5.4 HEAT PUMP screens - SERVICE
Carefully read the manual that accompanies the
Heat Pump before changing the values of the
following screens.
Press the icon
and scroll through the screens .
5.4.1 CLIMATE CURVES
Screens 4.6 and 4.7 define the Climate curves and the limitations
applied to the water target temperatures set in screens 4.4 and
4.5.
The Climate Curve is nothing more than the correction applied
to the target water temperature, as a function of the external
temperature.
There are the following 2 cases:
• if par. C405=0, theClimate Curve is applied exclusively toSet1
(daily screed programming).
• if par. C405=1, the Climate Curve is applied exclusively to Set2
(fan-coil).
In addition, the external reference temperature for the climate
curve:
• if C405=0, it is updated daily at 6:00.
• if C405=1, it is updated constantly.

Screen 4.6 defines the Climate curve in heating.
In addition, the maximum temperature of the hot water at the radi-
ant system is set (Par. C541)
