I think the Suzuki Baleno's owner's manual gives a better understanding about what climate control A/C is all about.

Reviving this very old thread.

I have one technical question to the AC gurus. My friend is owning a Ford Figo TDCI (June'10 manufactured). Figo does not come with the climate control. But, he wanted to see if that can be installed after market. Is this feasible and if so, is it recommended?

Hi

I apologise if there is already a thread for this but I spent a lot of time searching and did not find anything related.

I have a question. Is there a way to choose what the "auto" switch will do in an automatic climate control (ACC)?

My frame of reference is the Honda City 2014 SV CVT and the ACC chooses the front vents as default when you select "auto". I was wondering if there is anyway I can choose both the vents facing the driver and the vents directed at the feet when I choose "auto"? In short, can I customise what settings fall under "auto"?

Apologies again if I have committed a posting faux pas.

Cheers

If i am not mistake the whole point of auto is that, the ecu will decide how to keep the cabin cool, and it will do the diverting as required to center, floor etc. Basically system will have multiple sensors and according to the reading will divert the air. Moment one presets it will no longer be auto.

As far doing it in a car like city, i think would be quite a task, coz you will have to hack into the codes of the climate control and alter it. Crude way can be mechanically locking it in such a position, but then it will no longer be auto climate.

Thanks Jaggu.

I had an inkling it wouldn't allow me off the bat. Just wanted to check if there was an option to maybe alter some settings.

what exactly is a Manual climate control? and how is it different from Automatic Climate control?
Or is the first just a fancy name for an AC? asking based on what i saw on the nexon brochure

It isn't that sophisticated, in 90% of the cars on sale.

There is just one temperature sensor, generally positioned somewhere around the point where the steering wheel column touches/goes into the lower dashboard and the flow of air is regulated going by that sensor's input.

This is also why most ACCs arent really as comfortable as they claim to be and one can see users operating their CC with the kind of air flow and the cooling they prefer over leaving it in auto.

The difference is simple. In a vehicle with MCC, the user inputs the temperature desired by turning the temperature knob from coolest to hottest depending on what he/she is comfortable with. There is nothing to measure that specific degree of temperature, but a general idea of how cool he/she likes the air.

In a vehicle with ACC, the user chooses a temperature, which is generally displayed at different places and the CC system maintains that specific temperature in the vehicle depending on the sensor input that is relayed to it (Jaggu has mentioned the sensor above).

Reviving an old thread.

I have a Grand Vitara 2.0 and it has an Automatic Climate control, although the knobs are round rotatable ones, but temperatures are marked. It has Automatic system which decided Circulation / Fresh mode, direction of Airflow etc.

Recently the AC clutch failed and the compressor was not turning on. The compressor was removed, the AC Clutch repaired and everything put back. Cooling is back to normal.

Now I noticed that the AC Compressor stops rotating when AC Button (Cooling) is turned off. But when it is on auto mode the AC compressor will not turn off.
You turn the temperature to 20 degrees - extremely chilled air will flow out, AC Compressor is rotating.
You turn the temperature to 26 degree - warm air will flow but the AC compressor will still be rotating, and does not cut off.

This is unlike my previous Scorpio with manual AC where the AC Compressor used to cut off when the temperature got to desired cold temperature and come back on after a a while.

So it seems the cool air and hot air is mixed to decide the temperature of the air thrown into the cabin in an Automatic Climate Control and the Compressor is not cut off.

RKBharat correctly mentioned that Manual ACs will be more fuel efficient. Their AC Compressors will cut off when cabin is cold enough. In Automatic Climate Control Systems the compressor will be always running.
