Open the overflow valve fully, close heating circuits
Switch the „Set overflow valve“ menu item from No“
to „Yes“; the circulation pump is then activated with
100% – the pump starts up.
If the control signal UWP 100% has been reached,
close the changeover valve so that the maximal flow
can be ensured (see technical data).
After leaving the „Set overflow valve“ menu or after 1
hour at the latest the circulation pump switches back
to default control
