Luxury Automatic Climate Control The new THERMOTRONIC luxury automatic climate control, which is available e.g. for the C-class (W203) sports coupé as an optional extra, is controlled by computer, based on various sensor signals indicating the interior and ambient air temperature, air humidity, sunray transmission and pollutant levels in the outside air.
Air in the interior is furthermore kept clean by a large particle filter and two activated charcoal filters, which absorb odors and pollutants in the air.
The driver and front passenger are able to set air distribution and temperature separately, while passengers in the rear benefit from two additional ventilation nozzles in the rear section of the engine tunnel trim.
The individual climate control settings are stored and transmitted to the electronic ignition key, ensuring that THERMOTRONIC will start with the same program settings the next time the vehicle is driven.
