Heating and Air Conditioning
The Polo 2010 uses the same heating and air-conditioning concept as the previous model.
Three variants are used:
- The manual heater and ventilation system
- The semi-automatic Climatic air conditioning
- The fully automatic Climatronic air conditioning
Each variant has its own operating unit. The control units for the heating and ventilation system as well as for the Climatic are available with or without chrome trim depending on the vehicle equipment. All temperature and ventilation-related controls as well as the air conditioning system control unit are combined in one operating unit.
Feedback LEDs for recirculation mode on the manual heating and ventilation system and on the Climatic semiautomatic air-conditioning system are new on the Polo 2010.
Manual heating and ventilation system
The temperature flap and the flaps for the air distribution are adjusted with the rotary knobs on the operating unit. The adjustment is transferred to the flap mechanism on the heater unit via a flexible shaft.
The recirculation flap is closed and opened with the recirculation flap button. The recirculation flap is operated with a control motor.
When the recirculation flap is open, this is indicated by the feedback LED.
On vehicles with a diesel engine, the auxiliary air heater element Z35 ensures fast heating of the interior. The auxiliary air heater element button is operated by a microswitch located inside the operating unit. The switch is activated when at least 90% of the heating power is selected on the temperature knob.
The “Climatic” manual air-conditioning system
The air conditioning system control unit J301 is located behind the air-conditioning controls. All signals from the sensors and actuators are sent to the control unit and evaluated to regulate the interior temperature. The temperature flap is adjusted by an electric motor. The central flap, footwell flap and defrost flap are adjusted with the air distribution knob via a flexible shaft.
“Climatronic” fully automatic air conditioning
All functions are controlled fully automatically on the “Climatronic” air-conditioning system.
The Climatronic controls have been revised in some areas:
- The “ECON” button has been replaced with the “AC” button
- Changed button symbols
- Ambient temperature indicator omitted
- “Spanner” symbol for diagnosis mode omitted
