Image 4: Setting the temperature limit (before/after)

Pull the control knob off the central plate so that the adjustment rings are vis-
ible Bild.

Pulling off is done by hand or with a suitable tool, e.g. vacuum lifting tool or
key cap puller.

Turn the large blue adjustment ring clockwise to the desired minimum temper-
ature. Each notch corresponds to a change of about 2 °C.

Turn the small red adjustment ring anticlockwise to the desired maximum tem-
perature.

The respective adjustment ring can only be turned in one direction. To return
to the original setting, continue turning to the respective position.

Replace the control knob, observing the coding (Fig. 4, bottom) of the control
knob and rotary axle.
