1. Remove the protective cap or the thermostatic<br />
sensor<br />
2. Lift the setting ring<br />
3. Turn the setting ring anti-clockwise until the preferred<br />
scale value aligns with the reference point<br />
4. Let go of the setting ring<br />

Flow (l/h)<br />
The lines of the diagram correspond to the number of turns of the<br />
bypass spindle (screw). Close the screw completely (right stop) and<br />
then unscrew it the number of turns required to obtain the desired<br />
radiator share. The factory-setting of the CE screw connection corresponds<br />
to a radiator share of approx. 35%.<br />
Presetting can be selected between 1 and 7 in increments<br />
of 0.5. At setting “N” the <strong>valve</strong> is fully open.<br />
Setting in the shaded areas of the drawing above<br />
should be avoided. When the thermostatic sensor has<br />
been installed, the presetting is locked – and protected<br />
against unintended adjustment. In a one-pipe<br />
system, the setting “N” must be used.<br />
