Temperature Control

Temperature Control

The rotary knob locks in both end positions. The temperature is set by means of a mixing flap that is operated by a stepper motor (bus). The temperature control potentiometer can be turned through an angle of 240°.

The water valve is closed when the control knob is set in the minimum position. From the 10 o'clock position (potentiometer value) on, the water valve is opened and the auxiliary water pump switched on.
