Notes for vehicles with map-controlled cooling
◆ -> A heater control with an additional electrical component -A- is installed in vehicles with map-controlled
cooling. Switch -F269 for temperature selection rotary knob and potentiometer -G267 for temperature se‐
lection rotary knob are installed in this component (potentiometer = variable resistance).

◆ -> Two-way valve -N147 is actuated via switch -F269 (contacts 1 and 2) if rotary temperature switch -A- is
at "cold" stop. This then switches vacuum through to refrigerant shut-off valve and the refrigerant shut-off
valve shuts off the flow of refrigerant through the heat exchanger in heater.
