ARAMETER
(w/outdoor temperature sensor only installation)
The installation of an outdoor temperature sensor (see paragraph
6.7 '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 86-176
°F appliances or 77-113 °F for under-floor heating systems. The
type of appliance can be set using parameter P02.
To enter the parameters menu, follow the previously described
procedure (see paragraph 5.2 'Accessing the parameters menu'
- steps 1-5) and select parameter P12.
6. Use ' ' and ' ' buttons (D.H.W temperature setting)
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.
7. Press mode selection button '
the new adjustment operative. The parameter number (P12) will
appear on the display.
8. To exit from the parameters menu, press simultaneously '
and ' ' buttons.
