PARAMETER P15 – LEGIONELLA PREVENTION FUNCTION
(For storage boilers only)
To enter the parameters menu, follow the previously described
procedure (see paragraph 5.2 ‘Accessing the parameters menu’ -
steps 1-4).
5. Use
and buttons (D.H.W temperature setting) to modify
the value of the parameter:
00 = Off
01 = On
6. Press mode selection button
to confirm and to render the new
parameter operative.
7. To exit from the parameters menu, press simultaneously
and
buttons.
PARAMETER P16 – SETS THE CLIMATIC COMPENSATION CURVE
(w/outdoor temperature sensor only installation)
The installation of an outdoor temperature sensor (see paragraph 6.6
‘Electrical connections’) allows to automatically modify the flow
temperature in accordance to the outdoor temperature. The factor governing
the correction is the Kd thermoregulation value, indicating the flow
temperature range selected (fig.1).
The maximum flow temperature Tm and the minimum outdoor temperature
Te taking into consideration the house insulation degree determine the
selection of the compensation curve.
The values of the flow temperature Tm, refer to standard 30-80 °C
appliances or 25-45 °C for under-floor heating systems. The type of
appliance can be set using parameter P03.
To enter the parameters menu, follow the previously described procedure
(see paragraph 5.2 ‘Accessing the parameters menu’ - steps 1-4) and
select parameter P16.
5. Use
and buttons (D.H.W temperature setting) to modify
the value of the parameter within the range of setting from 00 to 30.
The value corresponds to the graph curves in figure n.1.
6. Press mode selection button
to confirm and to render the new
parameter operative.
7. To exit from the parameters menu, press simultaneously
and
buttons.
