Remarks on requests from Air Quality Sensor G238 in zone "3" of display group " 014"







Remarks on requests for fresh-air or recirculated-air mode in zone "4" of display group "014"










NOTE:
- If recirculated-air mode has not been requested, "0" may also be displayed instead of "00".
- To prevent possible misting-up of the windows, the "automatic air recirculation" function is limited to approx. 15 seconds when the compressor does not switch on.
- In the event of a malfunction at the Air Quality Sensor G238 , "automatic recirculated air mode" cannot be implemented.
- To clear misted windows as quickly as possible, air recirculation cannot be implemented in "defrost mode".
- The purpose of the Air Quality Sensor G238 is to stop any short-term high pollutant concentrations (peak impacts) in the ambient air entering the passenger compartment. This is achieved by the operating and display module, Climatronic Control Module J255 switching the system from fresh-air to recirculated-air mode after receiving a request from the Air Quality Sensor G238.
- If the pollutant level in the ambient air remains relatively high for a lengthy period, the Air Quality Sensor G238 starts to adapt to the change in ambient conditions by way of an adaptation program, with the result that a recirculated-air request is generally applied for less than 12 minutes given uniform ambient air pollution. In the event of several consecutive peak impact levels, the air conditioner may also operate in recirculated-air mode for a longer period.
