2003 ASTON MARTIN DB AR1 Q heating

D - Heating, Ventilation & Air Conditioning
1-D-6Defrost (A/C Off)
In defrost mode, the system is automatically switched
to high fan speed and maximum heat with no air
conditioning. The hot air is directed to the screen and
door vents only. The door vents may be closed to
direct maximum air flow to the screen.
Right Panel (A/C Mode Switch)
The right panel contains the mode switch and temperature differential
controls.
The mode switch settings are:
Economy (A/C off)
Manual Control
Auto Control
Demist
Recirculation
ECON (Economy)
In the ECON position, the air conditioning compressor is switched off.
Incoming air can be heated if required and the fan speed can be adjusted
to increase or decrease the airflow in the vehicle. This mode puts minimum
load on the engine and gives the best fuel economy with no air conditioning
(no cooling or dehumidifying of incoming air).

D - Heating, Ventilation & Air Conditioning
1-D-7 MAN (Manual)
In Manual mode, the air delivered from the vents
remains at the temperature set on the temperature
control regardless of the temperature inside the
passenger compartment. In this mode, incoming
air is also dehumidified and blended.
AUTO Control
This is the automatic mode of operation in which
the heating and cooling functions of the system
operate automatically, as required, to maintain
the selected in-car temperature. In this mode,
incoming air is also dehumidified and blended.
Note: If the incoming air requires little heating or cooling when in AC mode, the
centre vent will close reducing the air flow in the upper part of the passenger
compartment. If more airflow is required, the Demist function can be used to
provide the same temperature level but with increased air flow to the windscreen
vents.

D - Heating, Ventilation & Air Conditioning
1-D-8DEM (Demist)
When this mode is selected heated air is directed to
the windscreen vents for demisting as well as to the
face level, footwell and door vents. Air speed and
temperature depend upon the fan speed, in-car
temperature selected and engine temperature.
Recirculation
In Recirculation mode, all external air inlets are
closed and conditions within the vehicle are
maintained by drawing air from within the cabin and
heating or cooling it as required before returning it
to the passenger compartment.
Recirculation mode avoids drawing noxious fumes
into the vehicle from outside. This mode is not
recommended for continuous use since no fresh air
is drawn into the vehicle and drowsiness may occur.
The car interior may be rapidly cooled in recirculation
mode by selecting Recirculation, Minimum
Temperature and Fan Speed 3.

D - Heating, Ventilation & Air Conditioning
1-D-9
Temperature Differential Control
This control sets the difference in temperature
between the air from the face vents and that from
the footwell vents.
To provide cooler air to the face, the differential
control should be set fully anticlockwise. If the
control is set fully clockwise, the air from the face
vents will be at the same temperature as that from
the footwell vents.
The differential control is only effective when the
temperature control is set to its mid position.
