3.2 Composition of the range

3.2.1 Standard control panel- S3

Standard panel to be fitted

Panel comprising the settings, control and safety devices allowing
the boiler to operate autonomously, without regulation.

The standard panel is used to connect the boiler to the boiler room
control cabinet.
This cabinet can be fitted with control units.

3.2.2 K3 control panel

Separate panel

Panel comprising the settings, control and safety devices allowing
the boiler to operate autonomously.

Control panel K3 also allows the boiler to be used as a secondary
boiler for installations with 2 to 10 boilers in cascade, one of which is
fitted with a "DIEMATIC-m3" control panel.

Side panel



A version of the K3 control panel with lateral attachment is also
available.

3.2.3 DIEMATIC-m3 control panel

Separate panel

Top of the range electronic control panel with digital display,
comprising the settings, control and safety devices allowing the boiler
to operate autonomously.
The DIEMATIC-m3 panel is fitted as standard with a control unit
which operates according to the outside temperature.

The DIEMATIC-m3 panel also allows the boiler to be used as a
master boiler for installations with 2 to 10 boilers in cascade.

The other boilers (1 to 9) must be fitted with a "K3" control panel.

Side panel



A version of the DIEMATIC-m3 control panel with lateral
attachment is also available.

3.2.4 B3 control panel

Separate panel

Top of the range electronic control panel with digital display,
comprising the settings, control and safety devices allowing the boiler
to operate autonomously.

This panel makes it possible to give priority to DHW.

Side panel



A version of the B3 control panel with lateral attachment is also
available.
