Dual Zone Climatronic
The new Jetta is equipped with a
dual zone air conditioning system. The
temperature on the driver's and front
passenger's sides can be controlled
separately to between 60
° F (16 ° C) and 85 ° F
(29.5 ° C). Pressing the “Auto” button for
longer than two seconds allows the
temperatures on both sides to be
synchronized to the driver's side.
Two air-conditioning zones are achieved by
using two temperature doors within the air
conditioner. All air conditioner doors on the
Dual Zone Climatronic are actuated by six
control motors with integrated
potentiometers. The Dual Zone Climatronic
can be operated either automatically or
manually.
To prevent fogging of the windshield, the
Dual Zone Climatronic automatically
increases air flow to the windshield if the
compressor is off and the windshield
wipers are on. The defrost door is also
opened wider.
The Dual Zone Climatronic also reduces the
fresh air blower speed depending on
vehicle speed. This minimizes the airflow
noise of the air conditioner. The fresh air
blower is automatically adjusted as a
function of road speed. This adjustment in
blower speed is not noticeable by the
vehicle occupants.
