Air management system always reverts to AUTO :(
« December 05, 2019, 09:55:06 »
Excuse me, I have a little "problem" with A/C and air management :)

Does anyone know why (I'm in winter now) when I set air towards wind shield, no A/C, minimum fan speed and 18°C (manual) after some time it automatically switches to AUTO and starts pumping at half fan power cold A/C air (although A/C light is still off) ???

Most irritating, I can't keep it set manually on those settings (and other similar manual setting).  Is there a way to prevent AUTO A/C and auto fan speed?

Thanks

It sounds like your anti-fogging system is kicking in.

Check your manual as to how to disable this.

Hmmmm, doesn't say anything about the system going into de-fogging mode without human intervention.
It says that the system is automatic by default but if you press any button to correct for any settings it disables auto and enters manual mode.  To revert you need to press the "auto" button.

So does i30 have a hyumidity sensor then?  The problem happens after a while, not immediately ...   I'm baffled

Manual is huge, it took me a while to find the right page in the "special features" sub-section.

Ok, found it!   You were right 修羅場,  it does have a hyumidity sensor and it works together with the "ADS" which ensures the windows don't get fogged at any time.
ADS was indeed active!  The manual reports  how to toggle it ON/OFF, no worries.

Thanks, you drove me down the right path.
