(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 selection of the compensation curve is determined by the
maximum flow temperature
Tm
and the minimum outdoor
temperature Te taking into consideration the house insulation
degree.
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
