Door Control - Manual System

While the ignition is on, the position of the recirculation doors is manually controlled by selection of the recirculation switch on the control panel and the steering wheel recirculation switch (where fitted). If the recirculation doors are in the recirculation position when the ignition is switched off, the ATC (automatic temperature control) module automatically sets them to the fresh air position, to ensure that fresh air is available if a fault occurs with the recirculation door drive circuit at the next ignition on.

The positions of the distribution doors are manually controlled by selection of the distribution rotary switch on the control panel. The doors are also automatically positioned by the ATC (automatic temperature control) module to open the:
^ Windshield and footwell outlets, when parked heating is initiated by the FFBH.
^ Face and footwell outlets, when parked ventilation is initiated.
^ Windshield outlets, when the ignition is switched off and the ambient temperature is less than 0 degree C, or windshield and footwell outlets when the ignition is switched off and the ambient temperature is 0 degree C and above.
