6.4 Boiler flow temperature.
From the winter function mode ( ) it is possible to regulate
the maximum boiler flow temperature. Regulate by rotating
the selector ( ), clockwise to increase the maximum flow
temperature and anti-clockwise to decrease it.
N.B.:
during regulation, without the external temperature
probe installed, the display shows “S. RIS” and the maxi-
mum flow temperature set value. On the other hand, with
the external temperature probe installed, the display shows
“OTC” and the indication of the correlation value of the
maximum central heating flow temperature according to
the external temperature (see Fig. 23).
The boiler flow temperature during normal functioning
is however managed automatically of the CAR
V2
remote
control on the basis of the room temperature set. Therefore,
it is not certain that the boiler works at the temperature set
but functions at a lower flow temperature, but correct to
obtain the desired room temperature.
If the external temperature probe is present, the flow
temperature will be set according to that described in the
"Special functions" chapter.
6.5 Room anti-freeze function.
The anti-freeze function has maximum priority with
respect to other settings. When the room temperature
drops below 5°C (adjustable, see special functions chapter)
a central heating request is made at minimum of the power
programmed. This situation remains active until there is
a variation in room temperature of 0.6°C equal to 5.6°C
measured in the room where the CAR
V2
remote control
is positioned.
6.6 Functioning in winter mode with external
temperature probe.
If an external temperature probe is present, it is possible to
set a flow temperature correction curve depending on the
external temperature. By turning the selector switch ( )
the curve can be regulated from 0 to 9 according to the
graphics Fig. 23. Regarding this, see the activation mode in
the chapter relative to the special functions.
