![]() | Re: Climate Control Help Automatic climate systems are limited to always being in auto for the temp, unless it goes to 'Hi' or 'low' then it will just chuck out hot or cold are with no moderation. The vents on some climate systems do move around so it might blow on your feet for a bit then your face then the screen but generally this goes unnoticed and unless you're always thinking about it and feeling the air flow at the different vents you're not going to know. The fan speed on auto will go up and down as it sees fit, this is also based on things like sun load, so setting a cold temp in a hot car on and very sunny day, will result in the fans going on full blast for a bit and then gently slowing back down to a normal rate. Overall though with these things you can pretty much control all aspects of the system manually without too much interference from the computer. If you set the fan speed temp and direction manually, all the system will do is move the hot/cold air blend flap to manage the temp In the cabin, it won't change anything else.

For example, if you press the recirculation button, then the "Auto" light goes out, but the temperature control, the fan speed control and the vent control remain all automatic. That's almost the complete system. I wouldn't call that the opposite of "Auto". "Semi-Auto" seems more accurate to me.

![]() | Re: Climate Control Help No there is a mixer flap which directs the air flow over the aircon evaporator or the heater matrix, the system will control this mixer flap to send the air to either warm or cool depending on what is needed. It does not vary the fan speed to controls the temperature in manual mode. In its fully auto setting, if it's a hot and sunny day and the car interior temp is cold, you set the climate control to a Lower temp, then the automatic climate control will blast out the cold air at a higher speed to bring the temperature down quickly and then slow the fan speed back to normal to maintain the temp, it won't then increase the fan speed again as it will maintain the interior temp using the above method of moving the hot/cold mixer flap.

I just works, so I leave in in Auto. That's what Auto is there for and I'm very pleased with it. Thanks, Mick.
