Boiler Flow Temperature; Room Anti-Freeze Function; Functioning In Winter Mode With External Temperature Probe - Immergas CARV2 Instructions For Use Manual

6.4 Boiler flow temperature.
From the winter function mode ( ) it is possible to regulate
the boiler flow temperature. Regulate by rotating the
selector ( ). Clockwise increases the flow temperature,
anti-clockwise decreases it.
N.B.: an excessively low boiler flow temperature adjustment
(below 60°C for traditional systems) may not allow to reach
the desired room temperature.
The boiler flow temperature during normal functioning
is however managed automatically of the CAR
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
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
remote

the chapter relative to the special functions.
