Air Conditioning Comfortron System; Control Panel; Temperature Dial; Control Lever - Chevrolet Impala 1969 Owner's Manual

Air Conditioning Comfortron System
Comfortron Air Conditioning adds
the convenience of completely auto-
matic control to the combined heating
and cooling functions of the Four-
Season system, automatically main-
taining the selected inside temperature
regardless of the season or outside
weather conditions.
During warm weather, cooled, de-
humidified air enters the car through
the three dash outlets. During cold
weather, heated airflow will enter the
car through the floor distributor duct.
Control Panel
The control panel makes use of a
temperature dial and a single control
lever.
Temperature Dial
This dial may be set once to the
desired temperature, much as your
home thermostat, and normally need
not be adjusted thereafter. The sys-
tem will run at increased capacity
until the pre-set temperature is
reached. Further movement of the
temperature dial will not decrease the
time needed to bring the car to this
temperature. However, since individ-
ual comfort requirements vary con-
siderably, you may wish to vary the
dial setting slightly to compensate for
warmer or cooler weather.
Control Lever
In the OFF position, the system is
turned off and no air enters the car.

However, it is not necessary to turn
the system to OFF when leaving the
car. It will then operate automatically
whenever the car is started.
During warm weather the system
will go into operation almost immedi-
ately, but cold weather operation will
be delayed until the engine warms up
enough to supply heat to the system. In
cold weather, immediate blower oper-
ation can be obtained in the DE-ICE
position.
Normal Operation-Set the lever to Lo
for completely automatic in-car tem-
perature control. This setting allows
the system to utilize five blower
speeds, resulting in low to moderate
airflow.
When greater airflow is desired or
in severe weather extremes, set the
lever to Hi. The system, still under
automatic control, will now make use
of five higher blower speeds resulting
in moderate to high airflow for rapid
cool down or heating. Blower speeds
will decrease as the temperature ap-
proaches the dial setting.
