1. This mini-split ramps up and down based on room temperature and the set temperature. In cooling mode, it shuts off completely when the room temperature is 2 degrees lower than the set temperature. It ramps up from there and is on full high when the room temperature exceeds the set temperature by two degrees - In normal operation, I have never seen the room temperature exceed the set temperature.
I have gone through the manual a few times and there is no way to cycle the mini-split that I can find. I can control the fan speed instead of auto, but in my case, it runs on low all the time whether I set it to low or auto.
2. My Trane has a variable speed blower, but I have no idea if it has an IAQ mode or not. My installer was not the most knowledgeable.
