The switching point can be set within the
range given in the datasheet using a
screwdriver on the setting spindle.
Additionally, you should remove the
housing cover (4 hexagon screws M4).
The affixing screw on the front end
(above the scale) must be removed and
should be reattached after setting the
switching point.
Turning the setting spindle clockwise
results in a lower switching point. Turning
it counterclockwise results in a higher
switching point.
The scale can be used as a guide; for
more exact settings, you should use a
reference thermometer.
