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 sup-
plier.
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.
To select another heat curve (slope):
NOTE
If you only have one heating system, the number of the curve is already
marked when the menu window opens.
1.
Select the system (if more than one) for which the heat curve is to be
changed.
2.
When the system selection has been confirmed the heat curve number
is marked.
3.
Press the OK button to access the setting mode
4.
Select a new heating curve. The heating curves are numbered from 0
to 15, the greater the number, the steeper the slope and the greater
the supply temperature. Heating curve 0 means that own curve (menu
1.9.7) is used.
5.
Press the OK button to exit the setting.
