normally when you change temps on one, you have to usually change them all, basically 4 times a year, a/c gets turned on, a/c gets turned off, heat gets turned on, heat gets turned off. also sometimes you change them all and then go back and check the temps and your like.... eh ill bump it up one degree and its the same process changing them all. waiting for things to cycle just gets annoying lol.
I'm impressed with the new unit though, It actually saves you money even if your only using 3 of the outputs and offers more features. I'll most likely have one with my new stack.
