Climate control is simply to save you messing with the temperature controls, it'll keep (or at least do its best) to keep the cabin at a constant temperature by adjusting the heat at the vents as it sees fit.
During the winter there's no need to have the air-con on as the outside temperature will always be cold enough to work with the heat from the engine to keep the cabin at whatever temperature you want.
In the summer the climate control needs the help of the air-con to keep the temperature low as the outside air would be too hot.
So, in winter, press the snowflake button so the light is off and the air-con won't kick in. If you think it's too hot in the cabin despite setting the temperature on the dial to a low value then you need the air-con on.
Having said that, I still can't remember what fiddling with the buttons in the centre of the left and right dials does. I'll look at the manual now and again, think I've got it...and then promptly forget.
All the best
