With DN25/DN32 groups
Closed bypass:
- The groove of the screw (2) is positioned at a right angle to the edge of the bypass channel (3)
Opened bypass:
- The groove of the adjuster screw (2) is positioned parallel to the edge of the bypass channel (3)
See corresponding figure.
It makes sense to open the bypass when the heat generator temperature level provided is always much higher than the required tempera-
ture in the heating circuit (e.g. wood-fired boiler in combination with underfloor heating). The displacement of the mixer increases so that
the servomotor can be regulated more accurately by permanently lowering the temperature level in the heating circuit supply line.
