As I underrstand it, if it is the same as a domestic split system, auto means that it heats or cools as required. So if you set it to 19 on auto, if it eventually cools it down to 18, it will then start heating until it goes back up to 20, at which point it will start cooling etc etc. If you have it on cooling and 19, it will just cool it until it is 18 then switch off, and turn back on when it goes above 20. Auto in the winter does the same thing, if it gets above the set temp, it starts cooling. I would never use auto for anything.
the thing with auto is that it has a tendency to keep the fanspeed and low and cool more.
if you put it in manual you can ramp the fan up so it blows on your body which makes it feel a lot cooler than it actually is.
hence my question which is more energy efficient. when the midday sun is up to feel comfortable on auto you really have to set it to i.e. 19 degrees.
