Setting the boiler water temperature

in heating mode with the maximum boiler water
temperature rotary selector [1] according to Tab. 3.
NOTICE: System damage in underfloor
heating systems through overheating the
pipework!
B For underfloor heating systems, never set
the boiler water temperature higher than
40 °C.
To save energy, set the maximum boiler water
temperature low enough that it is still
sufficiently warm inside the building.
The required room temperature cannot be
achieved if this temperature is set too low.
For further details regarding energy saving,
