Connecting temperature limiter
In order to prevent the boiler from
overheating
due
to
the
regulator
malfunction, an STB safety temperature
limiter, or any other appropriate for the
given boiler and heating system, should be
fitted.
The STB limiter can be connected to
terminals 1-2, as specified in Drawing 31.
When the limiter is activated, the airflow and
fuel feeder motor are disconnected.
The temperature limiter must
have nominal operating voltage of
at least ~230V, and it should have
the applicable permits.
If the limiter is not connected to terminals 1-
2, a bridge should be made. The bridge
should be made of wire the section of which
is at least 0,75 mm
2
, with insulation thick
enough to comply with the boiler safety
requirements.
The current regulations demand
that a safety temperature limiter
is used.

It is possible to connect an additional control
panel, situated in the living quarters, e.g. in
a kitchen. The additional panel is not
supplied as standard. When making the
electric connection, observe the following
requirement:
only
one
panel
can
be
connected to one executive module of the
regulator. If an additional mixer module is
not connected to the regulator, it is
necessary to apply an extra power adaptor :
