Curve coefficient
The slopes of the heating /cooling
curves indicate how many degrees
the supply temperature is to be in-
creased/reduced when the outdoor
temperature drops/increases. A
steeper slope means a higher supply
temperature for heating or a lower
supply temperature for cooling at
a certain outdoor temperature.
The optimum slope depends on the climate conditions in your location, if
the house has radiators or under floor heating and how well insulated the
house is.
The curve is set when the heating installation is installed, but may need
adjusting later. Normally, the curve will not need further adjustment.
Caution
In the event of making fine adjustments of the indoor temperature, the
curve must be offset up or down instead, this is done in menu 1.1
temperature .
Curve offset
An offset of the curve means that
the supply temperature changes as
much for all the outdoor temperat-
ures, e.g. that a curve offset of +2
steps increases the supply temperat-
ure by 5 C at all outdoor temperat-
ures.
