Regulation and control system
The control and regulation system located on board machine
allows the following adjustments / controls:
fixed point;
•
at a sliding temperature (climatic);
•
production of domestic hot water.
•
Fixed Point Control
With fixed point control, the flow temperature remains constant
until the user makes a modification. With both a single system
and an in cascade, up to 3 room thermostats can be installed
(accessories not supplied by Rinnai), for three different
zones, suitable for command the ignition or shutdown of the
generator, according to environmental demands. In this case,
the three different zones will be able to request heat through
a digital signal sent by the thermostat (ON / OFF) to the PCB
(LMS 14). The connections of the room chronothermostat
should be carried out from the input terminals H4, H5 and H6
of LMS 14.
Sliding Temperature Adjustment
Through the installation of the external climatic probe, the
boiler autonomously modifies the flow temperature and adapts
its operation to climatic conditions external, while maintaining
the internal thermal comfort and reducing waste. The climatic
curve of the generator has the function of automatically
modifying the flow temperature to the heating system at
vary in external conditions (in particular when the external
temperature). To establish the correct climatic curve of a
system, it is necessary to know the temperatures of design of
the system itself (flow temperature) and the external design
temperature. By relating these data on the diagram of climatic
curves, the curve is identified closest to the needs of the plant
in question.

Domestic Hot Water Production
By connecting a temperature probe to the boiler and the
installation of a pump can be managed the temperature of the
domestic hot water directly from the electronic board on the
machine.
