
• Multiflame supervision, that is, central and simultaneous control of the startup and
supervision sequence of several burners the flames of which must be individually
supervised by 1 or 2 flame safeguards each
