Heating and air conditioning
The Eos can optionally be equipped with the Climatic system with semi-automatic control or with 2C-Climatronic.
As the passenger compartment can either be
relatively sealed from environmental influences
(coupé) or exposed to them (cabriolet roof open) the
air-conditioning system needs to be flexible.
The air-conditioning regulation has therefore been
reconfigured for the Eos to increase driving comfort.
During development, the focus was placed on making
manual adjustment after opening the roof
unnecessary.
This was achieved by among other things:
- adapting the fan voltage,
- taking the greater sunlight intensity into
consideration,
- adapting the air distribution in heating mode,
- adapting the compressor regulation and
- the behaviour of the Climatronic.

Compressor operation
When the Eos is driven as a cabriolet, the air-
conditioning compressor only needs to be run if the
required outlet temperature is below the intake air
temperature. The intake air temperature is calculated
from the measured outside temperature and a
presumed increase of 3 °C for the heat from the
engine compartment.
When the roof is closed, the compressor also runs
when the outlet temperature is above the intake air
temperature to dry the air and thus reduces misting of
the windows.
