Nibe S1256PC Installer Manual page 39

Here, you set the highest supply temperature for the climate
system. This means that S1256PC never calculates a tem-
perature higher than the one set here.
If there is more than one climate system the setting can be
made separately for each system. Climate systems 2 – 8
cannot be set to a higher max supply temperature than cli-
mate system 1.
Caution
With underfloor heating systems, "Maximum supply
temperature for heating" should normally be set
between 35 and 45°C.
MENU 1.30.7 - OWN CURVE
Own curve, heat
Supply temp
Setting range: 5 – 80 °C

You can create your own heating curve here, if there are
special requirements, by setting the desired supply temper-
atures for different outdoor temperatures.
Own curve, cooling
Supply temp
Setting range: 7 – 40 °C
Caution
Curve 0 must be selected for own curve to apply.
You can create your own cooling curve here, if there are

MENU 1.30.8 - POINT OFFSET
Outdoor temp. point
Setting range: -40 – 30 °C
Change in curve
Setting range: -10 – 10 °C
Select a change in the heating curve at a certain outdoor
temperature here. One step is usually enough to change the
room temperature by one degree, but in some cases several
steps may be required.
The heating curve is affected at ± 5°C from set outdoor
temp. point.
It is important that the correct heating curve is selected so
that the room temperature is experienced as even.

TIP
If it feels cold in the house at e.g. -2°C, "outdoor
temp. point" is set to "-2" and "change in curve" is
increased until the desired room temperature is
maintained.
Caution
Wait 24 hours before making a new setting, so that
the room temperature has time to stabilise.
