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 temper-
ature .
Curve offset
An offset of the heating 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.

Flow line temperature– maxim-
um 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.
