ducted a/c problem/question

I have a 15.5kw LG single phase ducted system that constantly turns itself off.....it is a fixed speed(non inverter)....which I believe it is supposed to do this when it reaches the desired temperature. But mine on some days turns itself off all the time and I have to turn it back on.
Question 1......the unit is supposed to turn itself back on isn't it? mine doesn't. I have to turn it on myself.
Question 2......when the temp inside reaches the desired temp and it turns itself off.......I know the motor turns off.....should the control panel on the wall turn off as well? As mine does??
I rang LG twice and one guy said yes and the other said no???
Anyone have any ideas?
