Automatic Temperature Control

kannibul

Maybe this is covered in the manual, but I use this a lot...

I set the fan to auto, the temp 3 clicks to the left of "75", and the zone to auto (or bi-level if my feets aren't cold enough), and set it to recycle interior air (because most of Tulsa stinks...)

Anyhow, one thing I've wondered - is it modulating the AC on/off, or maybe at a reduced rate, or, is it cycling engine coolant through the heater core to raise the temp?
