Awesome work! One thing that Cessna does is has a switch we used to use when we were working on weekends that had a timer on it. You had to set the timer to get warmer heat in places.
Also in my classrooms at Cessna, they had thermostats that only allowed the occupants to adjust +/- 5 degrees. That kept people who didn’t understand thermostats from making large temp swings on the thermostat. (Surprising how many engineers did not understand thermostats…)
