Y’all probably know this and I imagine it may’ve come up in this thread already, but these Midea units don’t just use the follow me temp when you enable that functionality. My understanding is that it gets incorporated in the math the AHU is doing to decide how much heat/cool to call for. My understanding is that the actual temperature the unit is trying to attain is a mixture of the follow me temp, the temp of the air going into the air handler, the temp @ the coils, etc. Basically a side effect of the fact that the firmware was written for a mini split, where the temp at the output is pretty close to the room temp.
Also another thing you probably know but just to mention it, the unit can show you farenheit, but it really “thinks” in celsius. In order to get tighter drift for the set point, I played around a bunch with the offset temperature measured @ the thermostat, while also adjusting the set point. So now, my room will actually be 68, but I have the thermostat set for 66. For me in my situation, that seems to give me the smallest drift, even if it’s super cold out.
