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.
Must be restricted with underfloor cooling min. flow line temp. to pre-
vent condensation.
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 curve created in menu 1.9.7.
To select another curve (slope):
NOTE
If you only have one climate system, the number of the curve is already
marked when the menu window opens.
1.
Select the climate system (if more than one) for which the curve is to
be changed.
2.
When the climate system selection has been confirmed, the curve
number is marked.
3.
Press the OK button to access the setting mode
4.
Select a new curve. The curves are numbered from 0 to 15, the greater
the number, the steeper the slope and the greater the supply temper-
ature. Curve 0 means that own curve (menu 1.9.7) is used.
5.
Press the OK button to exit the setting.
