One of our local congregations put in a centralized control system for heating and A/C. There were tiny sensors in the wall in each room. From the central station we could see the temperature, humidity, and air flow rates everywhere in the building. Great, right?
Still we got complaints of "it's too cold", "it's too hot", "it's drafty", "it's stuffy". It mattered not what the real conditions were people blamed the system.
One of the old guys went to the local DIY store and got some cheap home thermostats. These got screwed to the wall in every room. The complaints stopped. If someone did not like the room condition they got up and twisted the knob.
