Yeah, I'm probably over sensitive when it comes to system with two control inputs.
It all goes back to when I worked for a large Dutch electrical manufacturer (you can probably guess who) in the '80s. There was a large server room there, with separate climate control systems at each end of the room. Both were set to the same temperature, but the thermostat on one was a few degrees out, so these two HUGE machines just spent their time fighting each other. One trying to cool the room by one degree but never getting there, and one trying to heat it by one degree...
Since then I've always been nervous of any system that has two uncoupled controls driving it.
