That's interesting Aaronng, would the reverse also apply - let's say during summer - if the cabin temp is above set temp - even though the A/C is off would it also refrigerate the air and circulate it? - I think I have also noticed this during summer time

If the cabin air temp is above the set air, what happens if the air flow is set to cooling mode (main vents), but the compressor is not on (A/C button off means compressor off) , so you won't get cooling. But you do get more air blowing at your face since the main vents are used and the fan speed is still controlled.

If your cabin temp is below the set temp, then the vents used are the leg vents (and maybe windscreen vents) and the air is routed past the coolant system.

So even if you turn off the "climate control" by pressing the A/C button, the part of the climate control that changes the output vents and fan speed still works.

Edit: Just realised that your guys are describing air coming in eventhough you hit the "OFF" button for the climate control. Well, if you have it set to take in fresh air from the outside before you hit "OFF" (and have it in the heating cycle), then the internal air path is left at that setting even after being turned off. So air is still being forced in into the cabin, past the engine coolant when you drive, giving you heating.

Or when ClimateControl is OFF, maybe they just have the drivers temperature dial set high, such as ~27. It needs to be set to "LO" to avoid the air being heated by the engine.

If we really had to do that just get it to stop heated, I'd say that is a pretty bad design flaw. :eek:

Depends on how you look at it.

I mean other cars have a manual slider to adjust the Cold<->Hot temperature, but the Euro has a Digital dial instead, which works the same way as a slider (when Climate Control is OFF).

Hmm, maybe there was an update between 2001 and 2003. I distinctively remember that feature was listed on the brochure that I saw around late 2002. I almost bought it just because of that feature lol. Try the owners manual, it might say how to do it.

Even if the climate control is off, the thermostat will still be set to the temperature that it was before you turned it off. So if you had the cc set at 27 and the ventilation set to outside air then the air coming in will be warmish. If you had the cc set to 18 before you turned it off then you will get cool air coming in.

Edit: You can still adjust the temperature of the air coming in, even with the cc off.

That is certainly interesting - also I think on the MY06 Euro the seats have been changed a bit - it seems that the seats are a lot more supportive and deeper than my previous 03 model and more comfortable too

What does everyone think?

The 06 seats could do with an adjustable front section.

Unfortunately when raising the seat, it only lifts the rear of the base, resulting in a forward sloped seating position which is quite uncomfortable :(

In the past - people actually recommend you to turn off the A/C button if you are going to use your heater..

Heater like AARONNG said is just fan air blowing in free heat from the radiator/coolant system . If you're racing on the track and the car's overheating, you turn on the heater to lower the engine/coolant temperature (and cook yourself internally!).

A/C is for cool air. Actually I never found out if say my A/C button is ON, but I've turned on the Heater - whether the Air Compressor is automatically turned off or not... does anyone know?

If you press the Auto button it would turn on Air-Con, so you would have to press Auto, then AC off to get he "free" air.

I was told it was just engine heat? but it seems silly that when ever you turn ac off, you're gonna get hot air. * shrugs *

the only way you will get cold air if the ac is off is if you have it of fresh air and the outside temp is cooler than the inside temp or if you open the windows and it's cooler outside

the only way to cet cool air is if it's on Lo however you may have to "Manually" adjust the fan settings so you don't get the fan blowing at you at full speed (if you don't know how to manually adjust the settings please refer to your Honda user guide)

if you have it on Lo and the fresh air is closed than the temp of the car is going to rise through generated heat within the car and also road, sun, and also heat transfer through the firewall from the engine.
