AUTOMATIC CONTROL SYSTEMS FOR
OIL BURNERS APPLICATION
The electro-mechanical controllers of this series are
designed to control oil burners in non-permanent
applications.
These controllers are suitable for :
− monoblock burners
− power washers
− hot air generators
− steam boilers
− furnaces
Due to the models technical and constructive features and
to their variety they can be used also for the automation of
cookers, and of plants employing oil burners generally,
whether in domestic or industrial applications. These
controllers replace integrally the 03 electro-mechanical
series
FEATURES
Table 1 shows the main features of this series.
Other important features are:
− two independent safety contacts for valve driving
− electrical service life at max. declared load > 250.000
operations;
− Easy installation and connection.

CONNECTION
TECHNICAL DATA The connection bases type B and N can be provided to
connect the external components to the controller (see Fig.
Power supply : 220V 50/60Hz 2). Both bases are provided with screw terminals which
Upon request: 110V 50/60Hz allow a safe and easy connection. It’s advisable to use M4
24V dc and ac 50/60Hz screw for fastening purpose.
