programmable lux thermostat for heat pump

Please forgive me for such a simple question:

We moved into a house with a heat pump. We were told that the auto versus the on switch was reverse of what we knew from our our old traditional air conditioner. In other words, on a heat pump we should avoid the auto function and use the on function. However, that doesn't seem to be true in reality at some times, and then at other times it does. Can you please spell out for me the difference between the auto function and the on function when using the heat pump during the summer in Texas as a cooling unit? I hope I have phrased this question right.
Thank you,

Are you talking about the fan switch?
