Caution
In the event of making fine adjustments for the indoor temperature,
the heat curve must be offset up or down instead, this is done in menu
1.1 temperature .
Curve offset
An offset of the heating curve means
that the supply temperature is
changed by the same amount for all
outdoor temperatures, e.g. a curve
offset of +2 steps increases the
supply temperature by 5 °C at all
outdoor temperatures.

Flow line temperature–
maximum and minimum
values
Because the flow line temperature
cannot be calculated higher than the
set maximum value or lower than the
set minimum value the heating curve
flattens out at these temperatures.

Caution
Underfloor heating systems are normally max flow line temperature
set between 35 and 45 °C.
Check the max temperature for your floor with your installer/floor
supplier.
The figure at the end of the curve indicates the curve slope. The figure beside
the thermometer gives the curve offset. Use the control knob to set a new value.
Confirm the new setting by pressing the OK button.
Curve 0 is an own heating curve created in menu 1.9.7.
