4. Function description
4.1. Operation KS20.01
After stress connection the unit is in operability.
After activation of the ignition (X1/2 ) and release of the three-stage rotary switch (X1/4) the heat-
ing control is activated. According to the position of the rotary knob the magnetic valve is actuated
in a time code of 45 seconds.
With the rotary switch 1 the fan can be shifted in three stages.
Is the rotary switch at stage “OFF” the heater is automatically deactivated.
4.2. Operation KS20.02
After stress connection the unit is in operability.
After activation of the ignition ( X1/2) and release of the three-stage rotary switch (at minimum
stage 1) (X1/4) the heating control is activated and the compressor can be activated manually by
the button S1.
According to the position of the rotary knob the magnetic valve is actuated in a time code of 45
seconds.
With the rotary switch 1 the fan can be shifted in three stages.
Is the rotary switch at stage “OFF“ the heater is automatically activated and the air-
conditioning compressor is deactivated.

5. Blink code of the fault- LED (Option)
An the rear side, on the circuit board, next to the connection plug there is a green fault-LED. This
informs about the status and the operating state of the KS 20.10. After impressing a voltage on it
the LED lights for 60 seconds. In regular operation the LED is OFF.
