contains water (see 4.3.2).

Fig. 4.13 Setting the maximum radiator temperature control
Set the maximum radiator temperature control to the
desired setting using the control knob (1).
We recommend the following settings:
– Left setting during spring and autumn,
– Middle setting during mild winter,
– Right setting during cold winter.
When you adjust the temperature, the set value is shown
in the display (2). After five seconds the display returns
to standard mode (the current heating flow tempera-
ture).
Normally you can adjust the knob (1) continuously up to
a flow temperature of 75 °C. However, higher tempera-
tures can be set on your appliance, have your engineer
make adjustments so that you can operate the heating
system at higher flow temperatures.

comfort.
